How to play:
Before each math class, visit How to Prove It: Guide for Lecturers Bingo and print one copy of this game card for each player, refreshing the page before each print, or have the players print their own bingo cards. These instructions will not be printed. You can also select card only and multiple card versions of this page when playing online, or with a PDA.
Check off each block when you hear these words during the class. When you get five blocks horizontally, vertically, or diagonally, stand up and shout "EUREKA!!!".
