Math Pickle www.MathPickle.com

Math Pickle is a great website I learned about through NCTIES.  It has creative and challenging math puzzles for all ages.  A great feature is the ability to differentiate the puzzles without students having any idea.  I worked several puzzles and found them engaging, fun, and addictive.  Students will love the challenge and learn at the same time.  The website also has K-12 support videos.  They have been recognized in the NY Times.  There are student created puzzles and you can choose puzzles by grade level and topic.  Many puzzles are featured in TeachersPayTeachers.  This would be a great activity to use collaboratively in partners or small group. #mathpickle
