 I created this partner game to give my students practice estimating sums and differences.  This game supports sol 3.3a, estimate and determine the sum or difference of two whole numbers.  Before playing the game, students should have already studied rounding.    In this game, students take turns flipping over four cards and rounding the number.  Then, they add the rounded numbers to find the sum or subtract the rounded numbers to find the difference.
