The 24 game for the classroom.
A quick mental maths starter with one target, four numbers and plenty of different routes.
Try it as a class
Put four numbers on the board. Give everyone the same target: 24. Every number must be used exactly once. Ask pupils to show their route, not just the answer.
Useful prompts
Can you find a second solution? Can you solve it without division? Which pair would you combine first, and why? Can someone explain a different route?
Printable practice sheet
These are public practice puzzles for the classroom. Give pupils space to write one route to 24 for each set.
