Introducing Mathematical Sudokus

We are introducing a variation of the well-known Sudoku, by including mathematical constraints which challenge students to apply their knowledge of the four operations. For each grid size, there are four different puzzles, at each of three levels of difficulty, so plenty for your students to get stuck into!

To introduce the Mathdokus, and to give a flavour of the kind of strategies that may be useful, you may like to watch this video.

The last date for submitting solutions to the live problems is Monday 31 October.

You can watch a recording of the webinar in which we discussed the mathematical thinking that can be prompted by these activities.

The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to embed rich mathematical tasks into everyday classroom practice.

NRICH is part of the family of activities in the Millennium Mathematics Project.
