Multiples Sudoku Journey
If your students do not know the rules of Sudoku then set aside a little time for them to become familiar with the 'standard' Sudoku.
Work together with the class filling in a few cells to make sure everyone understands the rules - the 3rd, 5th and 7th rows offer opportunities for filling cells easily at the early stages.
Then hand out the sheets and invite students to work in pairs, emphasising that they must convince each other that their suggestions are correct, before anything gets added onto their papers.
Some clues have lots of possibilities and some have few. Which are which?
Which are the most helpful clues to begin?
Provide students with this possible journey through Multiples Sudoku and suggest they try to retrace the route.
