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.
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°.
Solidly PlatonicAdd to list Details
In this activity, learners follow simple directions to explore and create platonic solids.
Geometry: Tiling the PlazaAdd to list Details
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.
Build A DomeAdd to list Details
In this activity, learners explore the structural strength of triangles by creating their own free-standing geodesic dome out of plastic straws.
Patterns and Relationships: Struts 'n StuffAdd to list Details
In this math lesson, learners identify the relationship between the number of sides in a regular polygon and the number of struts needed to make each polygon rigid.
Looking Through the Algebraic LensAdd to list Details
In this two-part math lesson, learners investigate problems that foster algebraic thinking across content strands. In the first part, learners explore even and odd numbers linked to quilts.
Shape DetectivesAdd to list Details
In this activity, learners cutout a set of shape finder templates to explore shapes in the world around them.
String ShapesAdd to list Details
In this activity, learners work together to make polygons (many-sided shapes) with string. Learners sit on the floor and hold onto a piece of string slid between their thumbs and index fingers.
