Fall Semester Math 8 Old HW (from year 3 when we did it with Algebra)

this semester is listed with September at top and December at bottom

Chapter 2: Functions 2.1-2.5

We introduced most of this in class during weeks 11 & 12

Read each section intro and examples. Then try 3-5 problems from the section, usually from the Practice and Problem solving section (see which ones have answers in the back of the book). Then take the quizzes— called Ready to Go On— at the end of every two or three sections (I’ve posted photos of quiz answers . Then do some of the review problems from the Study Guide and Review at the end of the chapter.

If you need more practice here are some suggestions.

Chp 2.1 Ordered Pairs Read intro & examples. Recommended problems: p. 52-53: 17, 19, 21, 25, 27,33

He calls method 1 finding an equivalent ratio “scaling it up by a factor of _____”

Chapter 6

Measurement and Geometry A) Circles, Prisms, and Cylinders

Measurement and Geometry 6.1 - 6.4 -all review

A) Circles, Prisms, and Cylinders

B) Pyramids, Cones and Spheres

Read each section intro and examples. Then try 3-5 problems from the section, usually from the practice and problem solving section (see which ones have answers in the back of the book and use the photos I’ve posted with answers). Then take the quizzes at the end of every two or three sections. Then do some of the review problems from the Study Guide and Review at the end of the chapter.

All of this is review from last year— but easier than what we did in McD!

6.1 Circles Circumference = (diameter) (Pi) Area = (Pi)(radius^2). Memorize these formulas

6.2 Volume of Prisms and Cylinders =(Bh)

6.3 Volume of Pyramids & Cones = 1/3Bh

6.4 Volume of Spheres = 4/3(Pi)(r^3) Surface Area of Spheres = 4(Pi)(r^2)

I’m not posting videos on this as it is pretty straight forward. You can easily find videos on these topics if you need them.

Homework all from Math 8 textbook

Building pyramids and rectangular prism to derive volume formula of a pyramid (1/3)Base Area)(h) compared to rectangular prism with a congruent base and heights. (It took three pyramids to fill up the prism, thus the prism is 3 times the volume, making the pyramid 1/3 the volume of the prism.) Building triangles to review the Triangle Sum Theorem (The sum of the angle measures of a triangle is 180). And to see visually why a straight angle is 180 degrees. Interior Angles Chutes and Ladders review game for Math 8 chapter 5 lessons 5.1-5.3 including angle relationships and angle chasing practice (acture, right, obtuse, straight, complementary, and supplementary angles, vertical angles, alternate interior angles, alternate exterior angles, corresponding angles, transversal). New info: Triangle Inequality Theorem (sum of the lengths of any two sides of a triangle is greater than the length of the third side.)

REMEMBER TO SHOW YOUR WORK. Beginning with this assignment, if you don’t show your work the highest grade you can get on the homework is 7/10 (a C-)

This homework is a review of Chp 5.1-5.3 & Chp 3

  1. PENTAGON: Flash cards for angle terminology: Textbook chp 5.1 page 196 & 5.2 page 203 Make flashcards with drawings for angle terminology in the green box on page 196: acute angle, right angle, obtuse, angle, straight angle, complementary angles, supplementary angles & page 203 alternate interior angles, alternate exterior angles, corresponding angles. Include “vertical angles” - those are the congruent angles in the diagram that are the same color on page 202 (angles 1 & 4 are vertical angles, as are angles 2 & 3) which are across the vertex from each other.

  2. Compass work: Do you remember how to use your compass to bisect lines and angles? Read page 201, then do “Try This” # 1-4.

  3. Angle Relationships Chp 5.1 Re-read text and the examples on pages 196-197. For this section (5.1) do problems 13, 15, 21-25 odds, 26, 27. (You don’t need the page numbers to find the problems.)

  4. Parallel & Perpendicular Lines Chp 5.2 Re-read the text and examples on pages 202-203. Do the “Think and Discuss” on page 202 problem #2. Then do problems 11-21 odds, 22, 25

  5. Triangles Chp 5.3 Re-read text and examples on pages 206-208. Do problems 13-35 odds

  6. Exponents & Roots Chp 3. We did Chp 3 at the beginning of first semester so sections 3.3, 3.4, and 3.6 might feel a little rusty. I recommend you re-read the examples on those sections. Study Guide Review pages 146-148 do problems 1-5 all, 7-53 odds, NO CALCULATOR for 55 & 56 (these are yucky problems without a calculator, I know) and 57-73 odds

  7. Watch these videos to prepare you for material in 7.4 and chp 8. Everyone should watch the videos and pause and do the problems when instructed, however you may earn extra credit point by doing the PENTAGON options which is taking at least one note for each video.

