A seventh grader walked into my classroom today.
Ms. B: Hi Evan. What's up?
Evan: I'm looking for my math teacher. Have you seen her?
Ms. B: I don't think she's here yet. Can I help you with something?
Evan: Hmm... well, I'm in Pre-Algebra. Do you know how to do that?
[Thoughts of Ms. B: Should I explain to this student that I have taken many many classes beyond pre-algebra? Should I try to explain Differential Equations or Non-Euclidean Geometry?]
Ms. B: Hmmm, Evan. It depends. Let's see.
