What’s Goin’ On In Room 133

POST UPDATED ON JAN 14th (Thu)

Just to keep you abreast, Colleaugues, here’s the homework that we laid out this week.

Math 7 – MONDAY:  You had page 153, Ques 1 – 4.   TUESDAY:  Your assignment was to Read and Study Section 4-2 (Solving Addition and Subtraction Equations) on pages 156-158.  Then do even-numbered questions 4 – 24.  THURSDAY:  Textbook page 162, Ques 14, 15 and 16.

Enriched Math – MONDAY:  You had page 21, Ques 49 – 52.  TUESDAY:  your assignment was to Read and Study Sec 1-4 (Properties) on pages 23-27.  Then do even-numbered questions 14 – 34.  THURSDAY:  Textbook page 31, even numbered questions 30 – 40.

You all know that Writing Prompt #9 is due this Friday in your Math Journal.  Points will be LOST for not having one by now.  Rock on Collegues!

Always a good thing, Colleagues, especially when it comes to your grades.  I do hope that it’s a happy time in your household right now with the arrival of your first report card.  If it is, then, congratulations!  Hope you have a great weekend.  But if it’s not, then it’s Making Up Time for you!  Especially if you did not do too well on the Properties Test – the results of which, by the way, are NOT reflected on your report card.  They’ll be starting off your next Interim. 

So if you want to make things right, or if you really want some extra credit for next time, I strongly suggest you take a run at the latest Opportunity for Greatness linked below.   Rock on, Colleagues!

Make Up Assignment for 7.3 Properties Test 091106

Click on the link below to view the slides we used to fill out the Interactive Notes on the Identity and Inverse Properties and the Multiplicative Property of Zero.  TEST ON THURSDAY!!! 

7 3 Properties of Operations 1 (Numbers)

Read page 30 – 31.   Study Examples, Key Concepts and Vocabulary.  Do Questions 1 – 3 on page 32 in your Math Journal.  (DUE ON WED, OCT 28th)

Read your text, pages 23 thru 25.  Study Examples, Key Concepts and Vocabulary.  Do Questions 1 – 3 on page 26 in your Math Journal.

Commutative and associative, both for addtition and multiplication.  Additive identity, multiplicative identity and then there’s the multiplicative property of zero…whew!  As you saw, all of these are nothing more than names for “number rules” that you have been using all these years.  

3 + 4 = 4 + 3 and 3 x 4 = 4 x 3 …gee whiz!

2 + 3 + 4 = (2 + 3) + 4 = 2 + (3 + 4) and (2 x 3) x 4 = 2 x (3 x 4), right?

any number + 0 = the same number (a + 0 = a)

any number x 1 = the same number (a x 1 = a)

any number x 0 = zero! (a x 0 = 0)

Piece of cake! Now start looking at that Distributive property and take a run at page 101, questions 12-23 (do 2 in each column), questions 26-49 (do 3 in each column) AND do either 47, 48 OR 49.  

Essayons!

You’ll find discussion of our exponents and properties in Lessons 4-2, 1-4, 3-1 and 3-2.  Yeah, we have to skip around the book a bit to keep everything in order, but that’s ok.  As long as we take our knowledge of parentheses, exponents and always remember to Please Excuse My Dear Aunt Suzie (PEMDAS), we will soon emerge in good standing on our good properties – the Commutative, the Associative and last but not least, the all-important Distributive Properties!

We’ve looked at expressions, order of operations and even substituted a few variables along the way.  We are now able to evaulate algebraic expressions if we are given a value for the variable (such as “if x=6, then what is 3x?).  Now it’s time to apply some of that knowledge using exponents (”We answer to a higher power!”) and properties (”Get off my land, y’ varmint!”).  Seriously, take a look at Lesson 4-2 on pages 153 thru 155.  We’ll do homework on Monday from page 155, ques 8 thru 23.
