ab: Summary: Students often have difficulty understanding fractions, in
general, and understanding how to multiply fractions, in particular. To
move past this potential problem area, students need to develop a
deeper understanding of multiplication and connect the ideas to
fractions. In this article, the authors share their 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 they sequenced these
models for instruction. (Contains 5 figures.) (ERIC)
