Cool Math Tricks

We discovered an article posted five years ago and thought it worthwhile to share. The article reveals ten easy arithmetic tricks.

We know many teachers do not like parents teaching their kids tricks, but once students have demonstrated conceptual understanding, learning tricks makes math so much more fun.

In our lesson M1.2 Divisibility Rules we provide some “tricks” for helping students learn if a number is divisible by another number, which sure helps them when identifying factors. In this clip we illustrate the rules for determining if a number is divisible by 3, 6, and 9.

(A part of the lesson on rules for division with the autopauses deleted.)

Tell us in the comment section if you know any other arithmetic tricks. We would love to know what they are and we’re sure other teachers would too.
