Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.

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°.

Use geometry, a ruler, and a steady hand to create these amazing unfurling paper folds!

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

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

Learners determine the surface area and volume of two identical boxes, and then figure out the dimensions of a cubical box with the same volume.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

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

In this math lesson, learners follow step-by-step directions for making tangram pieces out of folded and torn paper. First, learners read "Grandfather Tang's Story" by Ann Tompert.

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

In this activity, learners use cooperation and logical thinking to find solutions to network problems on the playground.

In this activity, learners design unique tiles and make repeating patterns to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.

In this activity, learners use pattern blocks and mirrors to explore symmetry. Learners work in pairs and build mirror images of each other's designs.

In this math activity, learners build Peppy the dog the best trail and park for running around.

If you have 3-foot dowels and rubber bands, you can can started on this fun and open design challenge. You can make structures big and small: make it so you can fit your parent into it!

In this group activity, learners make multi-sided polygons with string.

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.

Straws and pipe cleaners are terrific materials for building models of pyramids and cubes.

In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.

In this math activity, learners use what they know about shapes to copy a friend's hidden picture. Learners create a design out of pattern blocks and then hide their picture behind a screen.
