FEATURES 
The Leap from Patterns to Formulas Darin Beigie Geometric problems help students progress from predicting numerical patterns to expressing algebraic generalizations. 
Bring the Pythagorean Theorem “Full Circle” Christine C. Benson and Cheryl G. Malm Different representations for relationships help students visualize mathematical concepts rather than just memorize formulas.

Tell a Piecewise Story Nathalie Sinclair and Alayne Armstrong By focusing on slope and using dynamic software, students develop the ability to describe functions in a geometry context.

Fold in Origami and Unfold Math Joseph Georgeson Students fold exciting shapes to explore how changes in one dimension affect measurements in another.

Virtual Data Collection for Real Understanding S. Asli ÖzgünKoca and Thomas G. Edwards Extend a wellknown circleexploration activity using technology to connect geometry and algebra. 
Seven pages of activity sheets

Dine on Rich Functional Examples 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.
