Canine House of Cards
Source Institutions
This simple construction activity teaches the importance of architectural structure. Learners build and test designs for a paper "doghouse" strong enough to hold the weight of a jumbo dog biscuit.
Loopy Geometry
Source Institutions
Discover geometry by creating shapes from loops of paper. In this activity, paper loops transform to give you totally new structures when you cut them.
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.
Castle Basics
Source Institutions
In this four-day lesson, learners identify three-dimensional forms in castle design, research different parts of the castle with a focus on their uses, and design and enlarge a banner for the great ha
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.
Tessellations
Source Institutions
In this activity, learners will engineer a new shape and use it to create a new pattern with no wasted space.
Paper Folding: Unfurling Geometric Paper Shapes
Source Institutions
Use geometry, a ruler, and a steady hand to create these amazing unfurling paper folds!
Six Squares: Geometry and Design
Source Institutions
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.
Exploring Tessellations (Grades 3-5)
Source Institutions
In this activity, learners repeat patterns in two and three dimensions to create tessellations.
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.
Experimenting with Symmetry
Source Institutions
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.
Cut-Fold-Staple
Source Institutions
In this activity, learners discover how to rotate a flat shape into the third dimension. Learners draw and cut out a shape that has at least one straight edge on an index card.
Making Tangram Pieces by Folding Paper
Source Institutions
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.
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.
Patches the Cat: A Print-and-Build Paper Sculpture Kit
Source Institutions
In this activity, learners get hands-on with geometry by making a polyhedron kitty sculpture.
Paperfolding Polyhedrons
Source Institutions
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.
Making a Translation Tessellation
Source Institutions
In this activity, learners slide shapes to create unusual tiled patterns.
Building Houses: Build a Cardboard Tube House
Source Institutions
Build a house you can fit inside, using cardboard tubes.
Burst a Bubble
Source Institutions
In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.
One-Cut Paper Stars
Source Institutions
Here's a very simple activity if you have paper and scissors: make one cut, unfold, and you have a beautiful star! A great way to learn about polygons and origami mathematics.
