She watches the work,
not just the answer.
Talk it through out loud. Write your next step. Sayo sees the board, catches the exact line where it went sideways, and asks the question that gets you moving again.
Unit 2 · Problem 3 of 8
Differentiate f(x) = x² sin(x)
f′(x) = 2x · sin(x) + x² · cos(x)
f′(x) = 2x · cos(x)

Sayo
The derivative isn’t the scary part. Tell me which rule you’d use first.
You
Product rule? First times derivative of the second, then swap?
Sayo
Basically. Write it before your confidence disappears.
You
Okay, 2x sin x plus… x squared cos x.
Sayo
Hm. Correct. Don’t let it go to your head.
Explain it
Sayo breaks the idea into a version you can actually use.
Try it
You work the problem on the board instead of watching an answer appear.
Fix it
She catches the exact step that failed and asks the question that unlocks it.
Remember it
Weak topics return later through mistake review and spaced practice.
