Choose a simple object for your child to draw. With your finger on the object, slowly trace the outer edges of the object while the child watches. Describe the object as you trace it with your finger. Then let the child trace the edges of the object with her own finger.
Look at the object as you both draw the object with your finger in the air on an imaginary piece of paper. Again, describe the object as you draw it in the air.
Ask your child age-appropriate questions as you engage in these exercises to help her to closely observe the object being studied. Questions could include, "Which of these two sides is longer?" or "Is this edge straight or curved?" Help the child to focus on all of the details of the object.
Instruct your child to draw the lines of the model object on paper with a drawing tool of her choice. Encourage her to keep her eyes on the object that she is drawing and not to look at her paper while she draws. The lines created in this part of the exercise may be rather disjointed when finished, but that is all right.
Give your child a clean piece of paper to draw the object as realistically as possible. Remind her to continue to look at the object often while drawing. Praise your child's efforts, and affirm any improvements that you see.
