as a father of a 12yo boy, 8yo girl, and 3yo boy, I have some experience here. Anything where he can take apart and reassemble which requires trial and error, and creative new ways of doing things is great. I love Thomas train tracks, legos (yes not duplo, actual legos because my kids never put things in their mouth), Lincoln logs, puzzles. All of that play leads to things like Snap Circuits, etc.
