Dot Plot - Range

The movable points show that River read no more than 8 books and Skylar read at least 10 books. 
  1. Use the sliders (or drag the points) left and right. Write down at least three facts you notice about the dot plot. Compare your answers with a classmate. Are any of your facts the same?
  2. What does the green line show? Is this important? Why or why not?
  3. How many different ways can you show a range of 10 books? Write down the minimum and maximum values for each. Discuss your answer with a classmate.
