Here are some of my videos from pre-student teaching in a flipped classroom. The class ranged in grade level from freshmen to juniors. I was able to teach the flipped lessons to two different hours. During class time instruction I would use the first 10-15 minutes to review the lesson and answer question. The rest of the time was for student to work on the homework or watch the next lesson.
