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.

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.

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.

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.

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