Query: Good Quality = Good Math Practice

I really like this flashcard set, and I just recommended them to a friend. The box is sturdy; the cards are sturdy and have rounded corners so they don't get dog-eared. The numbers are big and clear, and the money and clocks are colorful and fun. My daughter needed extra help in Math, and as each challenge arose we had cards for the subject at hand. Don't feel that age 8 is the cutoff for the usefulness of these cards, because I've found the Multiplication and Division sets handy for review in 4th grade, too.
