Geometric problems help students progress from predicting numerical patterns to expressing algebraic generalizations.
Christine C. Benson and Cheryl G. Malm
Different representations for relationships help students visualize mathematical concepts rather than just memorize formulas.
Nathalie Sinclair and Alayne Armstrong
By focusing on slope and using dynamic software, students develop the ability to describe functions in a geometry context.
Joseph Georgeson
Students fold exciting shapes to explore how changes in one dimension affect measurements in another.
S. Asli Özgün-Koca and Thomas G. Edwards
Extend a well-known circle-exploration activity using technology to connect geometry and algebra.
Rebecca R. Robichaux and Paulette R. Rodrigue
Starting with the Dinner Table problem, and extending to other geometric examples, students become familiar with patterns and functions as well as graphing concepts.
