In this 3 minute video, Dedra Wright demonstrates how to teach students about the mean as a balance point. She models this concept using a number line and blocks which are manipulated throughout the activity. In the video, two data sets are shown as models and then connected to the written algorithm. A companion video, Introduction to the Concept of the Mean: Mean as Fair Share, is cataloged separately as a related resource.
