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.

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?

This is a fun lesson for your students to learn shapes while playing an engaging matching game. Your students will also get to practice their fine motor skills in this lesson.

Shapes, shapes everywhere! In this lesson, your students will identify shapes and differentiate between the geometrical figures. They will also learn about sides and angles in every shape.

Get your students up and moving as they learn the basics of geometry. Your competitive students will love this game and put their new skills to the test with a worksheet.

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.

It’s magic! In this lesson, students will “magically” move shapes together to form new shapes. Clay and toothpicks equal hands-on fun! Tangram challenges are provided for those students who need that little extra challenge.

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!

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!

In this lesson, your students will become familiar with shapes by identifying them in real life. Your students will love identifying how many sides shapes have by drawing and counting them!

Strengthen your students' understanding of cubic units and volume! They'll solve a realistic problem and explain key ideas about volume. Use this lesson on its own or use it as support for the lesson Volume and a Building.
