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.
