MatchStacks are fun and educational, so the kids in your life will love putting their brains to work! Each set comes with 16 wooden discs with eight sweet designs, each with a twin. To start, flip them all upside down and mix them up. Now all you have to do is start matching! Encourage kids and guide them through play to strengthen their memory, vocabulary, spatial skills, verbal abilities, and simple logic. There are currently five versions, all of which are interchangeable, allowing you to combine multiple sets for added difficulty. Simple, safe, and sustainable: Those are the principles upon which Treehopper has built dozens of classic toys to work with a child’s imagination. Using natural materials like wood and beeswax, their spirited collection is sure to provide hours of entertainment for creative kids.
