Welcome to my channel! I’m a math teacher in Appleton, Wisconsin, and these videos are recordings of lessons from my classroom. They’re mainly made so students who were absent can catch up on what we covered in class. Because these are real classroom lessons, they’re not perfectly scripted—mistakes will be made, problems will be worked through in real time, and sometimes we’ll even laugh along the way. The goal is to show the thinking process behind solving math problems, not just the final answer. If you’re here to review a lesson, catch up after being gone, or just see how we approach math in class, you’re in the right place.
