What’s Goin’ On In Room 133

Posts Tagged ‘identity’

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

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.
