Is your math student ready for a challenge? He will need addition, subtraction, multiplication, and division in order to solve this KenKen® puzzle!

KenKen® is a math logic game that was invented by Tetsuya Miyamoto, a Japanese math teacher. He wanted to make learning more fun, and he accomplished just that! Many of his students would rather be playing KenKen® than watching TV. We hope your child loves this little game just as much! Here's how to play:
