My son, 6 1/2 first grader, is in a science club and chess club (he's just learning to play chess). They offer these at school, so it makes it easy. At home we do EPGY math, TimezAttack, and ds LOVES the Fastastic Contraption website. We also have the Rightstart Math program and manipulatives at home, and ds will go pull that out and play around with the abacus, geometric shapes, geo board, fraction tables, etc. Is your son into Leggos? They have the Leggo science kits. DS is also really into Greek and Roman mythology, so we read a lot of books about that. He also plays basketball. My son is not very independent, and if we are unable to work with him, he always wants to resort to video game (Wii or DSi), computer games, or television. We try to limit the amount of "electronics time" he has each day, but sometimes it's the only way to get a break. On those days, I try to make sure he's watching something educational, preferably a science program (some of his favorites are Nova, National Geographic, How It's Made, Survivorman, Magic Schoolbus, Junkyard Wars) or playing a game that requres some logic, problem solving, reading, spelling, or math. I love Big Brain Academy on the Wii and ds loves Leggo Starwars on the Wii. I don't mind it becuase he really has to do a lot of problem solving, which is better than passively watching mindless TV.
