Walking Polygons
Source Institutions
In this activity, learners walk the sides and interior angles of various polygons drawn on the playground. As they do so, learners practice rotating clockwise 180° and 360°.
Six Squares: Geometry and Design
Source Institutions
In this activity, learners take a turn contributing a closed figure made of six squares to a large grid; each must be different from all the others on the grid so far.
The Right Fit
Source Institutions
In this math activity, learners trace their hands and estimate the number of beans that can fit into their hand tracings. Then, learners glue the beans to the tracing to test out their estimations.
Needlework Designs
Source Institutions
In this math activity, learners create symmetrical designs for paper models of special blouses known as huipiles.

Toothpick Patterns
Source Institutions
In this hands-on activity, learners use toothpicks to build different triangles and squares and then use the toothpicks to build and solve some tricky shape puzzles.

Shrinking Coin
Source Institutions
In this demonstration, learners attempt to get a large coin through a small hole, the size of a smaller coin.

How to Test The Strength of Shapes
Source Institutions
In this activity, learners explore the strength of different shapes. Fold paper into triangles, squares, and other shapes, then experiment with how much weight they can hold.
