7th Grade Math Teacher Chris McCloud from the School of the Future in New York, explains how he talks to students about lost class time and how a few minutes each day adds up to a lot of time over a week or a month. He quantifies wasted time doodling or not being focused for 5 minutes in 1 class period to losing 100 minutes in a month; about the equivalent of two full class periods.
