Increase the complexity of the questions and have the child draw what she sees. For example: “Visualize a circle in your mind, now cut it in half. Cut the half in half again. Draw what you see.” Or, “Picture a rectangle in your mind. Draw what you see. Now, in your mind turn, or rotate, the rectangle. Draw what your rectangle looks like now.”
Ask the child to close his eyes and think of a square. Once he opens his eyes, ask him to find a square in the room. Continue this process with a rectangle and a circle.
