Sam has a fantastic memory and an understanding of how things works. He loves taking toys and trucks apart and reassembling them. But when it comes to counting he got a little muddled. I've heard him counting in French no problem but he has trouble remembering in English. I told him the easiest way was to use his fingers, but he said he needed to see the numbers. Easy peasy - I wrote the numbers on his fingers and 10 minutes later he had got it. Now he can visualize numbers on his fingers when counting.
