Per request, I created a short video showing how I create customized number lines on WORD. This post also includes a link to a WORD document with 3 customized number lines: time, money with negatives, and miles.
In the video I show how I created the time number line. In the top image below, you can see the table highlighted. I then show how I copy and paste the number line and then edit to create units with money, with negatives.
Here is a screenshot of the video. You can see the number line in an early stage of development. Below the image is a link the video.
Below is an image of the three customized number lines. Here is a link to the handout, which is in WORD format to allow you to revise to suit your work with students.
