Billy Bear's Online Games
From preschool to sixth grade, Funschool.com is a cornucopia of grade-specific activities. All are Java-based, so have the same browser requirements as Billy Bear (see above). At the bottom of each activity screen are buttons to play another scenario of the same game, to restart the current game, or return to the grade-level game listings. Learning these will help you get around. My favorite preschool game is Fishing for Numbers, where the player matches numbers to sets of fish. For older kids, I like the geography game "Where in the world?"
"Here's lots of games for you to play, to keep you entertained all day." From the Cat's Concentration game to Green Eggs and Ham picture scramble, Dr. Seuss fans will find plenty to crow about. My don't-miss-it pick of the day is the Shockwave "Hooray for Diffendoofer Day!" game. It is based on the newest Seuss book, written by Jack Prelutsky, inspired by work Dr. Seuss left incomplete at the time of death in 1991.
