The Boxes Go Mobile
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.
Geometry and Spatial Relations: Mirror, MirrorAdd to list Details
In this math lesson, learners use hinged mirrors to discover that regular polygons are composed of triangles tessellating around a center point.
Fill It Up
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.
Walking PolygonsAdd to list Details
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°.
Canine House of Cards
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.
In this activity (on pages 41-47 of PDF), learners explore tesselating geometric patterns (repeated shapes, similar to the art of M.C. Escher).
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.
Geometry: Let's Face ItAdd to list Details
In this math lesson, learners identify, describe, and construct the five regular polyhedra.
Make a Tikiville Teepee
In this great hands-on activity, learners use patterns to make a teepee from newspaper that they sit inside.
Beyond Dominoes: PolyominoesAdd to list Details
In this activity, learners add squares to paper dominoes to make polyominoes.
Pyramids and Triangles
Straws and pipe cleaners are terrific materials for building models of pyramids and cubes.
Exploring a Complex Space-Filling ShapeAdd to list Details
In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.
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
Great Openings: Slots, 35 Sense, and Hole In One
These three short activities challenge groups to fit objects through paper and index cards: "Slots" presents the challenge for one learner to figure out which objects fit through a hole cut by another
Party Hat SymmetryAdd to list Details
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.
In this activity, learners will engineer a new shape and use it to create a new pattern with no wasted space.
Crazy ShapesAdd to list Details
In this activity, learners cut a shape into two equal sized pieces and use their knowledge of geometry and space to prove that the two parts are equal.
Geometry and Algebra: The Future Flight Equation
In this activity, learners discover how NASA engineers develop experimental aircraft.
This math activity exposes early learners to a variety of three-dimensional objects. Learners bring geometric solids (everyday objects) from home.
