Algebra II: You are making a rectangular box out of a 10.75inch by 17.25 inch piece of cardboard. The box will be formed by making square cuts out of the corners of the cardboard. You want to make a box of greatest volume possible. Find the largest volume for the box.

Elementary Functions: Look at section 4.4, p. 376 - 377 #1, 9, 19, 23, 25
Come up with some ideas of what happens to the basic functions sin(x) cos(x) and tan(x) when you apply different transformations to them. Please, feel free to play around with different values in different places and record your observations. Also, it wouldn't hurt to read over the section and try to make sense of some of the examples. I intentionally pick new examples for class so that you have multiple problems to look at when you practice at home.


Please study your table!!!! (SinCosTan, 0,30.45.60.90)

Wednesday, December 19th, 2007

Algebra II: P.357 10-17 all

Elementary Functions: Finish 4.3 and please study your table!!!! (SinCosTan, 0,30.45.60.90) I will not be around on Thursday or Friday after 2pm. All ch3 tests must be made up by Dec21st.

Tuesday, December 18th, 2007

Algebra II: Nice job on the quizzes, though it took you a long time! I just suspect that you haven't had enough practice to do them quickly, but that you are at least familiar with the topics. Either way, nice job and keep up the good work! No homework.

Elementary Functions: As suggested, there will probably be a quiz tomorrow. Block A and C: Sec. 4.3 Trigonometry Extended: The Circular Functions

Monday, December 10th, 2007

Algebra II: Finished the test today -- we will be starting chapter 5 tomorrow, and have 2 quizzes and possibly 1 test before break. Be sure you're on your A-game!

Elementary Functions: Project was due today -- if you haven't turned it in, make absolute sure that you do ASAP.

Test was today, and I hope you all made it out alive. I hope to have scores by tomorrow possibly -- Wednesday at the latest. If you are already planning a retake, retakes need to be done BEFORE break.

I would like you to start chapter 4 by yourselves -- we will be doing our best to get this chapter done by break. This means a fairly aggressive pace, so I hope you are up to it! You would be best served if you read the entire first section alone, but i am only requiring P. 338-339, and that you work on 1-8 all on p343. The scan has pages 2 and 3 transposed, but you can click through.

Once I introduce Sine Cosine and Tangent, you will be required to memorize Sin,cos,tan of 0,30,45,60 and 90 degree angles. There will be a quiz this Friday of just that, so you can do yourself a favor and look up a table, or wait for it to be introduced in class and take careful notes (also, I suggest flash cards).

Finally, here is the pool that I will be assigning homework from in the next 2 weeks:
Sec. 4.1 Angles and Their Measures
p. 343 – 345 #1-13 all, 19-33 odd, 35, 37, 41, 43

Law of Cooling problem

Monday, December 3rd, 2007

Algebra II: P. 312 6-14 evens, remember y=a(x-h)^2 +k The test will most likely be Wednesday or Friday!
Fridays was p. 323 1-9 odd

Elementary Functions: P. 313 1-16 all, graphically only (you don't need to draw the graphs, but put the left hand side into y1, the right in y2 and graph -- then find where they "are equal". OR, you could subtract one side, to get the whole thing =0 , then graph the side and find all zeros.

Test in both classes is now scheduled for Friday, but I will probably push it back to Monday... I will keep you posted. For now, be sure you're looking to the chapter review and can say something about the concepts (p.327) and can follow what they have listed under properties, theorems, and formulas, as well as procedures (p.327-329)

Elementary Functions: Look over your homework -- do you see any ideas repeated between 2.7 and 3.1 so far?

Also, look into a few more resistor problems (in parallel). I am probably going to give you one of them on a quick quiz when we get back from break. If I don't see any of you tomorrow, have a wonderful and relaxing time with your families. If I do see you tomorrow, I hope you will be supporting the Turkey Fund!!!!
No new homework (a or c)

We will start Chapter 4 tomorrow!

Elementary Functions:
Blocks A and C: Test tomorrow is on chapter two, from 2.1 through 2.5 including the two statements from class today (below)


The Fundamental Theorem of Algebra
A polynomial function of degree n>0 has n complex zeros. Some of these zeros may be repeated.

