Today he was writing out the numbers. After looking over his work I asked what a certain number was. It was supposed to be a 10, but looked more like an "H". He answered, "It's a 10 in Hebrew!"
He continued writing out the numbers again and was counting them out loud. He got to the number 40 and stopped for some commentary. He said, "Forty is a great age. You know why? "Cause you can shoot a machine gun!"
Life with Jack is certainly full of surprises....even in the middle of a math lesson!
