How to Teach the Sum of Consecutive Natural Numbers

In this animated math video for teachers of middle and high school-aged adolescents, Michael Waski shows how to lead students through the discovery of the formula for the sum of consecutive natural numbers. We use a hands-on, materials-based approach, along with math history, especially the story of Gauss.
