"Strimko Puzzles: Connecting Numbers in Lines and Groups" features puzzles that are similar to Sudoku, but with more flexibility. Instead of writing each number in a series within each box, column, and row, this worksheet features numbers in a grid of bubbles that are connected with a line. Each group of lines, no matter their configuration, must include one of each number.

Each worksheet displays the rules at the top of the page, using images to illustrate how each column, row, and connected group must contain different numbers. Then, four different puzzles are grouped in boxes on each page, telling students which numbers to use. Simple puzzles use the numbers 1 through 3, while other puzzles may go up to 4, 5, or 6.

Puzzles and brain teasers can be a great way for students to practice their critical thinking and problem-solving skills. They can be a fun way to keep students engaged during downtime when they are used as an early finisher activity, or they can be a fun way for students to decompress and work together in pairs.

Sudoku-style puzzles can be fun for students. They include traditional Sudoku with nine numbers in each box, but you can also find smaller Sudoku puzzles for young students.

Some puzzles follow the same principle but put a new spin on it. For example, you can find Strimko puzzles that feature grids of bubbles that need to be filled in with numbers. Groups of numbers are connected with lines, and no matter what their configuration, they must include one of each number. The nice thing about this style of puzzle is that they can be very small, only including the numbers 1 through 3, or they can be very large, including the numbers 1-4, 5, 6, or even more.
