These are videos I created during lock down for my high school math classes. Simple to follow, no frills, casual speaking, guided notes, sometimes cool music at the beginning, and my face is not in the video. Just math. It's just me writing math, graphing math, and explaining math. Always thorough and well explained. Students in my class use the Notability app on their tablets to write these notes, but you can also print out the PDF to write on.
