One round from AP Calculus AB — Unit 4: Contextual Applications of Differentiation

Four students see

Speeding Up vs Slowing Down

Speed increases when velocity and acceleration share SAME sign; decreases when OPPOSITE signs.

The fifth sees

Same-sign-acceleration

That is all they get — a hint, not the term the other four are holding — and they have to describe it first.

The Mole knows two signs have to match. They can talk about velocity and acceleration agreeing and sound right — and never get to what happens when the two disagree, which is the half of it every question is actually about.

Recognizing a word is not knowing it

Calculus is the subject where a student can run the procedure perfectly and not know what the answer means. Saying it out loud is where that comes apart.
