This mathematics lesson teaches students to interpret division of whole numbers by fractions using visual models. Students begin by drawing and describing fractions using fraction cards. They then work through examples of dividing fractions by whole numbers, such as dividing 3/4 lb of trail mix among 6 friends. Students represent the division problems using number lines and fraction bars divided into equal parts. In exercises, students rewrite division problems as multiplication and model the answers. The lesson aims to help students understand that dividing a fraction by a whole number results in a smaller quotient.