A polynomial function of degree n>0 has at most n real zeros.
** we also have shown that a polynomial of ODD degree has at least 1 real zero, but even degree does not have that quality

Suggested practice: P.253, #1, 5, 9, 17, 21, 22, 25, 29, 31, 37, 39, 40, 41, 42, 44, 53, 86

Study: Writing linear equations and quadratic equations given two points
Writing Power functions from a verbal model
Constant of variation
Dividing polynomial functions ** also
Remainder theorem
Factor theorem
Rational Zeros theorem
Adding, subtracting, multiplying complex numbers
Finding real zeros through Rational Zeros theorem and using the grapher or solving
Polynomial properties (a 3rd degree looks like..., a 12th degree looks like...)

In effort to support the little guy, if by the end of the quarter I have more visits to my website by Firefox than by Internet Explorer (the race is very close currently) I will curve the overall grades by 1% point.

Elementary Functions: Block A: P.133 1-20 all

Block C: Study study study. Start by looking back at homework. By now you should be highlighting or marking things you did not understand in previous assignments and you should go back to try the problems again. Additionally, look through quizzes and see what you did not do well on -- these are things to keep practicing with. Finally, look to the chapter review exercises ( p.150-152 in this chapter) and try the problems - you should be pretty familiar with most of the topics and all of the terms in the concepts/properties/procedures on the previous pages should be something you can explain in a sentence or two.

If you can do p.150, 1-58, you should have no trouble with the test tomorrow. Do not worry about horizontal stretch/shrink, but do know how to use a vertical stretch/shrink!

Algebra II: P. 109

Elementary Functions:Block A - Worksheet, all 4 problems.

Block C. P.106 41, 44, 45 -- try 45, do your best, I'll try to post some more info later if I can. or here


I cannot say enough, if you are struggling, come in for help! I can make myself available before school, during majors and occasionally after school by appointment. If you are a real early bird, let me know and I will bring you up before 7:15 if you plan on working.


Ten basic functions:

y=x
y=x^2
y=x^3
y=1/x
y=sqrt(x)
y=ln(x)
y=




For 45B: understand that f(x+y)=f(x)+f(y) means that if you pick any two numbers (let's just pick 6 and 33) setting x=6 and y=33, then plugging 6+33 ( which =39 ) into the original function would give you the same value as plugging 6 into the function, getting your answer, plugging in 33 to the function, taking that answer and adding to your original answer. Let's try it with x^3:

f(x)=x^3
f(39)=39^3 = 59319

check if f(6) + f(33) is the same

f(6)=6^3 = 216
f(33)=33^3 = 35937

f(6)+f(33) = 216 + 35937 = 36153 which is not 59319, so the answer to b is not f(x)=x^3


Similarly, d means to take 6*33, input that to the function, then check if that is the same value as above (namely, f(6) + f(33) )
Hope this helps!

Wednesday, September 26th, 2007

Algebra II: Nice job in the lab folks, no new homework, but last night's work is worth double! Be sure you're done!!!

Elementary Functions: Homework for both blocks is P.105 1-20 all. The first 10 are matching the 10 basic functions (some slightly modified) from the project to their graphical representations. Be sure you can identify functions from either model (algebraic or graphical). The last half of the assignment talks about the properties of the functions.

Link for homework (again, megaupload makes you type in 3 characters to verify you are downloading... please ignore any ads, I wish I could do this free somewhere else.)


Finally, this is mostly for parents, but if you want a grade report to be emailed to you, please send me email (so I have your contact information) or comment to this post and I can add you to my list.

Elementary Functions: No homework, either block

Block A, be sure you're working on your projects, I will not be giving you much class time to finish -- this is up to you!

Block C, you have your test back, if you're still scratching your head, COME IN!!!! I'm at school by 6:30 -- you are allowed up at 7:15, I will be happy to spend time with you on any topic. If you would like to retake a test, my general policy is that you have scored 60% or below (up to 70% with permission) on your first attempt, and you prove to me that you have done work to better understand the topic(s) you weren't successful with. I will award you the 2nd score (higher or lower) after I evaluate your test. You MUST see me if you plan to do this, and you must tell me at least 12 hours in advance of taking the retake (in person, or email runderwood2@pghboe.net).


