Symmetry Fold-Overs
Source Institutions
In this math activity, learners experiment with the concept of symmetry.
Dowels and Rubber Bands I
Source Institutions
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!

Gumdrop Dome
Source Institutions
In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.

Rotating String Shapes
Source Institutions
In this group activity, learners make multi-sided polygons with string.

Family Scavenger Hunt
Source Institutions
In this activity, learners will take a walk with their family and incorporate a scavenger hunt. They will explore topics like ABC’s, numbers, colors, and shapes as they search for related items.

Tricky Tangrams
Source Institutions
In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.

Strong Shapes
Source Institutions
Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!

Wet Art
Source Institutions
In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

Tangram Challenge
Source Institutions
In this activity, learners use tangrams ( 7-piece puzzle tiles) to assemble a variety of shapes. Tangrams are ideal for improving spatial reasoning and geometry properties.
Toothpick Patterns
Source Institutions
In this math activity, learners make toothpick designs by following simple patterns.

Shape Stamping
Source Institutions
In this activity, learners will explore two-dimensional shapes that are found in three-dimensional shapes. Learners will explore geometry, design, color and tool use through this activity.

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.

Geometric Solids
Source Institutions
This math activity exposes early learners to a variety of three-dimensional objects. Learners bring geometric solids (everyday objects) from home.
Look Around: Hunt For Sizes, Shapes and Numbers
Source Institutions
In this activity, learners will participate in a scavenger hunt involving sizes, shapes, and numbers. This activity works well with a whole group, individuals, or families.

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.

Building Three-Dimensional (3D) Structures
Source Institutions
In this activity, learners practice drawing 3D structures in two dimensions. Learners draw cube stacks from five different points of view.

Copy Cats
Source Institutions
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.
Hexagon Hunt
Source Institutions
This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

Exploring a Complex Space-Filling Shape
Source Institutions
In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

Party Hat Symmetry
Source Institutions
In this hands-on activity, learners make New Year's Eve party hats out of wrapping paper. Learners use symmetry and measurement to cut out shapes they need to assemble the hats.
