Louise used this figure to model the expression 20 divided by 4. A number line going from 0 to 20. An arrow goes from 4 to 8, from 8 to 12, from 12 to 16, and from 16 to 20. What error did Louise make in her model? The small arrows are pointed in the wrong direction. The small arrows should all end in the same place as the large one. The arrows should start at zero. There should be one large arrow and 20 small arrows.
