Mr. Robb's Math is a YouTube channel containing 555 videos produced by high school mathematics teacher Bradley Robb. Mr. Robb's videos explain and demonstrate solving problems in Algebra I, Algebra II, and Calculus. Most of the videos are recorded while Mr. Robb is teaching. You can find the videos on the Mr. Robb's Math YouTube channel or visit Mr. Robb's website WowMath to find the videos organized in sequence with accompanying screenshots.
This is a lab activity that I can use in my course to introduce students to linear functions. At this time, I am contemplating whether to use it as an in-class activity or having it that the place of a video for a lecture and become a lesson that is discovery for students to use on their own.
This is the concern for using it as an online lesson. This requires the use of Java and it could be an app that students do not have on their computer at home as I had complications with it at first.

same
thing with your graphing calculator if you have one, or with any other
computer algebra system that you might have available on your
computer.)
