This game for 2 - 4 players helps students to hone their skills when adding and subtracting 2 digit numbers with and without regrouping. Students work together to find the sums or differences, then mark the answer off on individual game boards. The first person to get 4 in a row wins. To make the game more challenging (and this is the part that my students love!) there are cards in the deck that allow one player to add or remove markers of their choice.
The game includes instructions, game boards for 4 players,36 addition and subtraction cards, 6 add or take away a marker cards, and an answer key for checking all the equations.
