Solid Shapes

This lesson plan provides teachers with a lesson on 3-D objects. Students will learn to name and compare different solids as they look for them in their everyday lives.

Solids and Polygons

This worksheet allows students to practice recognizing and naming 2D and 3D shapes.

Polygon Questions

This worksheet allows students to practice recognizing the properties of polygons and identifying what is and what isn't a polygon.

I've Seen That Shape Before

In this lesson, students will learn about the properties of various geometric shapes, including cubes, cones, spheres, rectangular prisms, and triangular prisms. Students will work with solid geometric figures to learn about the corners, faces, and edges of each shape.

Deriving the Formula for the Area of a Circle

This lesson plan displays the transition between the area of squares and rectangles to that of circles. Your students will gain a solid understanding of why the formula for the area of a circle is much different from that of simpler shapes.

Kindergarten Math: Orientation and Spatial Sense

This lesson plan provides Kindergarten teachers with introductory lessons on elementary geometry and how to teach students about orientation, shapes, symmetry, outlines of shapes, and models of solids.
