North America Digital
Our 8th unit of year 1 is all about North America! One unit includes a teacher's guide, all your grades from preschool to grade 12 PLUS all your subjects except for math! It's all here!
If you don't mind doing the printing yourself, the digital option is a great value as you will get to reuse the unit in years to come with the freedom to print as many copies as your family needs.
