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?

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.

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.

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

Practice calculating perimeter with the placement of carnival-themed games with given rectangular dimensions. Your students will use grid paper to determine the location of all the games they choose to make the perfect carnival.

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

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.

Use a scavenger hunt, art activity, and stickers to help kindergarteners understand shapes and positional language.

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!

Your students will solve and create shape riddles while practicing their knowledge of shape attributes.

Students will use the inverse relationship between multiplication and division to complete an area formula in a real-world situation. Use this lesson on its own or as support for the lesson The Case of the Missing Rectangle Side.

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!

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.

Allow your students to explore the pros and cons of different strategies used to find the area of rectangles. Use this as a stand alone lesson or as a pre-lesson for the Multiplication and Area in the Community Garden lesson.

Give your students some early practice with shapes using this simple lesson. Young learners will have a great time creating shapes using pieces of string.

How do you build spatial reasoning, critical thinking, and problem solving skills while doing something that is fun? With tangrams! In honor of Chinese New Year, this lesson introduces your students to the Chinese puzzle of tangrams.
