KenKen® puzzles are a great way to improve logical thinking skills and, well, make you smarter! This challenging puzzle plays out on a 5x5 grid and will have your fifth grader using addition, subtraction, multiplication, and division. We suggest keeping an eraser nearby...

What You Do:

Using the digits 1-5 in this 5x5 puzzle, fill the small squares with digits so as not to repeat a digit in any row or column, and so that the digits within each heavily outlined area will equal that area’s corner number when combined using the indicated operation.
