Summer's back, nice and sunny out! Talk about whatever you like!
This might also be a good thread to share anything fun you found this summer that other APP parents might enjoy too for their kids. Starting it off, I really like DragonBox, which is the best game I've ever seen for teaching algebra, genuinely fun, the puzzles turn out to be the same operations you perform to solve algebra problems. If you like that, you might enjoy SquareLogic, which is a really excellent implementation of the Sudoku-like KenKen game, teaches logic and fast arithmetic operations, addictive and fun. If you have a middle or high school kid, I'd highly recommend Udacity's free Physics 100 class, surprisingly fun, challenging, excellent blend of physics and math, very well done. Oh, and Camp Orkila is great.
