Christmas MathDoku

Christmas math resourcesThis resource only just missed our Christmas Activities eBook.

It is a MathDoku, or KenKen type puzzle. We've simplified the more traditional version so that it only includes addition.

MathDoku math puzzle

The idea is for the children to work together to complete each 5x5 grid - they only have a small number of clues and a few simple rules to follow.

The rules are that:

  • the numbers entered into each 'cell' (a number of squares marked out by darker lines) should total the clue number in the top left-hand corner of the cell;
  • only the numbers 1, 2, 3, 4 and 5 should be used;
  • as with Sudoku, no number can appear on any row or column more than once.

 Christmas Math activityThe pdf file attachment below includes four KenKen puzzles (together with answers).

Hi, great puzzle to practise

Hi, great puzzle to practise addition in a fun way. I have adapted the grid to make it an all year round activity. I think I will print number cards with 1 - 5 on, then cut the top left corner off so the target number is still visible. This way the children can manipulate the numbers without having to rub out any errors.
