Materials: Container(s) and objects with different textures, like seed pods (“spiky balls”), feathers, pencils, rocks. Cloth/towel to lightly place over containers. Alternatively, socks work well in lieu of containers and cloth/towel.
Activity: Show the objects to the child, then hide them, placing each in a container. Without looking, have the child place his/her hand(s) in a container, and ask him/her to identify the objects.
