PBSKids.org is a great site with games for all age levels. The site has all their favorite shows and characters. From the Sesame Street reading games for toddlers to Cyberchase math games, there's something for everyone. I particularly like the Railroad Repair game. It's a math game that teaches adding decimals. There's also a page about NYC history. The American Museum of Natural History has a site just for kids. Science games teach kids about biodiversity. There's even a game that shows all the wildlife that lives in NYC. The Lego site has some spacial relationship games that any kid can play, but can also be challenging enough that they're fun for grown-ups too. The New York Philharmonic's site has a kids game room where kids learn about music. For older students The New York Public Library hosts HomeworkNYC.org. In addition to loads of information, kids can get homework help from a librarian. Kabooses' funschool site has tons of games and great graphics for children from preschool up. Kids won't even know they're at an educational site. Here's a site where someone has compiled the top 100 educational computer games. Starfall.com has games that take you through all the stages of learning to read.
