Have a go at these fun butterfly-adorned 4x4 sudoku puzzles with the kids - there are 12 in total in the pack, a pack of answers and a large display version for putting on the board too.
This set of butterfly sudoku is still using a 4x4 grid but children will need to start using their logic skills to work out how the numbers fit into the grid. Great fun!