Good luck.

Block C: Study!

Sunday, September 16th, 2007

Algebra II: Test will be Tuesday, be sure you can do problems from each of the sections in chapter 1. Test topics should include simplifying expressions, solving equations, solving equations for a given variable, solving and graphing inequalities and absolute value equations and inequalities.

Elementary Functions: Test will be strikingly like the homework/classwork, I hope you followed along. First, I would look at the key ideas on page 55 and be sure you can say a good sentence or two about each concept. Next, in Properties, Theorems, and Formulas the list, be sure you know and understand the distance formula, midpoint formula, and quadratic formula. Be sure you are comfortable with interval notation and have some idea of domain and range. Finally, equations of circles are fair game, so you should know how to write the equation of a circle given a point and radius or work backwards given an equation, finding the center and radius.

Friday, September 14th, 2007

Algebra II: P55-56 7 problems
34, 35,64, 66-69

Elementary Functions: P. 53 do 1, 4, 7, 10, 13, 31, 35, and we will talk about 38 in class so be sure you've looked at it and can follow along.

To those that have not taken the assignments seriously, I hope you reconsider their importance. Yes, the assignments only make up 15% of the total class grade, however, quizes and tests are drawn directly from the assignments, so homework is your best chance to practice.

Wednesday, September 12th, 2007

Algebra II: No new homework, just finish what was assigned yesterday.

Elementary Functions: No new homework, just complete the assignment from before for Friday. I am planning on a test for Tuesday and will try to post a list to study by noon tomorrow.

Homework (if you forgot) is p.45-46 1, 4, 7, 14, 19, 45, 55, 59, and 62

Link is availble from Monday's post.

Tuesday, September 11th, 2007

Algebra II: *due friday

It may seem harsh, but that is only 16 problems!

Elementary Functions:

Block A: Make sure you're comfortable with linear and be ready for quadratics tomorrow.
HW: p. 37 37-40


Block C: We're getting a little behind schedule, but it's better to be sure that factoring isn't an issue, and that we can knock this out early.
PDF is big, so try either tonight/tomorrow link, they are two different servers but the same file
Tonight p.45 1-18all

Friday, September 7th, 2007

Algebra II: No homework -- quizzes look pretty good, I'll have them back to you this weekend.

Elementary Functions: Block A - finish P.18, 37 &38a - it's easier to write here than scan:

37. Prove that the figure determined by the points is an isosceles triangle: (1,3),(4,7),(8,4)

38. Prove that the diagonals of the figure determined by the points bisect each other:
(-7,-1),(-2,4),(3,-1),(-2,-6)

Blocks A & C : I realized I haven't posted grading rules for you, sorry!

Classwork 15%
Homework 15%
Projects (take home & in class) 10%
Assessments 60% (Quizes 15%, chapter tests 45%)

If you think your last quiz was poor, there will be plenty of opportunities to redeem yourself.


Also, remember the 3-point circle problem? Check this out: http://www.delphiforfun.org/Programs/Math_Topics/circle_from_3_points.htm


Have a great weekend!

Thursday, September 6th, 2007

Algebra II: Finish through the worksheet, you have plenty of examples worked through, so hopefully we can be successful tonight.



Elementary Functions: Ugh, linear? really people?! I guess that's why we are reviewing first. P. 35 7-17

If you already have your calculator, take a few seconds and follow the directions for 3-7. I'd like to move through the rest of the P chapter as quickly as possible.

P. 30&31
6-10, 15-18

Elementary Functions: Block A was interrupted by the junior meeting, but we'll have a full block tomorrow to discuss coordinates and circles. Block C finished the circles section, but left one question unanswered: Can you define a circle given that it passes through the three points (0,sqrt(3)), (sqrt(3),0), (-sqrt(3),0) ?

Algebra II: Fire drill slowed us down in class, so there is homework: P. 14, #26-28, 34-36, 43-45, 52-54. I will be collecting this first thing on Tuesday, so be sure to have it done!

