Division 0 - 12, Math Flash Cards

I bought these for my 3rd grader who is learning division facts this year. What I like about these cards: the numbers are large and easy to read, and each card has a small print answer on the back. The main drawback about this set is that each card has division facts on both sides which make it difficult to sort this set by "fact families". My daughter's curriculum introduces one fact family at a time, so I would spent a good chunk of time flipping the cards front to back, fishing out all the facts within a family for her to study. In order to sort facts by families, I would prefer to have the facts on one side only. Also, the image of box on the website makes it look like these cards contain only numbers on the face. However, the set I received have cartoon drawings of kids in various poses and activities on half of the cards. This can be distracting to a student. My daughter is learning her facts just fine with these, but the description of the product didn't explain the facts are on both sides of each card.
