For the purpose of describing the activity, we chose beans and foam sheets. You can use any media you would like to fill up your container (i.e. corn kernels, cotton balls, macaroni, bird’s seeds, send, etc.)and any objects to hide (i.e.buttons, pom-poms, pegs, coins, etc.).
Use the foam sheets and cut pairs of different shapes (you can also use different color sheets and cut a pair of the same shape in each color). Fill up the container with the beans. Hide one shape from each pair inside the container and place the other shape in front of the child.
Have the child dig his hands through the beans and find the matching shapes, taking them out one shape at a time.
