Mental Math Strategy - Division

Completing division questions quickly and accurately is important. This mental math strategy can help your students improve their efficiency and provides another strategy for them to draw upon. 

In my class, I teach my students to use multiplication when dividing. Instead of dividing the number from left to right, work from right to left and multiply. 

Example 1: 36 ÷ 9 = ___ Work from right to left. 9 x ___ = 36. The answer is 4.

Example 2: 48 ÷ 8 = ___ Work from right to left. 8 x ___ = 48. The answer is 6.

Example 3: 63 ÷ 7 = ___ Work from right to left. 7 x ___ = 63. The answer is 9.

It’s a simple strategy that some students do naturally. If you teach this explicitly to your class and practice daily, you’ll see their progress in no time! The mental math worksheets above will provide your students the practice they need when working on this division strategy! If you need more mental math strategies, check out Third Space Learning.
