Grade 2 Geometry Lessons

Use these lessons to name plane figures, count sides and corners, and compare common two-dimensional shapes.

Corners and Sides of Plane Figures

What Grade 2 geometry covers

Grade 2 geometry helps students name plane figures, count straight sides, find corners, and compare shapes by their visible parts.

Sides and corners come first

Before students use longer geometry words, they need to see that a shape can have straight sides, curved boundaries, corners, or no corners at all.

Start with plane figures

The first Grade 2 geometry lesson in this path explains the corners and sides of common plane figures such as circles, ovals, triangles, rectangles, and polygons.
