This website is one of my favorites to get instruction from someone else on a concept. Khan Academy has multiple people who record themselves working through particular problems, and include step by step instructions. You can search the concept, watch the videos, practice the skill, and even test out on the skill!
Parents, in order to help you better understand what is going on in your child’s classroom, I have added a page titled “Projected Weekly Plans”. This page has been put in place to inform you what your student will be working on during their mathematics and science periods with me. Please check it out! If you have any questions, please feel free to e-mail or call me.
