Playing with Coins and Mathematical Sudokus

The challenges in this feature give your learners the chance to think about possible solutions in different ways.

Along with the Five Coins task, we are introducing a variation of the well-known Sudoku, by including mathematical clues which challenge your learners 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 them to get stuck into!

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

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