Does your fifth grader love puzzles? This one is a great introduction to KenKen®, a logic and math game from Japan. Players need to use different operations (addition, division...) to decide where each number goes within a grid. KenKen® was invented by a math teacher, so we know this activity has a lot of educational value! Here's how to play:

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.
