Printable Sudoku for teachers

Use Sudoku to practice explaining a logical decision. Choose an Easy weekly pack below for seven puzzles and a separate answer page, or change the difficulty for your group.

A short classroom routine

1. Give learners the rules sheet and explain rows, columns and boxes.
2. Work through a single-candidate example together.
3. Ask learners to explain why a digit is forced before writing it.
4. Compare reasoning in pairs, then check answers after the attempt.

Choose a worksheet layout

The weekly pack below has five pages: four puzzle-and-tip pages followed by one solution page. Print pages 1–4 for learners and keep page 5 for checking. The four-per-page and six-per-page packs use fewer sheets and omit answers.

Three classroom session outlines

Introduce the rules together

Show a partial grid and ask learners to name the missing digits in one row, column or box. Demonstrate how the crossing groups rule out a candidate, then let pairs explain one placement before continuing independently. End by asking each pair to describe the reason for a move.

Practise candidate notes

Choose an unsolved area with several possible digits. Model small notes separately from confirmed entries, then ask learners to update them after a placement. Compare the before-and-after notes and discuss why each removal is allowed. Use the existing beginner course for guided practice.

Review a challenging attempt

Let learners choose a comfortable puzzle or a harder one. Ask them to mark a point where they paused, explain what they checked and identify a next step. A clear explanation or a corrected mistake can be the session's outcome even when the puzzle is unfinished.

Use the same pack in different ways

Keep a few sheets available for early finishers, solve one grid collaboratively, or ask learners to write a short explanation of one move. Choose difficulty from their experience with Sudoku rather than their age alone. Preview the chosen puzzle before the session and keep its matching answer page aside.

Support different learners

Use the single-puzzle layout when more writing space helps. The interactive beginner course can support a demonstration; the strategy reference gives experienced learners a next step.

For a smaller teaching example, see the checked 4-by-4 grid in our Mini Sudoku guide. It is an explanation, not a downloadable mini worksheet.
