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.

Players take turns adding shapes made of three squares to a grid. They try to fit their shapes on the grid in a way that blocks the other player.

In this activity, young learners will explore shapes, textures, and geometries using household materials.

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°.

In this great hands-on activity, learners use patterns to make a teepee from newspaper that they sit inside.

In this calculus activity, learners use a classic problem of geometrical probability to find an important mathematical constant (pi).

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

In this math lesson, learners arrange pattern blocks to create tessellations and to explore geometric patterns. Learners first explore making patterns with a variety of pattern blocks.

In this game, learners are stuck in a right turn only world! Learners take turns rolling a die and moving their game pieces along the lines of a grid to get "home," by only making right turns.

As learners play this challenging strategy game, they build understanding of area and perimeter. On each turn, a player draws a line between two dots next to each other on the grid.

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

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

This strategy game has simple rules but can be a challenge. Players start with an empty hexagonal grid. On each turn, a player initials one empty hexagon on the grid.

As learners play this game, they develop logic, geometry, and spatial visualization skills. Players start out with an empty hexagonal grid.

In this activity, learners use geometry to predict the shape of carbon. Learners twist and attach chenille stem pieces that represent bonds between different carbon atoms.

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.
