Give your class the "write" stuff! In this lesson, your students will learn to master combining sentences using sentences with the same subjects or predicates.

Drawing on various problem solving techniques, students will challenge themselves to solve word problems involving three whole numbers. Problem solving, critical thinking, and real life applications? This lesson has it all.

Your students will have a blast thinking about polygons and making these paintings inspired by Wassily Kandinsky!

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

Shape up your students' understanding of geometrical attributes with this hands-on math lesson. Students will gain a better understanding of how to describe a shape by the number of edges and vertices it has, rather than by its name.

Give your students a head start on 3D shapes with this lesson that has them use their observational skills to identify what differentiates the shapes.

Introduce your class to composite shapes with this lesson that reviews geometric shapes and makes use of tangram puzzles. This lesson will give your students a strong base for learning geometry later on in their school careers.

Teach your students about the shapes that make up the world around them with this lesson that has them identify shapes in the classroom and in drawn scenes.

In this lesson, your students will break down composite figures to identify 2-D shapes that make them. Students will put together 2-D shapes to create a composite shape.

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

Students will work hard to build shapes with straws in this hands-on lesson about the defining attributes of triangles. Use alone or with Know Your Shapes.

In this lesson, your students will play "I Spy" to identify 3-D shapes. They will use language to describe the shapes and be able to compare them easily.

Explore 3-D shapes with your students and help them identify and talk about the relevant attributes of three-dimensional shapes, all while using real-world examples! Use this as a stand-alone lesson or alongside the Shape Models lesson.

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!

Get ready to see green! In this lesson, students get hands-on experience creating trees and then measuring to compare the trees.

Students will learn out how to partition a rectangle using by partitioning shapes with rows and columns.

Get the dice out and help students get targeted practice in adding 1 and 10! In this fun place value game, students keep adding to try to get to a maximum score of 100. But be careful. If you go over 100 you’re out!
