Attributes of Polygons: Stretchy Shapes
Fourth graders use dancing methodology in a polygon and shape activity. For this shape and dance lesson, 4th graders discuss shapes in dance, math, and everyday life. Students use dancing activities to recognize and analyze shapes.
Curated OER
Shape Tool
Students explore various polygons and examine how shapes can be manipulated in a variety of ways. In this shape tool lesson, students identify geometric shapes in two dimensions. Students identify and draw one line of symmetry in a...
Curated OER
Compare 2-D Shapes
Second graders explore and analyze plane shapes. For this plane shapes lesson, 2nd graders evaluate shape attributes to classify shapes correctly. Students work in groups to create different shapes.

Tour + Workshop = DESIGN: Shape
Ask elementary pupils to explore shapes in everyday objects. They will discuss the elements of design and describe the shapes they see in visual images. Students will then design and "build" a new 3D shape. Finally they will show and...
Curated OER
Tin-Foil Twinkles
Learners compare and discuss characteristics and properties of 2- and 3-dimensional shapes. They construct 3-dimensional paper star figures, imaginatively customizing them with art tools and craft materials. Students analyze their...

Poly-Mania
This hands-on activity takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...
Curated OER
Third Grade Geometry
Third graders describe 2D and 3D shapes. In this geometry lesson, 3rd graders watch a PowerPoint presentation showing the terms used when analyzing shapes: vertex, edge, angle, side, and face. They compare shapes to see what they have in...
Curated OER
Shape & Form
Students analyze the difference between shape and form. They identify, explain and use the basic elements of design and determine that forms are three-dimensional and shapes are two-dimensional. They sketch it on their paper and then...
Curated OER
Building Big and Strong
Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.
