Student (10 years old): Ms. Kim, what's 6 x 4? Is it 24 or 28? Me: What do you think it is? Student: I don't know, I'm leaning towards 24. Me: That sounds good to me. Student: Are you sure? Me: Are YOU sure? Student: I'm positive! Me: Then why did you ask me? Student: I kind of just wanted to double check.
