How a lesson works

Four steps. One clear path.

Step 01

Watch

A short, focused video explains the concept clearly — pause and rewind at your pace.

Step 02

Know

The big idea in plain language — an analogy, key terms and a diagram, not a wall of text.

Step 03

Practise

Match, quiz, flip-cards and fill-the-gaps — the retrieval practice that makes it stick.

Step 04

Prove it

A printable worksheet with model answers and marking criteria — check yourself or hand it in.
