Who hasn't dreamed of building the tallest tower possible? These stacking blocks from Open The Joy are perfect for the occasion. They'll help children develop fine motor skills while learning the vocabulary of emotions. Stacking, building and nesting are all part of the fun. Each side of the block features a different character, and once stacked and lined up, you'll notice the increasing evolution of emotions from bottom to top. This game includes a multitude of activities, such as imitating the characters' faces or having the child repeat each emotion. Once the game is finished, nest the blocks one inside the other and close with the lid for easy storage.
