On A Roll uses 30-sided alphabet dice (I got mine from Amazon.com) and a board like the one pictured. Students in the center each have their own board. They take turns rolling the die and adding letters to build the words on their game board. The first person to roll all their words is the winner. I copied my boards on cardstock and laminated. Then the kids can use expo erasable markers to wipe away their boards at the end of the game.