Elementary Functions: Domain is the set of all x values, or the input for the function. The range is the set of all y values, or the output of the function. Remember which door you came in on the first day and how you decided which door to go in -- all functions work this way. If you are in the domain (the set of acceptable values for x) you have one and only one clear path or value (the output of the function). The function will let you know if you are not in the domain by either not directing you to an output, or by giving you an error or invalid operation (dividing by zero).

Note, I am using <= to mean less than or equal to, and >= for greater than or equal to. < still means less than and > still means greater than.

Homework was to graph the following function: f(x) =

x if 12<=x<=15
(1/2)x^2 if 3x^3 if x<-2
x^4 if 0(x+1)/(x-1) if 1log (x) if x>15
e^x if -2sqrt(x) if 10<=x<12




Thursday, August 30th, 2007

Algebra II: Homework is P. 6 #3-8, this should take you all of 5 minutes! Please take the time to go through this first section and look at the example problems on p.2 through 5. I do not generally go over these exact problems in class so that you can look at them for help with homework. Since I like to give quizzes on Fridays and we haven't had much class time together, I would be sure to look at examples 1 and 3 for tomorrow.


Elementary Functions: Today we talked about input and output of functions (domain and range) and classified coordinates as being natural numbers, integers, real numbers, imaginary numbers and rational numbers. Your assignment is to describe in words the domain and range of the following piecewise function:
3 if x>1
y =
4 if x<-1



Course syllabuses (http://en.wikipedia.org/wiki/Syllabus) are still to be posted -- I am looking for a good file repository to use (if you have a good suggestion, be the first to mention it to me for bonus points!). I have tried looking into google docs, geocites and this blogger account, but I need the ability to upload PDF and DOC files for you to download. Help?

Welcome Back!

I have my schedule for the 2007-2008 school year!!!

I can't wait to see you all in class



Semester I

Reminder for both:

Class schedule for the remainder of the week

Tuesday -- Final "normal" class day - "Show and tell", I show you a problem, you tell me how to do it!

Wednesday -- Practice open ended exam - 1/2 work time, then 1/2 block going over step by step.

Thursday -- Final exam part I, open ended. THIS IS THE REAL DEAL! BE READY!!

Friday -- Practice final exam multiple choice - 1/2 work time, then 1/2 block going over step by step.

Algebra II: "Suggested" p.1014 4-20 evens


Algebra I: Finish the worksheet AND create a survey to poll a population. Then describe how you would choose groups for each of the different sample types.

Friday, JUNE 1st, 2007 (not to scare you or anything...)

Algebra II: P. 1013 17-24 all.


Algebra I: No new homework.

Thursday, May 31st, 2007

Wow, it's already the end of May. Don't forget, there are only 4 classes until the open ended final exam!!!

Algebra II: Thank you to all that turned in their projects early. Homework is P. 1013 1-16all. Be ready to hit the ground running tomorrow!


Algebra I: Practice working with inequalities and graphs of inequalities -- I hear there will be plenty on the final in several forms. Also, be sure you are working on your quadratics, they will make up the bulk of the the exam. Homework is the worksheet from class covering linear equations.

Wednesday, May 30th, 2007

Sorry there wasn't a post yesterday, tied up in meetings and it slipped my mind until I was elbow deep in dirt. Sadly, my garden does not have internet access.

Algebra II: P.1013 5-11 all -- review for the final! Remember that the open ended portion is June the 7th.


Algebra I: p. 419 1-13 -- review for the final! Remember that the open ended portion is June the 7th.

Friday, May 25th, 2007

Algebra II: Work on your project -- it is due on Wednesday. Look below for the writeup.


Algebra I: We went to the lab on Friday, and most people are catching up to where they are supposed to be. Only 3 more lab sessions left! No new homework.



Review Project

Your task is to prepare both yourself, as well as your classmates for the final. I have broken down the material that we covered this year into small packets of 1 to 4 sections for each of you to tackle.

First, you must re-familiarize yourself with the subject matter. Do this by picking up your book and actually reading the section. Yes, read every page, every word – we may have missed something in our fast paced romp through the book. Second, start an outline of the section(s) and be sure to focus on the Key Concepts in each section. You are producing a document that everyone will look over to study for the final, so be thorough. Next, create four UNIQUE examples (not examples from your text or notetaking guide) and work them through to completion. It is very important that you check your work with these examples to be sure you are correct! Finally, create 4 questions and supply answers separate for review/quiz use. Two of your questions will be used on an in class review quiz, and two will be used just for review..


