Race to 100

Students take turns rolling the dice and placing the rod with the sum of the dice rolled on the 1-100 chart. Only the 11 and 12 may be split up into 2 separate bars. The player places the last piece to cover up all the numbers is the winner. If no winning move can be made, the player who placed the last bar is the winner.
