This card sort can be used repeatedly to introduce and review the concepts of fractions, equivalent fractions, and comparing fractions. Students should work with a partner to compete the activity. Begin by having students simply match the fraction representations with the visual models. You might remove the more difficult cards to scaffold the learning for students. Repeat the activity and increase the rigor by having students compare using the <, >, and = cards. This is also a great activity to use in math centers.
