Algebra 1 Spring Semester

Week 17 HW February 13/14

Resources will be added to the resource page soon. Note, this week’s HW is longer than normal. You have two weeks to complete it.

Week 17 - Do the Chp 9 Quiz which I handed to you in class. Stop at the line which says stop. Open binder and calculator but no book/internet or other people. Just your notes and good brain.

Smart Studying

• Work your multiplication mastery plan. Some of you may be ready to move onto the 11s & 12s. Get your parent’s signature verifying you studied multiplication facts for 10 minutes every day 5 days a week. 6th day is a bonus point.

• Review your class notes, KIN, and any video notes. As you review your notes ANNOTATE them. Make drawings and add notes to help you remember and understand.

GREENIE CLASSWORK… we typically start this in class and you finish what’s left over at home. This is usually review.

(This is Math 8 for those of you who are going to integrated math programs in HS. For everyone else it is review as well as a preview of some geometry.)

Are the following pages complete? Answers to Greenie work are on a button above “Greene Answer Keys”

• REVIEW Page 13 Exponents and Roots: multiplying, dividing exponents, and powers of powers

• REVIEW Page 14 Exponents and Roots: Scientific Notation

• NEW page 35 Measurement and Geometry: Volume of Pyramids and Cones - (finish) evens

Textbook Homework

Take home chp 9.1-9.3 quiz. Open HW/CW/Binder, unlimited time, calculator okay. Closed textbook.

PH 4.1-4.2 Check Point Quiz #1 pg. 195 —all of this is SQUARE work for bonus HW points. DO 2-8 EVENS & 9-10

PH 4.3 Percent Proportion & Equations…

• CW PH 197-199 read and do examples

• HW Check understanding pg. 197-199 #1-6

PH 4-4 Percent of Change… review from last year (we’re skipping % error problems)

• Read pg. 204-206. Do you remember the mnemonic device you created last year? If not, make a new one to remember the formula. Add this formula to your IMPS.

• Watch and take notes on this Math Antics Percent Change video 

• CW pg 204 Ex 1 & 2

• HW Check understanding 1-2 on pages 204-5

PH 4-5… Probability:  Theoretical, Experimental and Prediction (Newish but not really— you just haven’t had HW on this yet)

• CW PH 211-213 Ex 1-4 — pay attention to “or” = another favorable outcome

• Re-read examples in section 4.5 and highlighted vocab and formulas to your IMPS (probability, outcome, even, sample space, theoretical probability = favorable outcomes/possible outcomes, impossible even, certain event, complement of an event)

• Optional review videos:

  • Theoretical and Experimental Probability Math Antics Probability

  • Odds in favor and odds against: What are odds?

    •  Favorable : Unfavorable Video with Mario’s Math Tutoring

    • How to figure out odds if you’re given the odds “Odds with Shaq”

• HW PH 214 #3, 5, 11, 13, 17, 198 21, SQUARE 29 & 31 as well as MR 55-69 odds PENTAGON pg. 217 do checkpoint quiz 1-9 odds

PH 9-3 & 9-4 & 9-7 Special Cases (difference of squares and squares of binomials)

• DIFFERENCE OF SQUARES: Watch and take notes

  • Math is visual Difference of Squares video https://www.youtube.com/watch?v=3X2Pp2FOwCY

  • Slightly harder Difference of Squares and another short video with slightly harder problems

    1. 1st Look for a GFC (greatest common factor)

    2. Look for a difference of squares OR a squares of binomials

    3. You might need to simplify and them combine like terms

• PERFECT SQUARE TRINOMIALS ARE REALLY JUST SQUARES OF BINOMIALS: Watch and take notes

  • Mario factors a few problems

• CW p 492 Ex #3 (BASIC a =1) abc, 4 (a doesn’t equal 1) abc, 5 (pull out a GCF first) abc

• HW: Read pg. 490-492 then add these special cases to your IMPS

• HW pg 493 #1-6 all, 13-31 odds

PH 9-5… Introduction to Regular Trinomials x² + bx +c

• CW comparing diamond problems to y =  x² + bx +c. Deducing a mental shortcut. SB HO pg 323-324, 339-340

• HW: Show a parent or older sibling how the Diamond Product & Sum Puzzle is the way you can factor ax² + bx +c (if a=1)

• HW: Finish HO SB pg 340.

• HW: Read pg. 481 Add y = x² + bx +c ² is a regular trinomial to your IMPS.

• PREVIEW VIDEO: DIAMOND & BOX METHOD Using the diamond/box method with Mario (3 minutes)
