Teach it right.

R is one of those student who argues and complains.
His two favorite phrases:
"You didn't show us that."
"Yeah, well, you didn't teach it right."

Definitely a student who makes me want to claim the victories while I can.

Yesterday was a practice day in his class. I gave them time and space to work, checking in with everyone periodically. After looking over one problem he'd solved, I told him it looked great.

"That's all you have to do? That's so easy."

A relief to know that even though the day before I hadn't taught him anything, he can work through problems that require mastery of previous concepts in addition to the new material.