Breakdown of points:

Class work portion:
Thorough outline of section(s) 15 points
Key Concepts clearly shown 5 points
Homework portion:
Examples with solutions 10 points
Questions for review/quiz 10 points

Total value for assignment (scaled by a factor of 2) 40 classroom pts
40 homework pts

Thursday, May 24th, 2007

Algebra II: See you at prom tonight! I assigned sections of the book to outline and make a study guide for your peers. EVERYONE needs to pull through on this one for it to be beneficial! Expect more detail in class tomorrow, but for now (if you have time) look over your section (I will publish a list in class if you forget your section) and familiarize yourself with the main ideas.


Algebra I: Finish the review worksheet, I will collect them at the beginning of class tomorrow for double credit (you had two nights!).

Wednesday (finally), May 23rd, 2007

Algebra II: Chapter test as promised, looks like everyone blew off studying. Hopefully this doesn't mean you have shut down for the end of the year -- we still have a lot of work to go before you're officially done. I reminded everyone to look at chapter 3.5, we didn't discuss this in class, but there is a question about it on the final. We will likely make SHORT mention of it during a review, but do not expect to understand it just from a brief review!


Algebra I:Tests look ok -- i feel that all the homework that the class is NOT doing is showing up on the test... I really really need to remind you all that if you are not doing the homework, it is going to be almost impossible for you to be successful on exams. Homework tonight is the review sheet. Most people have it at least 1/2 done, and if you have to skip some, skip the LAST 5. See you tomorrow!

TUESDAY, May 22nd, 2007

Sorry, I guess I thought it was Wednesday already...


Algebra II: Homework is to work on the worksheet, problems 1,4,7,8,11,14,17. Test is tomorrow, so study up!


Algebra I: Remember the test is tomorrow!!! Homework is p.705 4,5,6 and the 4 problems from class p701 11,14,17,20 This will be a double credit assignment!

Monday, May 21st, 2007

Algebra II: Study, also, be sure you're up to par with the cognitive tutor -- i'm adding grades by the end of next week!


Algebra I: Please be sure you are making progress on the cognitive tutor - if you need more time, I have two extra computers in my room during a.m. tutoring time. Homework is P.701, left column. DON'T SKIP THE WORD PROBLEM!!!

Friday, May 18th, 2007

Algebra II: STUDY


Algebra I:P674 13-20 all

Wednesday, May 9th, 2007

Algebra II: We finished off ellipsis and finished the worksheet for homework -- the last three problems should be the only thing that you have to worry about, and please remember to label the foci!


Algebra I: Don't forget "Pop goes the weasel"! Thank you to Ms. Rudolph for helping us and thank you Chelsey for playing. Homework is p. 674, 3-12 all.

Tuesday, May 15th, 2007

Algebra II: Looks like this is sinking in -- homework is to finish the 9.3 side of the worksheet, and try to graph 1&2 of 9.4.


Algebra I: Homework is p.655, h(w)=[(6w)/3]+17 with a domain of 0,1,2,3,4,5,6

Monday, May 14th, 2007

Algebra II: Nearly everyone finished the worksheet in class, I hope you all can apply the last chapter's skills to this chapter! Look for a quiz on thursday that will focus mostly on finding focus and directrix, and finding radius of circles in standard form.


Algebra I: Homework was page 655, h(w)= [(6w)/2] + 3 with a domain of 0,1,2,3,4,and 26/6. We will be in the lab tomorrow, and the homework will be p.655, h(w)=[(6w)/3]+17 with a domain of 0,1,2,3,4,5,6

Friday, May 11th, 2007

Algebra II: I hope you all enjoyed Walkin'for Wishes, and remember that it was to benefit the Make a Wish foundation. Homework is an extension on last night's work, p. 623 7-10 all. please be sure to LABEL your focus and directrix !!!!!


Algebra I: AAACK! I can't find the page, but it was 1-10 all -- mixed review or quiz?! I'll look at my book when I get home tonight or tomorrow morning and post - Sorry!

