227 Productive Failure 3

Misconception:

My initial response to this word problem was that it was an add to addend unknown word problem. However, after going back, I realize that not only is this incorrect, but it is not even the correct terminology for any word problem. The add to options are: Add to result unknown, Add to change unknown, and add to start unkown. The addend unkown would have to be either a put together addend unknown or take apart addend unknown. The mistake I made on this problem was combining two different views. Once writing out the problem as 3+__=9, I was able to pretty clearly see that it was an add to change unknown word problem since we were given the number Kyla started with (3), and the resulting number she wanted to get at (9).
