The simple act of rolling dice and creating a problem is more engaging than practice examples in a textbook. On Target! is designed to practice addition and subtraction (though it could certainly be modified for any operation or concept), with a bit of problem solving and strategy thrown in. The game begins by rolling three 0-9 dice to create a 3-digit number. This will be the target number. Players will select 6 cards from the deck (face cards removed). The cards are then arranged to create two 3-digit numbers, so that either the sum of the numbers or their difference is as close to the target as possible. Play continues for eight rounds, or for a set amount of time. The player with the least difference (i.e. totaled from each round) is the winner.
I played a variation of On Target! with a class of 4th graders today. In the estimation version of the game, the target is a multiple of 10 (though it could easily be 100 or 1000!). Players select 4 cards from the deck and arrange them to create two 2-digit numbers, so that either the estimated sum or difference is as close to the target as possible.
