Match these wooden puzzle pairs to make mastering numbers as easy as 1-2-3. Groups of objects illustrate numbers 1-20, and the puzzles are self-correcting—each piece has only one match that fits—so children can play independently and learn at the same time. These wooden number puzzles are an exceptional way for parents and older kids to engage and interact with kids. Parents can play multiple entertaining games such as story time, pick the picture, guesstimating, the grab bag game, color recognition, a memory game, number recognition, and so much more. Our number puzzles are great for helping kids ages 4 and up learn matching and counting skills. For easy cleanup and convenient storage, this children’s number puzzles set can be stored in the included wooden storage box with slide-in lid. The Melissa and Doug Self-Correcting Number Puzzles set is a delightful gift for kids 4 to 6 years old. Add the Melissa and Doug 200 Wood Block Set to round out the hands-on play experience and to give kids an engaging option for screen-free entertainment.