Thursday, May 10th, 2007

Algebra II: x^2=4py and y^2=4px is starting to make more sense -- just like the log equations, you really just need to memorize these forms and you'll be ok. Homework is in the book, p.623 1-6 all, full credit will only be given if graphs are attempted to be accurate (no sketches!)


Algebra I: We discovered that zeros, solutions, x-intercepts, where the graph crosses the x-axis and solving the function all mean the same thing. Homework is the worksheet from last night -- thank you to the 3 people that actually did it last night, you don't have any homework tonight.

Wednesday, May 9th, 2007

Algebra II: Talked about the focus and directrix and axis of symmetry. Homework is to write the standard form of the equation of the parabola with vertex at (0,0) and the directrix x=-3/4.


Algebra I: We finished (hopefully) the packet talking about transformations in quadratic functions. The homework is a worksheet asking you about transformations. You get to choose the values of a, c, h and k, so you are making the transformation and then describing what you have done in the function.

Tuesday, May 8th, 2007

Algebra II: No new homework, make sure you finished last night's which was P.138 1-9 all, 1-3, be sure to describe your transformations!

If you are not on unit 25 in the lab by now, be absolutely sure that you have a plan to be working on the tutor during mornings (there are no after school tutoring sessions left!)


Algebra I: Homework is P. 638 1-5, 12-15, 27, 37 Double points!!! Also, if your name has an A in it, then please clean your room (you know who I am talking to).
Finally bring your packets from last week to class tomorrow!!!

Monday, May 7th, 2007

Algebra II: We worked in the lab today, and most people are finishing through Unit 17. If you are not on unit 25 by now, be absolutely sure that you have a plan to be working on the tutor during mornings (there are no after school tutoring sessions left!) Homework is P.138 1-9 all, 1-3, be sure to describe your transformations!


Algebra I:We worked on quadratic equations with a bx term in them. Remember that equations look like y=+- ax^2+bx+c where +/- makes it open up or down, a is a dilation that makes it skinny if you use a value greater than one, and fat if the a value is less than one, c moves the graph up or down, and b moves your parabola in 2 dimensions. Your axis of symmetry is the line that goes through the vertex, and is always in the form of x= ___ while the vertex itself is the maximum or minimum point of your parabola.
Homework is to finish the worksheet from class -- don't forget to get this done, too many people's grades are falling because of homework!

Friday, May 4th, 2007

Algebra II: Tests looked pretty good, the graphing was a bit rough though. Remember that you can always practice domain and range with ANY problem that you graph - just think about what you can and cannot put into the function (domain) and what you can an cannot get out of the function (range)

Homework: P. 129 (yes, p 129!) 43-48 all, and 49-54, describe each transformation from y=x to the indicated function (careful with 52)


Algebra I: Worksheet for homework, do your best with the graphs, and I would suggest that you create a t-table before graphing.

Thursday, May 3rd, 2007

Algebra II: Test is tomorrow -- I suggest that you look at p. 610, the standardized test practice. Answers are: 1.)b 2.)c 3.)a 4.)c 5.)d 6.)d 7.)b 8.)a 9.)1 10.)3.2 11.)31.5 12.)1 13.)23 14.)2ft/s or 4ft/s
Practice graphing y=(2x-1)/(6x+3) y=4/x and y=2/(x-1) +1



Algebra I: Homework is a worksheet on factoring - don't forget that you can use the box to help you factor.

Wednesday, May 2nd, 2007

Sorry this post is a day late -- it had trouble posting yesterday but said that it did post, so I went home for the day. The computer had been acting weird all day and I wrote it off as a network problem. This morning my computer thought it was the year 2032, so I restarted and I think all is working well now.

Algebra II: p. 592 1-5 -- solving rational expressions. Don't forget to set the left side to y1, right side to y2 and 2nd/trace/5 the intersection to check solutions.


Algebra I: Thank you Chelsey for doing such a great job. Students: Chelsey assigned a homework sheet - be careful with the domain and range.

