I LOVE MATH DICE GAMES :) I teach Place value in direct instruction and then use this as a center or station to give them hands on practice time. It could also be used as an "I'm finished! Now what??" All you really need are some dice for students to roll to get their numbers and some paper to record their answers.
No prep for you! Save it, print it, give it to them! PS. Mine are glued in a file folder and laminated but that just for long term use :)
