What’s the Difference Between the Guides?

Both the Dimensions Math® Teacher’s Guide and Home Instructor’s Guide work well in a hybrid learning environment. The key difference lies in how the lessons are written: the Home Instructor’s Guide is designed for one-on-one instruction, while the Teacher’s Guide is structured for group settings.
There are also some differences in format.
You can explore sample pages of both guides to compare layouts.
