What is Sudoku? Puzzles are so much fun! You use your mind and fix pieces together, which in the end, make such a beautiful picture! Just like that, there are mathematical puzzles as well. These puzzles seem difficult, but as a matter of fact, they use logic and concentration. The game is known as "Sudoku." Sudoku is a puzzle game that is designed for single players. Just like crossword puzzles, the puzzle has grids of little boxes, which are known as cells. These cells are stacked nine high and nine wide, which makes a total of 81 cells. These crosswords, instead of letters, consist of numbers. Just like we play hangman and it already has some letters filled, Sudoku has a few numbers already filled. The goal is to fill the numbers from one to nine, such that the number is not repeated in any column and row. However, repetition is an exception diagonally. Sudoku is really fun to play! Just like mathematics, it just needs a little concentration for the prediction of numbers in the cells. Just be careful, patient, and focused, and you can easily solve any Sudoku puzzle! These worksheets will introduce students to the math concepts that are exhibited by sudoku.
