Math Open Reference
This site covers different types of Geometry including plane, coordinate, and solid. It was constructed by a software designer from Silicon Valley. It is described as a reference for both educators and students and looks to move beyond the standard Geometry textbook. A Java plug-in is required to run the site. It can be used on a SmartBoard as well as just using it on a desktop or laptop computer. Many of the pages rely on click and drag interface, but does allow the student to discover the concept as opposed to reading it in a book, or simply trying to memorize rules.

Euclid’s Elements
When it comes to Geometry, it doesn’t get any more fundamental than this book. It was the Geometry text book for a couple of millennia and the Clay Institute of Mathematics have provided all 13 books digitally. There is the useful side-by-side translation page with links that take one to the pertinent postulate, theorem, or definition. Also, you can look at and zoom in on a digital replication of the actual text. It is difficult to find this text in print with all 13 books together, much less to get enough for a whole class.

Geometry in the Real World
This is a great reference to geometry in the real world. It is brought to you by Quickie Math. It provides students with applications of geometric shapes in modern day architecture and vehicles. Students will be able to see a concrete example for abstract ideas. They will be able to see how people in real professions apply basic concepts from the high school classroom.

Learning Geometry
This is a website designed for both students and teachers who need additional help or resources to teach or learn geometry. It is divided up into sections according to subject. Each section is broken into subsections that contain instruction, example problems with solutions, interactive problems, and videos. In addition, it also provides insight on how to teach various subjects and hands on materials that can be used to help students learn. In my opinion this site could be used as a valuable tool in the computer lab to help students better learn the material and become more familiar with technology. I believe it could also be a valuable second resource for the geometry teacher to draw from.

Geometry, Geometry!
This site provides crucial definitions to geometric terms. Feel free to explore in order to get a better understanding of these terms.

It uses up-to-date baseball stats to answer the question, “Who is the greatest baseball hitter of all time?” It is incredibly flexible, so if you don’t want to use the pre-made list, you can change it to encompass the players that the teacher, or the student, feels better using. Additionally, you can make the list entirely of players whose careers are completed to allow for full evaluation. This WebQuest is perfectly suited for a Statistics class, but could be used in Algebra as well.

Trilingual Packaging Dilemma
In this WebQuest, students take the role of packaging designers, using only triangles to create a package that meets specific criteria. Students work in teams, but are responsible for their own creation as well. The author recommends a two week time period for this activity, which is too much class time to devote on a block schedule. The reason for the long time scale it the construction phase, so it would make sense to spend one class periods performing the research, another later on for the teams to strategize, and then a third for students to make their presentations.
