These math books are in excellent shape (like new); however, there is not an answer key so would have to just not have one or order the Answer Key on Amazon or Ebay or wherever. Based on the above, even though each set was $200, lets say $20.

3rd grade. In good condition. $10.00

The book is like new. Asking $25.00

Book would be great summer reading or to use for the school year. $10. Like new!!!

The Manual of these sets is an instruction guide for the parent to teach from.  So this is 2nd grade for lst and 2nd semester.  Let’s say $30 total.  Text books are in excellent condition and there is only some wear on the cover of the manuals.
