If you are having trouble with the math concepts or homework, the links below are to a teacher who has recorded videos for each lesson. He will review the concepts and go through the problems. If you are struggling or if you missed math due to an absence, you can watch these to help you. I have not watched every lesson, but the ones I have looked at seem to be comprehensive and helpful if you need a little review or support with a lesson. They are also great if you are absent.
