For grown-ups
A calm corner for the classroom
Quiet, focused puzzles for early-finishers, golden time, or a gentle number-sense warm-up. Project it, print it, or send it home.
How teachers use it
Sudoku builds the same skills you're already nurturing — logical reasoning, perseverance, and reading a grid by row, column and box. It works as a whole-class starter on the board, or as an independent activity at the puzzle station.
Three ways to fit it into the day
- Morning starter: project a 4×4 and solve one row together.
- Early finishers: a printable worksheet at the table — no screens needed.
- Take-home: send a picture-sudoku PDF for families to enjoy together.
Printable packs
Every puzzle is available as a clean, ink-friendly PDF — sorted by grid size and age band, ready for the photocopier.

- Why does sudoku work well in the classroom?
