A sudoku puzzle is formed from the answers to primarily linear function questions involving x and y intercepts, slopes, parallel and perpendicular slopes. Function notation is used (but the .doc file is editable and so easily changed). Function notation questions are also present, as are a couple of fraction expressions to solve. There are 31 questions which place 31 values into the Sudoku puzzle. Students then must solve the puzzle. It is a "medium" difficulty puzzle, meaning the answer requires some strategy and problem solving, but is certainly possible without using any sort of guess and check or trial and error.
This can be used as an assignment/assessment where the 31 questions are marked and the sudoku puzzle can be part of the assignment or a bonus portion. It can alternatively be a review of material, a handout or simply a worksheet.
See other items in Math Matters MM for other algebra activities and applications for math.
Final numerical answers are provided for the 31 questions and the final Sudoku puzzle solution is also provided, all in a word document.
