There will be 16 math challenges throughout 2011-2012 school year. Students who complete at least 12 out of the 16 math challenges will be honored at the award assembly in June 2012. If you are not familiar with the program, go to www.mathinaction.org to learn more.
Math challenge 9 is all about KenKen−a type of math and logic puzzle invented by a Japanese Math teacher, Tetsuya Miyamoto. KenKen comes from the Japanese word for cleverness. Try this fun challenge and turn in your answers by February 9 (no later than 3 p.m.).Everyone who submits the required solutions will receive a Valentine duck. Good luck!
