I sure refer to these links quite often. Silly thing is that my son learned to read at a perfectly ordinary age 6. But he was like a human lie decector for Santa, and the Tooth fairy, etc. I wish I could remember more details. Instead of puzzels, he had a computer program that did puzzles by moving the mouse around. I sure don't remember how many pieces they had. He always hated mazes - there's the possible visiual problems for you. That's why I say that any measure of gifteness that your child does well on establishes a floor, not a ceiling.
Love and More Love,
