Geometry Scavenger Hunt

Scavenger HuntYou can find geometric shapes everywhere! Practice observation skills and notice examples of geometric shapes in this scavenger hunt, and then sketch and write about each shape.

Walking Polygons

polygonsIn this activity, you’ll walk the sides and interior angles of various polygons drawn on the playground.

Playground Patterns of Cracks

pavement cracksPaved surfaces sometimes form cracks due to stress from objects embedded in the surface, or due to stress created by expansion or contraction. In this activity, you’ll observe and sketch cracking patterns.

Tiny Pants Photo Challenge

tiny pantsWhat would your friend look like in “tiny pants”? Using a simple trick of perspective, you can dress your friends in tiny cutout clothing.

Walk a Math Trail

math trailsGet outside and explore geometry (and other math) all around you. A math trail is a walk with various stops where you look at math in the world around you, and ask questions about it.



Geometry Activities for Educators

These hands-on activities will help spark students’ interest in geometry. They're designed for classroom use but can also be done by families or other groups. ESPAÑOL indicates activities that are available in Spanish.

Outdoor Activities for Educators

This set of activities is written for a class, after school, or other group to do on a playground. They can easily be adapted to be done by families, however, and they can be done at other outdoor locations. Physical exercise and the gamelike nature of the activities make learning geometry fun.
