Comparing and Matching

Comparing and Matching

Mathematicians often need to be able to compare numbers that might be expressed in different ways, and use these different representations in calculations. In this feature, we have chosen some games and activities which will challenge you to figure out when quantities are bigger, smaller, or a perfect match.
