I am a former middle school math teacher in Florida. The videos on this channel were used in my classroom, and out of the classroom as either teaching aids, or extra help. I also taught adult education classes, and have worked at the elementary and high school levels. Most of these videos are taken in one shot with no editing. I didn’t generally have a lot of time to go back and re-record, so I may sometimes have an error in the video. If you find errors, please comment on them. After teaching for 14 years, I needed a change. I am now a computer programmer again. I still love to teach, and hope to continue monitoring and possibly growing this channel.
