Explain to your child that a line plot is a way to organize information. For example, if they need to arrange objects, they should draw a line plot. Now, have them help Tom measure the objects in his pencil case in inches. Then, have them check the line plot that accurately shows the length.
Have you and your kids ever done a family height measurement? How did it go? If they're familiar with it, this worksheet may be simpler. The picture shows a family with their heights recorded. Get your kid to look at the line plots and choose the one that shows the family's heights accurately.
