Geometry is one of our favorite subjects. You can't turn around without finding a new way to relate it to the real world. We touch on a wide variety of these in our Geometry textbook, Essential Geometry. You can find more on our free graph theory classroom.

All of the resources we provide for Geometry students are summarized in the tabs below.

Core Curriculum

Essential Geometry is our core geometry textbook, available for purchase from our on demand publisher.

Teaching Geometry is our teaching guide. It's a compendium of resources and teaching suggestions that parallels Essential Geometry. It's also available for purchase from our on demand publisher.

The Teaching Geometry classroom is a free, online copy of the Teaching Geometry textbook. It includes all the material from the book except for problem solutions.

Extended Curriculum

Our free Graph Theory classroom discusses the properties of studies the positive integers, i.e. the numbers 1, 2, 3, 4, ... What sounds like a really simple basis for a full branch of mathematics is actually a complex and diverse subject that is at the heart of modern cryptography.

Teaching Geometry	This classroom is the online version of the teaching guide for our core geometry textbook, Essential Geometry. It contains all of the teaching suggestions in the textbook but does not include the exercise solutions. We made a conscious decision not to include those on the public web site because some parents may not want their students to have access to a complete solutions set.
Graph Theory	Let's say you have a collection of items. What sort of items you ask? The items can be anything. They could be as concrete as a group of students in a classroom or as abstract as the atoms in a complicated molecule. They can be close to home like the intersections in your neighbourhood or as far flung as individual computers connected to the Internet. Some of these items will have connections between them and others won't. Kids in a classroom are connected by their friendships. Atoms are connected by chemical bonds. Intersections are connected by roads. Computers are connected by phone lines. In each example some items were connected and others weren't. Graph theory is the study of these connections.

Essential Geometry is our introductory geometry text. The book is written in clear, easy to read English with detailed, hands-on applications from fields as diverse as ballistics (measuring the angle that produces a maximum distance) and art (tilings and mosaics).

Teaching Geometry is the companion text to Essential Geometry. This isn't your standard "teacher's edition". Rather than being just a copy of the student's version with the answers added, it's intended as a teaching guide. Each section lists teaching suggestions for the corresponding section in the student's text along with supplemental material and complete solutions to every exercise question.
