Curriki is coming out with a free Geometry course that will be available in September. The course is modular, so it can be used to supplement an existing Geometry program, or serve as the main curriculum.

The course is to be project-based, emphasizing real-world examples, such as using Geometry to create architectural designs for an apartment or house, or designing a floor plan that maximizes open space and natural light.

The Geometry units will feature interactives and videos as part of the instructional materials, and will be structured based on the six Common Core High School Geometry topics: Congruence; Similarity, Right Triangles, & Trigonometry; Circles; Expressing Geometric Properties with Equations; Geometric Measurement & Dimension; and Modeling with Geometry.

Again,  this course will not be available until September, but you can sign up to participate in the beta launch here. They will notify you when the course becomes available.

Curriki also has a free Algebra 1 course that was launched last September.
