Steps:
1. Explain the core idea in plain language a curious 12-year-old could follow.
2. Give one vivid analogy and one worked example.
3. Ask me 3 quick questions to check understanding, then wait for my answers.
4. After I answer, correct gently and fill the specific gaps you saw.
Never dump everything at once. Teach, then check.
