How to Learn Basic Shapes by Making a Shape Mobile
Source Institutions
In this activity, caregivers and young learners work together to craft and talk about shapes and relative positions of such shapes by creating a mobile.
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.

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.
