Are the answers for Primary Common Core Workbooks found in the Home Instructor’s Guides and Teacher’s Guides?
Yes, with fully worked solutions for many of the problems. The Home Instructor’s Guides and Teacher’s Guides have answers for both the Textbooks and Workbooks. They also include lesson notes and suggestions. If you only want answers to the Workbook and Textbook problems, you can get the Answer Key Booklets (there’s one for Grades 1–3 and one for Grades 4–5).
We don’t recommend using the Workbooks by themselves as you and your student will miss most of the core material, explanations, exercises, and teaching notes.
