  • Math Lines In this game, race to pair numbers that add up to a target sum. Before your child plays, review the pairs of numbers that add up to the target sum. You might even look at different ways to make the number using game pieces, marbles, or pennies.

Multiplication

  • Times Square  This game provides practice with multiplication facts as players race to be the first to get 4 products in a row on the game board. Use "guest pass" to enter game list and play against the computer.
