If you have 2 students that will be doing 5th grade math, this is a really great program, and these books are lovely.

My children did not want to use this curriculum, which made me sad.

This set includes two student books and one teacher book, providing a complete educational resource for math concepts. Published in 2016 by BJU Press, the workbook-style format is perfect for homeschooling and classroom use. Focused on mathematics and applied mathematics, this textbook is written in English and is suitable for beginner and intermediate levels. With a strong emphasis on math education in the United States, this product is a valuable tool for students looking to enhance their math skills.

The student books have all of the pages, but the first section has been pulled out of both of them.  It appears they were pulled out of one to reproduce them for the other. from page 91 and beyond all pages are still intact in the student books.

I have taken photos to show how some of the pages are just set inside the book.

 Teacher book is in perfect condition
