We've all been there.  You're sitting around the dinner table and you ask your child,
​"What did you learn in school today?"  And in response, you get something like this:

Before the end of school every day, I will ask the students what they learned that they will be able to tell their momma when they are asked the unavoidable question that evening.  If they don't answer with something more than a lost look, keep asking.  Eventually you might get an answer.
