These games are meant to reinforce basic addition and subtraction facts through 20. Each game incorporates two facts that equal the same sum or difference. Sums/differences are listed twice on each board. Students try to make four in a row vertically, horizontally, or diagonally (some even like to do four corners). If four in a row is not possible, the student with the most markers wins! Each game comes with 1 game board, 16 game cards, and 20 markers.
