In this hands on lesson, students create squares with different fraction pieces while building their knowledge of adding fractions with different denominators.

Which number doesn't belong? This lesson requires students to think critically as they determine which number is not a factor of a particular number. Teach it on its own or as support for the lesson Factors Over the Rainbow.
