Description
Practicing determining the THIRD step in mental subtraction and click it! This fantastic game doesn't ask students to subtract, but it asks students to think about what they should subtract. 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: 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!
