Easy conjugation game that can take any amount of time you want (up to 20 minutes, for most groups).
I like this game because it requires both skill (conjugating) and luck (rolling high numbers), so kids who struggle aren't automatically discouraged if they play against a "high flyer student"--they could still win!
First page is the game board, second page is the rules.
