Each puzzle features one simple three- or four-letter vocabulary word, as well as a full-color illustration that matches the word in question; from OWL and LOG to CRAB and BIRD, your kids will pick up new spelling skills as they play. Designed with little ones in mind, each puzzle is self-correcting, which makes it easier for kids to puzzle out the one right answer. Each set of Spelling Puzzle Cards comes in a sturdy reusable box that doubles as a storage container when play time is done.
