Where they match

How each one plays by grade

Build Your Library runs 4 grades further than The Story of the World. If you want one program to carry the subject for the long haul, plan on leaving The Story of the World around grade 8 and choosing again.

Build Your Library

Grades K-12

History themes rotate by level: world cultures, then Ancient, Middle Ages, Early Modern, Modern, then American history, then world geography and history in the higher grades. Younger levels are parent-led; older students read and work more independently.

The Story of the World

Grades 1-8

The four volumes (Ancient, Medieval, Early Modern, Modern) map onto a four-year elementary history cycle, one volume per year, then repeat at a deeper level in later grades.
