Ask your student to teach you some math that he feels he has mastered, or is particularly proud of. Or ask your student to show you some class work from last week. This will give her an opportunity to feel proud of her work, and it will give you an opportunity to assist in your student’s learning. By giving your student the opportunity to explain their thinking, you are encouraging them to be more confident, use new vocabulary, and identify any confusion they may have. Also, by explaining their thinking to someone else, they are making that knowledge clearer for themselves.
