Too many posts! Too many links! If you go through my Fun Learning Stuff archives, you find oodles and boodles of links to online games and things. But that’s a lot to wade through. Allow me to spare you the wading.
Free online word games:
Babble (a combination of Boggle and Scrabble)
Eight Letters in Search of a Word (both this one and Word Poker are "see how many words you can make out of these eight letters" games)
Scrabulous (online Scrabble, and yes, it is fabulous)
iSketch (like Pictionary) (beware the public rooms—create your own private room and invite friends)
History, math & science:
BBC History Games (a whole bunch of fun stuff here)
Ancient Greece game at Snaith Primary
Absurd Math (Jane’s favorite)
Test your reaction time with the sheep game
Music & art:
