This is a new jigsaw puzzle based on shapes that repeatedly connect to fill the entire surface. Each puzzle consists of 101 identical crescent shapes. Any two can connect in 69 different ways as you rotate them, and flip them back to back. Simply fitting them together is not enough to get a proper match. You have to develop your visual matching skills. Pieces are large and there are a lot of images to work with. These patterns help to develop an appreciation for the natural and architectural world. It helps children to make connections between observations and technology. Finished dimensions are 17x26.
