Ben and Mike were both dieting. Ben went from 200 to 180 pounds while Mike went from 240 to 219 pounds. Who was the more successful dieter? A student might incorrectly think Mike was more successful, because he lost 21 pounds and Ben only lost 20, because he is thinking additively. The teacher might need to use some of the strategies from Chapter 17 to help develop conceptual understanding of percentages.
