Children master opposites and build vocabulary skills…with handy, double-sided flash cards that provide learning fun for everyone! On front, each flash card has a photograph labeled with its corresponding word. On back, the card shows the word again and uses it in a sentence that matches the picture on the front. The set includes 56 durable cards—54 flash cards (representing 27 opposite pairs) and 2 activity cards—each with quick-sorting, rounded corners. Cards measure 3 1/8" x 5 1/4".
