Abstract:

This article addressed 4 questions: what do we want students to understand in terms of fraction multiplication? What models build meaning for fraction multiplication? How should the models be sequenced? What role should the algorithm play in students’ understanding of fraction multiplication? We addressed these questions within a RNP research and curriculum development grant. We share with you our insights into teaching fraction multiplication, with a specific emphasis on the impact that two different models—using a number line and folding paper—had on students’ understanding and how we sequenced these models for instruction.
