Introducing Division of Integers

Today in math class we explored the division of integers using what we have learned about the relationship between division in multiplication found in fact families.  This allowed us to create algorithms for dividing integers.

We worked through 3.3 and collaborated as a class to explore various fact families with both positive and negative numbers.  During this process we found that multiplication is commutative (3x2=2x3) and that division is not commutative (3/2 is not equal to 2/3).

Here is a link to the notes from class today: Problem 3.3 Notes <-- For those of you who did not get a chance to finish in class I have put the answers on the notes for you.

Also, a friendly reminder that the homework for tonight is ACE #7-8 on pg. 69 and #33 on pg. 77.
