Some of the most productive ways often involve the use of representations that anchor studentsâ€™ experiences in the quantities being learned. Although almost all representations have their limitations, they also provide opportunities to support students in pressing their understanding of rational numbers. In this article, I share an activity motivated by a discussion that occurred during one of my seventh-grade classes. We used a hundredths diagram, in which the area of the large square represented 1 unit. rv:
