• Lightbulb Students should use their prior knowledge and exposure to number lines to be able to represent equally spaced whole numbers on a number line and determine the distance by the number of whole units between the starting point and ending point. Students should understand that a number line is represents the distance from zero and the scale of the number line can vary depending on the distance between the tick marks.


  • Use the number line shown to answer the following questions.
     Number line

    b)  What is the distance between Points A and B?

    c)  What is 40 less than Point C?
