Fraction Multiplication and Division using Virtual Measurement Models

Session Goals: Explore applets to support conceptual understanding of fraction multiplication using length models. Discuss how these applets can be used with students. (Please bring a web-capable device.)
Note: The applets we use in this session are not the focus - you may find applets that will work better for your classroom. Rather, the focus is on the concepts and how technology can support dynamic aspects of fractions as length.

Session Take-aways: There are connections - and disconnects - between visualizations of fractions using length models: across discrete and continuous unit representation and across the actions of multiplication and division.
