MATHLETES BE ADVISED! Want to put your student’s math skills to the test? Sony Global Education and Edmodo have partnered up this month to deliver Global Math Challenge. The competition comes in the form of a set of puzzles and brain teasers created by the Japanese Prime Math Committee. This one-time math test will start and end on September 27 and be available in English, Japanese and Chinese. Taking the math challenge is free, but if you want more than a score, it will cost you $12 to know your global ranking and step-by-step explanations for every question. This isn’t the first challenge hosted by Global Math Challenge; the first was held last November, when over 22,000 people participated.
