What's So Special about 11?

Activity Overview

Students will compute multiples of numbers in search of patterns. As a class, they'll discover patterns in multiples of 9; then they'll do the same with patterns in multiples of 11. They will then practice writing the rule for 11, both verbally and algebraically, to summarize the discovered pattern.
