Are you a math whiz?

Are you a math whiz? Care to test some recent research ideas? Here is an article from the New York Times that your 'number sense' to approximate quantities of objects can predict your success in math class. "One research team has found that how readily people rally their approximate number sense is linked over time to success in even the most advanced and abstruse mathematics courses." What do you think? Try the test at home. This is definitely going to be something to play with in class next week.Read the article and take the test: "Gut Instinct's Surprising Role In Math".
