This primary probability game is designed to give students a basic understanding of probability while practicing their subtraction skills. The object of the game is to be the first team to move their playing pieces(eight frogs) across the pond on the numbered (from 1-11) lily pads. When the team spins the double spinner and the difference between the two numbers matches a number that has one of their frogs on it, then that frog safely crosses to the other side. Students keep track on a bar graph of the resulting differences so they can revise their strategy halfway through the game. All worksheets for the game are included in PDF format.
