Teach the lesson
- 0–5 minutes
Start and recall
You do or ask: Ask pupils to recall the prerequisite: Pupils know knight moves, check and piece values. Have everyone choose an answer before you discuss it.
Pupils do: Pupils explain a known rule and compare their answer with a partner.
- 5–12 minutes
Demonstrate the idea
You do or ask: Set White Kf3, Nc1; Black Kd2, Rc5. White to move. Show 1. Nb3+, which attacks both king and rook. After 1...Kd3, demonstrate 2. Nxc5. Ask why Black had to answer check first.
Pupils do: Pupils predict a move or result, then explain which rule confirms it.
- 12–22 minutes
Guided pair practice
You do or ask: One pupil finds the fork square; the other tries a legal king reply. Swap and finish the combination, checking that the second target is still available.
Pupils do: Each pupil thinks independently first. One explains and the other checks; then they swap roles.
- 22–32 minutes
Independent worksheet
You do or ask: Hand out the pupil worksheet. Some pupils stop after the checking move. Ask what the combination has actually won so far. Others choose a knight fork square that is immediately capturable: test that defence.
Pupils do: Pupils record an answer and a reason. They use the board to test their ideas without viewing the answer sheet.
- 32–40 minutes
Discuss and check
You do or ask: Ask what makes a checking fork more forcing than a fork without check. Discuss one common mistake and return to the stated learning goals.
Pupils do: Each pupil gives an individual exit answer. A pupil who needs support repeats a simpler example before moving on.
Support and extension
Mark the knight’s eight possible destinations with counters. For an extension, let pupils add a legal defender and explain whether the original combination still works.
