"Number Puzzles: Sudoku, Strimko, and Suguru Puzzles" worksheets contain different number puzzles that are designed based on grade-level appropriate challenges. They include Sudoku, Strimko, and Suguru puzzles.

Sudoku puzzles include the numbers 1 to 4, 1 to 6, and 1 to 9, depending on the grade level. Each puzzle includes in-depth directions. Some puzzles also include Sudoku sums, where the two numbers inside the dashed lines equal a certain number, helping students double-check their work.

Strimko puzzles are like Sudoku puzzles, but numbers are located in bubbles and connected with lines instead of boxes. All the bubbles connected by a line must include different numbers, whether they are organized in columns, rows, or random groups. Small puzzles include the numbers 1 through 3. More complex puzzles might include numbers up to 4, 5, or 6.

Suguru puzzles feature a grid of numbers that are split into irregular-shaped regions. The same number cannot be next to each other in any direction, and one of each number must be located in each region. These worksheet pages have more detailed instructions, and each puzzle shows the missing numbers so students can cross them off as they fill them in.

Number puzzles can help support math concepts, in addition to promoting problem-solving and critical thinking skills. They are a great way to challenge high-level students who finish a math lesson early, but they can also be a great partner activity, an early finisher activity, or even for extra credit.

Sudoku puzzles are a great option, but so are other number puzzles. Strimko puzzles feature numbers in bubbles that are connected by lines, while Suguru puzzles feature grids of numbers that are divided into irregular-shaped regions. Number patterns are also a good choice, while riddles can incorporate story problem skills. If you want to incorporate operations, try a math word search or crossword puzzle.
