This webinar will discuss what it means to understand the concept of standard deviation and share a sequence of activities that can be used to help students develop variability. Particular attention will be paid to one activity that challenges students to work together to consider center and variability together, developing a better understanding of the standard deviation. The activities discussed are accompanied by detailed Lesson Plans, developed through our NSF-funded AIMS project.
