***KENKEN® AT THE MATH FORUM
The Math Forum is excited to partner with Nextoy® to 
offer a collection of KenKen puzzles. KenKen is a number
puzzle related to Sudoku, but even more mathematical. We 
have puzzles ranging in size from 3x3 to 9x9, at four 
difficulty levels, with many combinations of 
arithmetic operations.

KenKen puzzles offer great opportunities:
  - to practice arithmetic skills in new and 
      interesting ways
  - to learn and get better at problem-solving strategies
  - to work on organizing and communicating
      mathematical ideas

Math Forum PoW members enjoy complimentary access to 
KenKen puzzles, each of which comes with a printer-
friendly view, an interface for submitting your work, and 
a solution viewable by teachers. Teachers with class 
accounts may further view the work their students submit 
when solving KenKen puzzles.

We allow uploads in answer submissions, which makes it 
much easier to show KenKen work (or even steps, moments 
of reflection, etc.). And we offer a table-making tool 
in the explanation box, for an alternate method of 
displaying similar information.
