2D shapes are all around us! In this lesson students will explore the properties of four different shapes—triangles, circles, rectangles, and squares! They will learn that they can find these shapes anywhere in the world around us.

Students will explore geometric shapes by creating a painting of a trapezoid.

Students will love composing shapes using tangrams in this hands-on lesson! Use this plan alone or as a support lesson plan for the Tangrams: An Ancient Chinese Puzzle lesson plan.

Sorting takes on a new challenge for students in this activity which engages their critical thinking skills. As students determine defining attributes, they’ll figure out what makes a shape a shape!

Look all around! We can find 2D shapes inside 3D shapes wherever we go! In this lesson, students will sort shapes and recognize the 2D components of common 3D shapes.

In this lesson, students engage in interesting hands-on activities that help them discover the properties of parallel, perpendicular, and intersecting lines. Your little mathematicians will have a blast as they learn about geometry.

With this activity, students will identify shapes, build 3-D shapes, and practice describing shapes with a partner.

Use this lesson to introduce the concepts of capacity and volume with young learners. This hands on lesson can be used as a scaffolded pre-lesson to Capacity Comparison.

Perpendicular, intersect, parallel! In this lesson, students work in teams to complete a Frayer Model on each of these terms to become masters of geometry vocabulary. Teach this lesson on its own or as support to the lesson What's My Line?

Geometry is a core of mathematics in the early years. Help students recognize and draw shapes given specific attributes such as the number of corners and sides. This lesson can be a stand-alone activity of paired with 2-D Shapes!
