This centers-based lesson on modeling fractions is designed for two-days of 45-minute lessons or one-day of a 90-minute lesson block. The lesson provides differentiated instruction using the H.O.P. Centers Framework. H.O.P. stands for Hands-On, Open-Ended, and Practice which are the themes for each of the three centers in the framework. Lesson structure is designed using brain research principles. In this lesson students will learn how to model fractions to convert between improper fractions and mixed numbers with a short engaging lesson, hands-on activity in which students use play doh to create different fraction circles, practice writing about a word problem using fractions, and engage in tiered practice of the concept.
