From polyhedrons to platonic solids, here is a lesson that will have your classes talking! As an introduction to platonic solids, scholars cut and fold nets to create the three-dimensional solids. They use an interactive component to...

How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

Whether you wrap it or fill it, you're using geometric concepts. Classmates use an interactive approach to learn how to find volume and surface area of cylinders and prisms in the second lesson in a five-part series. The online lesson...

Explore vocabulary related to three-dimensional shapes. An instructional website describes the characteristics of different geometric solids. Learners can use an interactive component to view nets, faces, vertices, and edges of common...

This MathWorld tutorial provides detailed overviews of the concepts and theorems associated with geometry. Most of the Math World sites are extensive and some require higher math knowledge to understand, links to terms and topics are...

This page of Geometry links addresses many of the Geometry expectations in the Ontario K-8 Math curriculum. There are simple sorting exercises for Grade One and Cartesian Graphing tasks for the intermediate grades.

This site is an archive of questions posed by students and the general public about geometry which are responded to by "Dr. Math."

Site provides information and activities on various aspects of geometry, from shapes to patters and symmetry. Make your own tetra puzzle or build an icosahedron in the classroom. Interactive and fun.

Developments in the art of warfare in the late 15th and 16th centuries provided an outlet for geometry as show in this online exhibit.

Joseph A. Montagna gives an introduction to geometry and the life of Pythagoras. There are lesson ideas and teacher/student bibliographies as well.

Dr. Math, responds to a question fro a nineth grade stduent who wants to understand hyperbolic geometry. The Dr. uses descriptive analogies in attempts to unravel why triangles in hyperbolic geometry have less than 180 degrees in them.

This is a site for geometry lovers. Chock-full of puzzles, games, interesting geometry facts, and online activities.

The Math Forum offers an archive of question and answer sessions on circles and how they relate to geometry.

This resource gives many examples of how math and geometry are used by visual artists to create abstract sculpures.

Contains over five hundred Geometry articles, problems, puzzles, and games. Some sites relating to circles are provided within this list.

Mangbetu art shows the use of all four geometric transforms: Reflection, Translation, Rotation, and Scaling. This website will provide you with some cultural background on the Mangbetu and their art. The software will allow you to...

These lessons are designed to guide young children through an introduction to geometry. Children learn to recognize shapes and to create patterns, and explore spatial relations and symmetry. Each activity is aligned to mandated standards.

Math Forum provides a discussion board for geometry topics. The geometry topics are for pre college topics. This site may be found enjoyable for those who like to think about math topics at times other than school.

This Math Forum site contains many mathematical and geometric explanations and proofs of many different topics that have been done using a geometry software called Geometer's Sketchpad. The explanations are very detailed and clear;...

Circle Geometry math for kids contains information for students to learn about terms radius, diameter, circumference, chord, and pi.

A discussion of Christian Huygens' contribution to wave optics, and particularly to our understanding of the reflection and refraction of light. Excellent diagrams and a geometric proof on why the law of reflection is mathematically...

A collection of diagrams that complement Mathematics 8, a Grade 8 Math text, have been posted here. The diagrams were created using The Geometer's Sketchpad,
