How Can Teachers Use It?

CK-12's Geometry module includes a wide variety of resources, including reading passages, pre- and post-read activities, assessments, videos, study aids, and Web links. Topic coverage is extremely comprehensive, including Definitions and Introductions to Proof, Pythagorean Theorem, Perimeter, Circumference, Area, and a whole host of others. As with other CK-12 math modules, topics are further broken down into subtopics, so it's easy to search for resources that align to specific lessons you're teaching.

No matter what topic you're teaching, you can have your students complete the Read activities as part of a lesson wrap-up. They can work individually or in collaborative groups, but it's probably best to also review and discuss the Guided Practice answers as a whole class. The videos make for great whole-class instructional support -- you can pause to address specific concerns or address potential problem areas in more detail.
