> There must be some alternative way I can regularly show him interesting stuff in math. Of course there is, but you need to get creative. Math textbooks are notoriously bad at this, although there are some exception. My tip: use play and riddles. Use characters he could identify with. Like "Han Solo received secret transmission about two magic numbers. If you add them, you get 11. When you subtract one from another, you get 3." Sounds like a very easy riddle, doesn't it? Whereas in fact you can use it as a gentle introduction to systems of equations with two variables which becomes clear as you increase the numbers so the kid can't solve them by trial and error easily. "And now I can show you the secret way of solving it!" The key is that you (1) always need do present a concept with a concrete application, (2) the application has to be relevant and interesting to the kid, (3) just like with all games, it must not be too easy nor too difficult.
