To create equivalent fractions you multiply the _____________ and _____________ by the same number.
numerator and denominator
1/8 + 5/6 + 1/6
Use the associative property to group the numbers we should add first. Be careful to only use the associative property- no other property.
1/8 + (5/6 + 1/6)
Regroup 5 3/24
4 27/24

5/7 + ( 2/9 + 4/7) = 5/7 + (4/7 + 2/9)
What property was used here?
commutative

Does this expression require regrouping/renaming?
NOPE! I know this because I created equivalent fractions before I determined if I had to regroup or not. Ms. Cyr's laser eyes engrained this idea into my soul. Now I'll never forget. It would be 7 16/24- 6 15/24 (Pride point to anyone who got this right -for being a good listener!)

The commutative property tells us that we can change the order of addends (flip flop) and it doesn't affect the outcome of our answer. The associative property tells us that we can group addends using ___________ (indicating to add them _____).
parentheses; first
