Now draw a picture that will help you answer this question correctly. 
IMPORTANT:: Whether to give this skill additional practice is not determined by if the answer is right or wrong, but rather, if a quality picture is drawn that can be used to solve the problem correctly. The picture should have enough detail to help the student come to the correct answer by simply looking at the picture.
