A school day with R

Here is a math problem R's way. His brain will be the death of me as V says. Anyway to those of you who don't know the manipulative's above represent 12-6=6. When asked to explain- well; I'll try to tell it his way. The 3 block was close and he didn't feel like finding a 2 so he used that and then put the 6 block one space from the end so as to start at the 12 mark. Then I guess he just had a 4 block by him so he put that there and said ok need to add 2 more to the four and now I have 6 as the answer. He keeps me on my toes, trying to decide if he is being ornery or just bored. I have discovered if I put my arm around him and keep things moving we both fair a lot better with the school day. Can't wait till I have him through the first grade and he can do more on his own.
