Children learn to recognize six different coins and calculate total values…with handy, double-sided flash cards that provide learning fun for everyone! On front, each flash card has a set of photographic coins. On back, the card shows the matching value in number and word form, plus an addition problem that shows how the value was calculated. The set includes 56 durable cards—52 flash cards and 4 activity/information cards—each with quick-sorting, rounded corners. Cards measure 3 1/8" x 5 1/4".