After this we have a few sections in chp. 5 which are new, one section in chp 7, and a few in chp. 8 and 9 and we’ll have completed all of Math 8!

HW 2.1 Monday 1/24

All homework is Math 8

Today’s homework is finishing up chapter 5 and 7 of Math 8 and taking a brief quiz on chp 1-2. (I was going to include chp 3 but we didn’t review the 4 chop 3 questions that students had questions about on Monday. So I’m pushing the chp 3 quiz back to next week with chp 4 quiz.)

  2. Systems of Equations 7.4

    • Video: Substitution Method & the Elimination Method: video on using substitution to solve equations with two variables (he also shows you how to do the “elimination” method which we haven’t learned yet)

    • Video: optional video on using the substitution method (solving for one variable and then substitute in or plug in that expression whenever you see that one variable: as is g + f = 30, so f= 30- g, —> plug or sub in (30-g) wherever you see f in the other equation.)

    • Read the examples on pages 318-319. (You may rewatch the systems of equations videos from last Thursday if needed). Do page 320: #1-15 odds, 37

  6. Identify similar and congruent Transformations Chp 5.7 Read examples on page 231-233. Do 1-7 odds. We did not have time to learn this in class so you’ll want to watch the video below and read the examples in the textbook carefully.

Today’s Math 8 homework is finishing up chp 5 rigid transformations, a review of chp 6 important formulas, and starting the first half of chp 8 on graphing lines (with a little bit of chp 7 thrown into the mix too). Included are videos to reinforce concepts we’ve just learned or to preview coming concepts in Math 8. Everyone should watch the videos and pause and do the problems when instructed, however you may earn extra credit point by doing the PENTAGON option which is taking at least one note for each video.

Next Monday we will have a take home quiz on chp 3 & 4. You can look over your greenie homework on those chapters and bring any questions you have to class on Monday. You can, if you want to, write down any example problems or definitions that you want to have ready for the chp 3 or 4 test (suggestion: write the steps for finding square root of integers down.)

Take notes in preparation for the chp 7 & chp 8 take home quiz next Monday. Put post-it notes on HW problems or classwork that will help you. You might want to have notes on these concepts from chap 7 as well as your notes from chp 8:

  • 7. 2 Solving equations containing fractions (clearing fractions by multiplying both sides by a LCD lowest common denominator. You have work in Greenie about this too.) 7.2 page 305

  • 7.3 Systems of Equations examples on page 318-319, word problem example on page 320 #25 and page 321 #26

MATH 8 TEXTBOOK

Chp 8 Study Guide Review: page 376-378.

  • Define all the vocabulary words (on your paper or flash cards).

  • Do problems 4, 8, 10, 18, 19, 22, 26, 28, 32, 34, 35 (11 problems) For kicks, look at 38 and use what you know about opposites to figure out something special/unusual about how those two lines intersect without lifting a pencil.

  • Take A FEW notes on the following topics to prepare for your chp 8 test in a week and a half on March 24th:

    • 8.1 What does linear mean? How do you identify a constant rate of change? pg 8.1-8.2

    • 8.2 find the slope of a line given two points. What does positive slope look like (see page 347), negative slope, zero slope, undefined slope?

    • 8.3 Use slope-intercept form to find the slope and y -intercept, write an equation for a line in slope intercept form which passes through two given points

    • 8.4 Point-slope form— write an equation given a slope and a point, use point slope form to solve a word problem like problem 18 on page 358 (Answer: y-2344 = 0.05x. 2719 ft above sea level)

    • 8.5 Direct Variation y=kz or y=mx +0 — it always passes through the origin review example 1, 2, 3

    • 8.6 Solving Systems of equations by graphing— when might there be no solution to a system? (they never intersect), when might their be infinite solutions (they are the same line!) Remember, an answer to a systems of equations when graphing is a point
