Geometry Lesson Plans

1. 3-D Drawing and Geometry- In this geometry unit you will see some different types of 3-D drawings, and learn how to do these drawings yourself. You will also explore many interesting careers that use these techniques, from architecture to movies.
2. Buckyballs- Students wondering why we study about polyhedral can find one reason by looking through the information in the links to Buckyballs.
3. Crystals: Crystallography & Systems- Students studying polyhedral enjoy seeing the structures as they occur in the real world. Crystalline structures can be categorized into seven crystal systems.
4. Designs with Circles- In the Islamic culture the circle is a unit of measure. The circle is the basis for the organization of space. It is a starting point in architecture, poetry, music and even calligraphy.

1. Discovering Pi- Many students tend to memorize, without understanding, formulas that we use in geometry or other mathematical areas. This particular activity allows students to discover why pi works in solving problems dealing with finding circumference.
2. Dueling Pinwheels- Dazzle your students with this so-cool animated introductory exercise.
3. EggMath- The Shape of an Egg, which includes discussions of surfaces of revolution and methods for drawing ovals in the plane.
4. Euclid's Geometry: History and Practice- This series of interdisciplinary lessons on Euclid's Elements was researched and written by Alex Pearson, a Classicist at The Episcopal Academy in Merion, Pennsylvania.
5. Explain the Change- The lesson will be introduced by reviewing slope as a rate of change as previously discussed in class.
6. Exploring Mathematics Through Quilts-
7. Exploring Geometry on the Sphere- This particular activity allows students to discover that not all geometry is Euclidean.
8. Exploring Similarity Using Scale Drawings- Students will explore properties of similarity using models, measurement, and calculation.
9. Ferris Wheel- Physical devices can be modeled using dynamic geometry. A vital tool for moving objects around in the model are the isometries, or distance-preserving transformations. This model of a Ferris wheel provides a good example.
10. Floor Circles- Students will display a numeral as the area of a rectangle. Students will make as many rectangular Arrangements as possible for each numeral given.
11. Geometric Factoring
12. Geometry Worksheets
13. Introduction to Geometry for Primary Students- These lessons are designed to guide young children through an introduction to geometry. Children will learn to recognize shapes and to create patterns, and will explore spatial relations and symmetry.
14. Magic Squares- Students often believe that "mathematics" was "written" by one person. In these pages you will find that the magic square mathematical game has existed throughout history and in many different parts of the world. Math is all around us and your mind will see it when you're ready!
15. Measuring the Earth- The purpose of this activity is to get students interested and involved in doing science, give them a reason to use some of the math they have learned, and develop a feeling of cooperation in working with people from other schools.
16. No Matter What Shape Your Fractions Are In- Can you name the 4 geometric figures?
17. Polyhedra in the Classroom- . The unit presented here uses the objectives found in Unit 14 of Glencoe's Interactive Mathematics, but the activities have been designed so that students can take extra time on specific mathematical ideas.
18. Studying Polyhedra- Sometimes in mathematics we study ideas that are abstract and difficult to see, but polyhedral can be seen! Crystals are real world examples of polyhedra. The salt you sprinkle on your food is a crystal in the shape of a cube.
19. Tangrams- This unit for grades 4 through 6 uses tangrams to compute the area of polygons without formulas. In the process of doing so, the terms congruent and similar are introduced.
20. Tantalizing Tessellations- This unit integrates math with subjects such as language arts and arts education. Throughout our activities we have asked the students to respond to the concepts of tessellations. They will write definitions and assess how well their groups worked together.
21. Tell Time with your Feet- In this activity, each person will measure his/her height with his/her own feet (NOT the feet on a ruler). It has been found that everyone is about 6 of their own feet tall.
22. Tessellation Tutorials- Tutorials and templates for making your own tessellations.
23. The Apple Barrel Quilt Unit- This unit will provide a brief framework of ideas that could then be tailored to the students' input and their interests.
24. Three-Dimensional Objects- Students will be able to identify objects that are in the shapes of rectangular prism, cylinder, and oval.
25. Three-Dimensional Shapes- In this activity, students will identify shapes that architects use to build houses. Students will then explore these shapes by building a model of their "dream" home.
