Flip- Flop Strategy

Yesterday and today I was teaching a math concept--know as the commutative property to the older students. We call it the flip-flop property in 1st-2nd grade though. Anyways, it states that when you change the order of numbers that you add or multiply, you get the same answer. For example: 2+3=5 and 3+2=5

1st and 2nd grade did adding and 3th-8th did a multiplication example on their flip=flops.

I explained that when you take your numbers you flip them around and that's how it's called the "flip-flop" property!
