The Activity Book contains both the instructor pages (first half) and the Student Pages (perforated second half).
Our copyright allows you to reproduce the Student Pages as you wish for use within your own family. If you have more than one child, or if you prefer to keep your Activity Book intact, you can purchase the Student Pages in looseleaf format or in PDF format and print copies for each child.
Some parents/instructors are comfortable teaching from a laptop or tablet, so they purchase the Activity Book in PDF format and print the Student Pages as they go along.
Classroom instructors may purchase a license to reproduce the Student Pages.
