01 / When the next line won't come
You know the formula. The pencil still stops. Hand the problem over. Xiao Yi writes the derivation where you can see it. Ask about the step you can't pass. When it clicks, solve one yourself.
Mark what you were given.r · given
Write this step's formula first.S = πr²
Take it slowly. If you stop, ask.Result · ask again
AGENT
Xiao Yi sits beside you. It looks at your problem, meets you at the step where you stopped, and writes down why. The end of the whole problem can wait. If you still feel unsure, it stays and practices just that step with you.
YouI know the area formula. I just don't know to write the radius first.
Xiao YiEvery later step grows from here. Mark the radius, and the formula knows what to use. Want to try just this once more?
FEATURES
It is there while you listen, and still there while you try. All of it stays with your own problem.
The problem is opened up. Formulas and the derivation stay on the board, as if someone were writing beside you. When you stop, you ask about that step.
While that step is still warm, try one more problem on the same idea. If it goes wrong, go back to the step you just left. You don't have to guess from the start.
The formula you will forget becomes a card you can turn over. Next time, you don't have to reread the whole set of notes.
The page you actually worked through stays. Next time you open it, it is still this problem.
PATH
The path through one problem is short. Understand this step, then walk it once yourself.
One question on an exam, one page of notes, or the step you cannot get past.
Where the formula comes from stays on the board, line by line. If you stop, you continue from this problem.
Try one practice problem. You can still ask Xiao Yi. The formula stays on a card for next time.
