Description: Three terrific games help students think before they start to subtract and give them thinking about the steps they should complete in their heads! For STEP ONE: Students determine the FIRST step in mental subtraction and click it! It helps students learn to break up larger, two digit numbers into tens and ones in order to subtract mentally; it also provides practice recognizing how much to subtract from the ones' place when there is only one digit being subtracted. 50% of the questions have equations with two-digit numbers being subtracted, and 50% have one-digit numbers. For STEP TWO: Students determine the SECOND step in mental subtraction and click it! It helps students learn to break up larger, two-digit numbers into tens and ones in order to subtract mentally and provides practice recognizing how much to subtract from the ones' place. Please note: Some problems have three steps to solve mentally, and this game focuses on the 2nd step. For STEP THREE: Students determine the THIRD step in mental subtraction and click it! Please note: The subtraction format practiced here is subtraction by tens and then ones. If the subtrahend's ones' place is larger than the minuend's ones' digit, the value of the minuend's is subtracted first. (For example, 35 - 18 = 3 tens -1 tens = 25 - 8 = 25 - 5 = 20 - 3 since 8-5=3 and 20 - 3 =17.) This is taught because these subtraction equations deal with regrouping. Enjoy!
