Learn a method from a worked example

Solves one problem slowly with every step explained, then gives you a similar problem to solve on your own.

Prompt, 2 blanks to fill
Teach me how to {{METHOD}} using a worked example.

Problem: {{EXAMPLE_PROBLEM}}

1. Solve it step by step. For each step, say what you do and why.
2. Point out the step where people most often go wrong.
3. Summarise the method as 3 to 5 general steps I can reuse.
4. Give me a similar problem to solve myself. Do not show the answer until I reply.

Example output

Step 1: write down what we know: 20% off, final price £36. Step 2: £36 is 80% of the original. Step 3: £36 / 0.8 = £45. Your turn: a jacket costs £52 after 35% off. What was the original price?

Why it works

Worked examples are one of the best-studied ways to learn a new method. Asking the model to reason step by step, and then checking your steps the same way, catches the exact point where your method goes wrong.
