In this activity, learners get hands-on with geometry by making a polyhedron kitty sculpture.

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

How do you measure a bubble when it's floating? You can't really, but in this activity, learners can measure the diameter of the ring of suds a bubble leaves on a flat surface.

In this activity, learners arrange triangles together to make patterns to create paper quilts. Learners experiment with arranging the triangles in different ways to make various designs.

In this activity, learners will build a honeycomb. Learners will investigate how the shape of the honeycomb develops. Activity includes step-by-step instructions and extension ideas.

In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

In this activity, learners manipulate paper to build original 3-dimensional sculptures. Appropriate for any age, learners can use fingers to tear, crumple, or fold, and if available, scissors to cut.

In this two-part math lesson, learners investigate problems that foster algebraic thinking across content strands. In the first part, learners explore even and odd numbers linked to quilts.

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

In this activity (on pages 55-66 of PDF), learners fold paper into origami shapes and then combine several identical shapes into a three-dimensional structure.

In this math activity, learners observe and sketch cracking patterns in pavement.

In this activity, learners slide shapes to create unusual tiled patterns.

In this art/science/math activity, young learners are introduced to the concept of symmetry in nature.

In this activity, learners cutout a set of shape finder templates to explore shapes in the world around them.

In this activity about sleep rhythms (on page 21 of the PDF), learners will collect data about their own sleep cycles and use a fraction wheel to examine their data.

In this activity, learners investigate how geometry plays a role in perspective.

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

In this math activity, learners will create a scale diagram of their backyard or other outdoor area on graph paper.

Build a house you can fit inside, using cardboard tubes.

In this geometry activity, learners explore networks painted on playgrounds, such as a four square court, and draw their own.
