Puzzles for the Classroom

Free puzzles teachers can use tomorrow: no student accounts, works on Chromebooks and tablets, five levels for mixed abilities.

Why these puzzles

Short puzzles make good starters, early-finisher work and maths-centre activities, and the same puzzle stretches the quickest student on Demon while others are on Beginner.

Tips

  • Give everyone the same puzzle and let each choose their level.
  • Ask the class to share strategies, not just answers.
  • See the For schools page for class codes and reports, coming next.
