We have been expanding the idea of commutative property (5+4=9, 4+5=9) and finding how many different ways to come to the sum of 10 (10+0, 9+1, 8+2...). Then, with this list realize that finding a sum of 20 has a similar pattern (20+0, 19+1, 18+2...)
Friday morning we had 18 student so I asked them to generate lists to see how many different ways we could get to 18. We were only able to take 3 pictures because being outside became so fun that no one could agree on what we were doing. It is hard to see the white board, the first picture shows 18+0=18, the second shows two groups of nine students, or 2x9=18. The third is 17-1=18.
My kid loved this creative drill. The girl wouldn't stop talking about it. So brave and brownie point to you Ms. Bond for making learning so much fun!
