TODAY’S AGENDA Warm-up Review Quiz #1 Talk Finish U1. “Whats My Number” Activity

What’s My Number? DAY 3 REVIEW OF GROUP ROLES – Leader/Reader: reads activity for group & reports group’s responses – Writer/Recorder: write group’s responses on white board – Questioner: ensures all group members are contributing to answering questions; this person will signal for teacher if all are stuck – Supply Runner: retrieves needed supplies & brings group displays to the front of the room

What’s My Number?– DAY 3 Your Task: In groups, read and answer questions # You will have 10 minutes to complete this task.

What’s My Number?– DAY 3 Math Properties Foldable – Commutative Property – Distributive Property – Associative Property – Subtraction Property – Addition Property – Division Property – Multiplicative Property – Identity Property (ADD vs Multiply)

What’s My Number?– DAY 3 Commutative- Switching order on one side of equal sign EX- a+b+c => a+c+b Distributive- Multiplicaton using parenthesis Ex) a(b+c) => ab +ac Associative- Rearrange parenthesis=> same operation EX) a+(b+c) = (a+b)+c

What’s My Number?– DAY 3 Addition- If you add to one side you must add to the other side Ex) if a=b then a+c=b+c Subtraction- If you subtract from one side you must subtract from the other side Ex) if a=b then a-c=b-c Multiplication- If you multiple one side you must multiply the other side Ex) if a=b then a X c=b X c

What’s My Number?– DAY 3 Division- If you divide one side you must divide the other side Ex) if a=b then a/c=b/c Identity (ADD)= Anything plus zero = that # EX) a+0 = a Identity (MULITPLY)- Anything multiplied by 1 will equal that number EX) a X 1= a
