Bests & Worsts Reviews from Amazon

We purchased these cards because they were to have "answers on the back." Yes the answers are on the back, but so is another math problem. The answer is in "fine print" in a corner. The description is misleading. Answers on the back should mean that 7+3 is on one side and 7+3=10 or 10 is on the reverse, not 8+4.. These cards are not conducive to "children checking their answers" as claimed or to dividing up which problems are known since another problem is on the back. Walmart carries similar cards with math problems on both sides and the "answer on the back" like these. Also does not include all math facts to 12. I pulled the +3's and only had about half the facts. I assume the publisher is relying on someone explaining to child that 5+3 and 3+5 both equal 8. The problem is that rather than being able to learn all the +3 facts one has to study a hodge podge and mentally learn two steps 5+3=3+5=8. Very disappointing that this is not spelled out in description, other reviews or on box. I will not be buying other products from this publisher.
