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.

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

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.

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!

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

Students will begin to calculate volume of different rectangular prisms using base ten cubes and then transition to using the formula V = L x W x H. Students will then practice using the legendary fifth grade activity, Cootie Catchers.

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.

Go to any length to test your students' understanding of perimeter calculations. Students will use their understanding of the perimeter of rectangular shapes to create rectangles that have different side measurements but equal perimeters.

Students will use their hands to mold clay into shapes, then divide those shapes into equal and unequal quarters.

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

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.
