    Product Description

    Fractions and other rational numbers are challenging topics to teach as well as learn. What does it take for students to make sense of rational numbers in their myriad forms, such as fractions, ratios, rates, percentages, and decimals? For instance, understanding fractions requires part-whole thinking, including partitioning, iterating (the process of making copies of a unit fraction to make a whole), and unitizing (identifying the unit and the whole). Making sense of ratios also requires part-part thinking and proportional reasoning involving multiplicative rather than additive comparisons between two quantities. As teachers, we want to focus on how to foster these kinds of complex and sophisticated ways of thinking among our students. The Editorial Panel of Mathematics Teaching in the Middle School wants to know your thoughts on what can be done to improve students’ rational number sense.
