High School Geometry Curriculum

The Time4Learning Geometry curriculum is one of five math courses offered at the high school level. Students can expect to see various concepts being covered including points, lines, and planes, logic and reasoning, angles, slopes, triangles, polygons, circles, volume, area,  and more.

Geometry is taught using a combination of multimedia lessons, instructional videos, worksheets, quizzes, tests and both online and offline projects.

Members often use this page as a resource for more detailed planning, as a guide to help select activities using the activity finder, or to compare our curriculum with state standards and homeschooling laws.
