Week 5 HW— October 2/3

No classes next week— that’s fall break— so you have two weeks to do this homework.

There is MORE homework than in a typical week. This is because we have a truncated semester (14 weeks versus 16 or 18 weeks, so we need to do more in less time. But the trade off is that we get more and longer breaks).

Prentice Hall Algebra 1 HW - calculators okay

 Concepts: Linear Equations, Exponents, Motion problems, transforming formulas, adding and sub.  Polynomials & Intro to slope.

Other Tasks:

• GPO: Have parents sign your Grade Print Out (GPO)

• Print out a new table of contents form

• Print out additional HW self-assessment forms

• Optional: You may want to print out some of the coordinate plane work paper too

PH Chp 1 Practice Test- Learning from our mistakes. Redo missed problems from Practice Test - Chp 1

Fix the problems you missed. Write down what your error was (sign error? misunderstood concept? arthimetic error? skipped a step? Forgot vocab? Just didn’t know how to do it?) Attempt it first by looking at the examples in the textbook. Chp 1 TEST SOLUTIONS ARE HERE

THEN Do 5 problems for each problem you missed on the test so that you understand those types of problems. You’ll notice that the test solutions pdf has an answer page which lists exactly what section and example matches the test problem and what HW problems are suitable to practice that skill/concept.

See Algebra resource page under chapter 1 for ANSWERS to all chp 1 problems (for your self-selected practice problems which you need more practice on )

PH 2-5 D=RT Motion in the Same Direction Problems …. (1 problem) We’ll take a break from these after this week and revisit them at the end of year.

HW pg 105-109 Reread Example 3. Watch or rewatch one of the videos below. Then do this D=RT Same Motion“Dirt” problem: pg. 108 #10 — a chart may help you organize your information. (PENTAGON students did this last week. PENTAGON try #21 instead)

See Algebra resource page under chapter 2 for ANSWERS

Video options (from last week)

• A —Traveling in the same direction video from My Math Source

• B - another video example Mr. Kumar’s explanation of how to figure out how to define the variables is really good. (8 minutes)

• C -Traveling in the same direction problem video with Mario - similar to example 2 on page 168 of Orange textbook (Alg 1 Structures and Methods) (often the distance both objects travel is the

PH 2-6 Transforming Formulas & Deducing Geometric formulas (20 problems)

HW pg 111-115 Reread Examples 1-4.Then do the Check understanding#1-4 following each example. Also do pg 113-114#1-8, 17-28, 41 SQUARE also do 44, PENTAGON also do 45 & 46

See Algebra resource page under chapter 2 for ANSWERS

PH 2-6 Extension Deducing Geometric formulas (9 problems)

HW pg 116-117 Read these examples on both pages. Then do Exercises #1-4, 6, 9-11, 14 (Calculator okay!)

See Algebra resource page under chapter 2 for ANSWERS

PH 2-7 Measures of Central Tendency (5 problems)

HW pg 118-121 Read these examples. Then do the Check Understanding problems for each example: #1-5.

VIDEO: Watch one of the first two videos on stem and leaf plots

• review 3 minute video by MySecretMathTutor

• Stem and leaf plot video -3 minutes by Moo Moo Math and Science

• OPTIONAL More advanced stem and leaf plot 13 minute video

PH 6-1 Slope and Slope Intercept

 HW pg 282-288 Read the examples. Do Pg 286-288 #1, 3, 8, 22, ,23, 28, 29, 40

See Algebra resource page under chapter 6 for ANSWERS

• CW SB Graph Linear Equation using xy chart or table (review)

• CW SB 157, 160 – solve for y first to get the equation in slope intercept form y = mx +b or use and xy table

• CW SB 163-4

• UPDATE— we’re changing these to work for next week: CW SB 165-66 odds & CW SB 167 & 168

PH 6-2 Slope Intercept Form

This is a review from last year for most students.

HW pg 291-295. First take notes on the videos below to reinforce the work we did in class and to remind you of what you studied last year. After taking notes, reread the examples on the pages listed for PH 6-2.. Then do the check understanding problems for each example #1-5.

Take notes on these videos (I’d take my notes on graph paper):

• Equation of a line, slope intercept form, functions, perpendicular lines & horizontal lines Math Antics Basics of Linear Functions

• How to graph a line when you have an equation in y = mx + b or slope-intercept form. WATCH this video.

• Mario’s Math Tutoring on equation of the horizontal and vertical lines

• VIDEOS FROM LAST WEEK— IF YOU ALREADY TOOK NOTES ON THESE, YOU CAN REWATCH W/O NOTES OR SKIP ENTIRELY.

  • Math Antics Slope and Distance of a line (slope = RISE / RUN or change in y over change in x or )

  • How to calculate slope. Richard reminds us what slope is and how to find it (10 minutes). https://www.youtube.com/watch?v=5z6IduhkeF0 (take notes for PENTAGON extra credit points)

  • Richard walks us through positive and negative slopes, slope of a horizontal line is zero (y=some number), vertical line has an undefined slope, steepness of slope, what does a line with a slope of 1 look like? (10 minutes) https://www.youtube.com/watch?v=Nl0AAmARm18

PH 9-1 Adding and subtracting polynomials and degrees of monomials (4 problems)

 HW pg 457-60. Re-read the examples #1-4. HW p. 459 #28, 29, 31, 32

Optional Videos:

• How to add and subtract Polynomial Expressions Organic Chemistry Tutor

• What’s this degree nonsense? Organic Chemistry Tutor (don’t fret about this part. Just remember to make the term with the highest exponent first or the “leading term”).

See Algebra resource page under chapter 9 for ANSWERS

PH 8-1 Intro to Zero & Negative Exponents (8 problems)

 HW pg 394 Do the investigation problems 1-4

If you haven’t already finished the SB handout 40-42 please do that now (I think you already did this) Answer keys are available in class.

See Algebra resource page under chapter 8 for ANSWERS

Chp 2 Review and Practice Test (27 problems— we had about 30 minutes in class to start this) Note you’ll also be tested on chp 1 material but this assignment just reviews the chp 2, STUDY FOR THE TEST.

• Measures of Central Tendency,

• solving multi-step equations including ones with no solution or identities,

• transforming formulas to solve for one variable

• Consecutive Integer problems

HW pg 125-127 #1-9, 29-30, 45-47, 52-53, 55, 57, 60, 61, 68-71. Also do standardized test prep on pg 129 #5, 6, 8