Tuesday, May 1st, 2007

Algebra II: Worked in the computer lab, if you're still graphing in there, you're too far behind! Come during tutoring to catch up so it doesn't start to bring down your grade. Homework is p.595 1-5 all. Don't forget you can use the book online at www.classzone.com


Algebra I: Benchmark went pretty well... Homework is the worksheet that you got at the end of class. Don't forget to list the domain and range for #8-10!

Monday, April 30th, 2007

Sorry, meeting cut my time short this afternoon so this is brief


Algebra II: Worksheet, skip the left column.


Algebra I: Worksheet, only do the right column. Benchmark exam is tomorrow.


Good luck!

Thursday, April 26th, 2007

Algebra II: Still working with rational expressions and simplifying, take a look at 581 if you weren't in class -- it's a good way to check yourself after you have worked so hard on the problems! Expect a quick 2 question, 10 point quiz at the beginning of class -- remember how to factor x^2-144 for the quiz!!! No Homework -- enjoy the musical!


Algebra I: We have multiplied expressions, and now we are learning to factor. Try using the boxes to figure out what you need to multiply in order to find the desired result. Homework is page 578 1-21 odd, but it isn't due until Monday, so take your time with it and check your work carefully. ** Reminder : the benchmark is coming up next Tuesday!!! Be ready!

Wednesday, April 25th, 2007

Algebra II: Sorry for the late post -- HW P. 578 #34-42


Algebra I: HW was a worksheet on multiplying binomials -- be sure to practice, the benchmark exam is scheduled for Tuesday, and I'm told there will be plenty on there!

Tuesday, April 24th, 2007

Algebra II: Went over the assignment and talked more about rational expressions. No new homework -- I hope the PSSA went well!


Algebra I: Lab day today, take it easy tonight and be ready to finish your Terra Nova tests tomorrow. We'll visit the lab again tomorrow, but get back to classwork for Thursday.

Monday, April 23rd, 2007

Algebra II: Today we "closed" discussion on graphing rational equations, and started talking about simplifying rational expressions. Note, because we are working with expressions, there are no equal signs and only one exponent, so we can't graph.... or can we? Throw a y= on the left and you can graph away. So, some of you may have guessed it, we'll be back to graphing soon enough. Tomorrow we're going to the lab, and I won't check this homework until Wednesday so if you are reading this, get some extra sleep and be ready for the PSSA Science test. There will be a SHORT additional assignment tomorrow, but you'll have no trouble lumping the two together and getting them done by Wednesday. "Tonight": p. 578 18-22all , 24-30 all


Algebra I: You must think it's Christmas again because there's no homework, instead, go home and get a good night's rest to be ready for the Terra Nova. Remember these go on your record, and help us decide what classes to place you in next year and beyond so do your best!

Friday, April 20th, 2007

Algebra II: Quiz seems to be decent, I think the class did well. Thank you to those of you that worked on your projects the last two weeks, most looked really good. Anyone that did not finish your project already, remember, every day at 9:20, I subtract 10% if I don't have it in my possession! Homework was the "quiz" p. 571, 1-10 and the graphs just need to be sketches -- just be careful with your asymptotes.


Algebra I: No new homework, just rest up and be ready for the Terra Nova tests on Tuesday. Good luck!

Thursday, April 19th, 2007

Algebra II: Don't forget to finish your projects. I am going to be looking at your choice of equation to model your data very closely, so be sure to back up why you chose that type of equation. Quiz tomorrow will cover domain, range, vertical asymptotes, x and y intercepts and graphing. As long as you can do the example problems from 8.1 to 8.3 you'll be fine.


Algebra I: Quiz tomorrow! Sum, difference and product of polynomials, without any special bells or whistles. I'm collecting the homework from Wednesday for 2x the points, be sure you bring it!!!! No new homework -- study up!

Wednesday, April 18th, 2007

Algebra II: We worked on graphing rational functions with different degree in the numerator and denominator, don't forget to use your notetaking guide to help P. 568 1, 3-6, 13-14 and finish the two checkpoint problems from the notetaking guide.


Algebra I: Remember to think about test taking strategies -- the Terra Nova's are coming!!! Homework is to work on special products of polynomials and the worksheet from yesterday.

