Teach it back.
This is the real teach-back mode: a Junior Secondary 2 student holding one honest misconception about ratio. Explain it to her — she restates, asks why, and won’t nod along until your explanation actually holds.
AI student: I’m Amara, JSS 2. I think 3 : 2 means I get 3 out of every 5 — that’s right, isn’t it? Teach me and we’ll find out together.
Good afternoon! Before you teach me — I think 3 : 2 means I get 3 out of every 5. That’s right, yes?
