## Customer Reviews

### ⭐⭐ 







  
  
    No answer key!
  

*by C***M on Reviewed in the United States on October 11, 2019*

We love Singapore math for our homeschool.  I was disappointed to find out that this set did not contain the answer key!  I’m not sure how to obtain one either.  I will go back to ordering directly from the My Father’s World page.

### ⭐ 







  
  
    Product came in used condition 😰
  

*by W***  on Reviewed in the United States on June 13, 2020*

The math books themselves are great. However, I was under the impression that they were in new condition when I ordered them. I was disappointed to open the workbook and see at least 20 pages already written in with pen! Nowhere in the description was this described as a used set. I’m disappointed and am going to return it.
