Let’s Play Math ~ It’s Important

There are several reasons that it is important for students to 'play math.' First, it's more fun than sweating over 'drill and kill' math worksheets. Next, everyone learns better when they are relaxed and having fun. Also, playing around with numbers, relationships, and ideas gives students a sense of ownership. Finally, messing around with numbers and mathematical ideas creates a fantastic context for skill practice.

Why is 20% of 50 the same as 50% of 20?

The order of factors in multiplication doesn’t change the product. Encourage students to expand their understanding of the commutative property of multiplication to include percents. Even though the commutative property doesn’t apply to division and there is division in calculating percentages, x% of y will always equal y% of x. The swap always works and can be used to make mental calculations of percentages even easier.
