Do you have an older teen who is learning about the U.S. Constitution? The Liberty Classroom has a free series of videos you may want to check out. They have a full year’s class called U.S. Constitutional History: The Non-P.C. Version. It is a paid course, but they have the first 15 lectures available to watch completely FREE! That is a lot of learning for free. Go here to check out the free U.S. Constitution Lectures from Liberty Classroom.
