    The importance of understanding number lines has really been driven home to me this year in Math 8 as we used them as a tool to help understand operations with integers. Now we are using coordinate planes to transform shapes and the students who aren’t comfortable with number lines are struggling since their is now a vertical and a horizontal number line. I am realizing after watching this video and reflecting that I need to go back in my intervention class and have them work with one number line until they have a better understanding.

    Also, what a great example of when the algorithm is less efficient than number sense!
