Teachers can use this interactive tool to help students build a conceptual understanding of what it means to multiply with fractions. The tool includes word problems and paraphrase applications of the word problems, visual models, and equations. It can be used to model the use of multiplication to find the product for both "groups of" and "parts of" problems. This page includes a video demonstration of the tool and sample lessons from the Conceptua curriculum. Free registration is required to use the tool. A paid subscription is necessary to access full curriculum and allow full student use.
