Teachers and parents send us more "thank you" letters over this innovative question and answer card series than any items we’ve ever developed. Why? It’s because the art is child-friendly, the who/what/when/where/why questions are easy to understand, and kids of all ages love to play card games! That’s a winning combination. In each deck, you get 28 match-up pairs of questions/answers (56 total), all 2½" x 3½", and stored in a sturdy tin.
