There are four Themes. They are the rest of your child’s assignments. They include science, history, and bible daily as well as weekly art, music, and PE/health lessons. Every day there is one of the weekly courses.
Theme 1 is biology and ancient history.
Theme 2 is zoology and early American history.
Theme 3 is earth science and geology and cultures.
Theme 4 is physics and chemistry along with modern history.
The music and art for each theme corresponds with the history in many instances.
There are just two levels for the Themes. Level 1-4 are the lower level lessons. Level 5-8 are the higher level of lessons. They can be considered the elementary and middle school levels. I set it up that way so that all of your children can be studying the same thing at the same time. They may all be learning about pyramids or bones, or whatever, on the same day, but they most often will have different readings or videos to do so.
