Geometry: Let's Face It
Source Institutions
In this math lesson, learners identify, describe, and construct the five regular polyhedra.
Make a Tikiville Teepee
Source Institutions
In this great hands-on activity, learners use patterns to make a teepee from newspaper that they sit inside.
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.
Throwing Pi
Source Institutions
In this calculus activity, learners use a classic problem of geometrical probability to find an important mathematical constant (pi).
Exploring Tessellations (Grades 3-5)
Source Institutions
In this activity, learners repeat patterns in two and three dimensions to create tessellations.
The Right Fit
Source Institutions
In this math activity, learners trace their hands and estimate the number of beans that can fit into their hand tracings. Then, learners glue the beans to the tracing to test out their estimations.
Tri, Tri Again
Source Institutions
Learners estimate how many small triangles will fill a larger shape. Then they use a triangle stamp (or stencil made from a file folder) to fill the larger shape with triangles.
Build A Dome
Source Institutions
In this activity, learners explore the structural strength of triangles by creating their own free-standing geodesic dome out of plastic straws.
Make an Animation
Source Institutions
In this activity, learners make a device called a phenakistoscope, which displays a continuously looping animation consisting of images drawn onto a spinning disc.
Carbon Configurations
Source Institutions
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.
Make A Map for A Treasure Hunt
Source Institutions
In this activity, learners will explore how maps can provide information about a place and help us find our way from one location to another.
Bubble Sculpting
Source Institutions
In this activity, learners develop spatial reasoning skills as they blow bubbles and observe what happens when the bubbles connect.
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.
Exploring Tessellations (Grades K-2)
Source Institutions
In this activity, learners repeat patterns in two and three dimensions to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.
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.
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.
