Solving Ratio and Proportional Problems on the Cartesian Coordinate Plane

Anne M. Collins

• 6–8 Session

CANCELLED: Thursday, October 22, 2015 | 12:30-1:30 p.m.

This live presentation in Atlantic City has been cancelled. Presentation slides are available below.

Modeling ratio, rate, and proportion using multiple representations is the focus. Double number lines, tape diagrams, and the Cartesian coordinate plane are models for proportional reasoning. Computation with fractions will also be modeled on the Cartesian coordinate plane, as it is an effective representation for visual learners or for remediation.
