Geometry

Overview

Your student will be learning:

how to identify, describe, and sort 2-dimensional and 3-dimensional shapes based on their attributes (the number of edges, sides, faces, etc.).
how to make target shapes by joining two, three, or four 2-dimensional shapes.

Example: Use two trapezoids to make a hexagon, six triangles to make a hexagon, two rhombuses and two triangles to make a hexagon, etc.

Videos