Tuesday, April 17th, 2007

Sorry folks, was still worn out from being sick, I forgot to post on Monday. Alg2 - no homework, Alg 1 - worksheet which I did not collect during class because so many students were out.

Algebra II: New homework, old topic -- graphing. Homework was page 561, #1-13odd, mostly graphing, and since I gave you graph paper, I want accurate graphs. Thank you! Look for a quiz on Friday asking about Domain, Range, Asymptotes and a little graphing.


Algebra I: Not to worksheet you to death, but I gave you one more problem to hopefully connect the current subject to real life experiences. Note, please be sure to practice FOIL, there will be a quiz on Friday.

Thursday, April 12th, 2007

Algebra II: We had a great discussion on our past graphs, domain and range -- I think everyone is really getting it. We also started inverse variation today, and got through most of 8.1. Homework is P. 555 3-13 all and 37-40 -- focus on 37 through 40 and be sure to read the questions at least twice BEFORE you start working on the problem!


Algebra I: Cognitive tutor lab day - by the end of class today, you are expected to be done with Unit 32. If you are not through 32, you MUST see me about catching up before/after school. Homework was a worksheet -- sorry, still can't attach a PDF, just a picture... Any suggestions??

Algebra II: We finished the unit on the computer and moved on to a new section. Students received a copy of their project and MUST sign up for a particular country -- don't forget! Homework: Left column of worksheet


Algebra I: We finished a unit in the computer lab and moved backwards to 12. Homework is from unit9 (worksheet) skip 4 5 and 6!

Spring Break Note

Thank you to all who have been using this as a tool in keeping current, taking responsibility is very important to making the grade!

Both classes: When we get back from break, I will be assigning a project that should take on the order of 2 weeks to complete. You will be afforded only minimal class time to work on this, instead relying on you to take time at home in the evenings and during weekends. This project requires you to do some research on populations, make predictions based upon information, and report findings to the group. You will be required to type your information, submit a copy electronically (email/cd/flash drive), and present a portion to the class. Visual aid is strongly suggested, and you will be required to site your sources of all information for full credit. More information will come in class, but I am always available to discuss the project with you during the morning, or after school tutoring sessions, or by email: runderwood2@pghboe.net

I hope you are having a wonderful break, I leave you with a picture of a young (11 week old) mathematician for inspiration.

Algebra II - The final piece of the test was a response to the definition of a logarithm -- if you read the prompt, breathe, read it again, think about it, and read it again, you should have had no problem answering. Don't get all worried when math class has words instead of numbers!! Picture the last time you got a paycheck, or bought something at the mall, you probably thought yourself through the numbers by explaining the situation (which required words and numbers), but you didn't freak out then, did you?

There is a short quick worksheet for homework -- realize that the first side is MOSTLY explanation/examples and NOT problems you have to do (the answers are supplied below). Also, you do not have to create the equations for the growth/decay functions, just tell me which they are. Have a great break, but don't count your chickens before the hatch.

Algebra I - Cognitive tutor day -- hopefully you made it to lesson 32 for full credit this quarter, if not, you can always work on the tutor outside of class to make sure you are keeping up! Congratulations to Samantha and Paige for completing 32. Great job ladies!

No new homework, but watch for info on an upcoming project.

Algebra II - Today was a graph day, and people are still struggling with Domain/Range of functions. Realize that the domain is the set of all x's that can be put into the function to receive a valid answer -- if your calculator says ERROR in the table under y1, that value is NOT in the domain. The range is the set of all y's or answers that you get out -- often you can look at your graph and realize it is or is not continuing through the positive/negative numbers or zero.
No new homework, finish the take home test...


Algebra I - Test was today, and you can finish it at home. I encourage you to write out possible combinations or permutations when solving those types of problems. Writing out even a small set of the possible answers in an ordered list can help tremendously.
Homework is to finish the test.

Algebra 2 - Quiz was today, hopefully everyone thought it was easy --don't freak out from word problems!!! Homework is to look over log functions and properties, plus p. 513 quiz, 1-20


Algebra 1 - We worked with stem and leaf plots, and looked at box and whisker plots. Homework was a worksheet from class. I was unable to post the PDF of the worksheet, but will figure it out soon!
