That's a great question. I have an autistic nephew who is 11. He is very bright and high functioning. I thought about teaching him chess. My other nephew is 4 and I'm contemplating teaching him in a year or so.
I was planning on finding an age appropriate book to guide me. I was hoping to teach the rules of the game and how the pieces move...but then move on to simple tactical puzzles and mating patterns...and try to keep it fun.
I too am interested in what the strong players on here think about teaching children, because I don't really know all the good child appropriate methods.
My son is 5 and pretty advanced for his age. He is asking me to teach him chess but I'm afraid that even though he's advanced he will get bored and lose interest. Any suggestions? I had been thinking about that game "No Stress Chess" because I have heard that it is a great beginner's game.
