People love the feel of these smooth wooden shapes. We use that natural interest in a variety of activities that challenge the senses. The Mystery Bag consists of ten pairs of wooden shapes including cubes, rectangular cubes, prisms, spheres and egg shapes in a cloth bag. The experience of looking at a piece, interpreting it and then finding its match is very different than simply seeing the object. This activity provides a connection between the two. It stimulates the sense of touch by eliminating distractions and helps with cognitive function through the matching process. We start exploring the different shapes by placing them on templates and observe that the shapes take different forms depending which face is placed on the template. Once the person is familiar with the shapes we move to activities that involve touch alone. By placing the pieces in the bag and feeling them without seeing the shape, different areas of the brain are stimulated. The instructions detail how to guide the person to explore the pieces.
