ab: From the text: Teachers have found many different ways to support students
who are learning about rational numbers. 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.
