This is a collection of resources related to the mean as a measure of center, and the Mean Absolute Deviation as a measure of variability. My MTH 323 class (Probability and Statistics for Middle School Educators) joined with a middle school teacher to teach a couple lessons on these topics. While most of the class got to teach a few students with a partner, my group was able to go in early and observe their teacher – and student teacher – give the lesson. We contributed our ideas in the planning phase of the lesson, and watched to see how it went with the students.
Here are some of the lessons we used, as well as additional resources on these concepts!
