Students use the coordinate plane to investigate how reflections affect geometric shapes. Can be used by the student, but is also a great lesson plan idea for teachers.

In this activity, students find the area and the perimeter for several geometric shapes. They also determine the surface area and volume of spheres.

Why can we find geometric shapes in the night sky? How can we know that at least two people in London have exactly the same number of hairs on their head? And why can patterns be found in just about any text - even Vanilla Ice lyrics?...

The designs found in Moroccan weaving and textiles often come from things of everyday life or from basic geometric shapes. Given on this site are seven examples of common designs for you to explore and enjoy.

Students must show that they can calculate basic distances, areas and volumes for simple geometric shapes.

This tutorial will show you how using formulas can help you solve problems. Include formulas for various geometric shapes and steps showing how to use them.

Students use both area and perimeter to work with geometric shapes.

Use this lesson plan to help students learn about cylinders. Students will be creating cylinders, and comparing them and their capacity. This engaging, hands-on lesson will hold student interest and be very beneficial to student learning.
