Owl and Mouse Educational Software has boatloads of free educational games and activities good for a wide range of ages. My favorite part of their site is the geography – free on-line map puzzles and interactive maps. Whether you’re learning the 50 United States and their capitals or you’re trying to memorize all the countries in Africa, these are a fantastic way to learn and review. Also available on the site are activities to learn letter sounds, and games to learn about medieval life (Castles, Shields, Knights, and Heraldry). Have fun!
