Monday Sept 13th.


Today:
1) We warmed up with mental math (a 1/2 sheet with addition on one side, multiplication on the other).

2) Ms. Gesner explained the "checks" motivation system for the class. (In short - do good things, get checks, redeem checks for good things, repeat).

3) Quick review of "Rainbow Factoring" versus "Tree Factoring"
Rainbow - Factors of 24 = 1,2,3,4,6,8,12,24 (use an arc to connect 1 and 24, 2 and 12, 3 and 8, 4 and 6 and you'll have a rainbow)
Tree - Used to get Prime factors. 48 will always be 2x2x2x2x3, no matter how you draw the tree.

4) We began the correction of Yellow Pretest.

HOMEWORK:
Finish Mental Math Halfsheet.
