Mean absolute deviation can sound very intimidating. I remember being in a master’s class and we had to find the standard deviation of some data. Most people in the class had no clue what to do. Most 7th grade math teachers have been teaching math since before the Common Core came on the scene, so this makes mean absolute deviation a new topic for many of us. If you’re like me, you get worried when there’s a new topic. You want to teach it right, but you’re not confident with how to teach it. At least, not yet. It’s taken me a bit of time to feel comfortable with it, but this year I had so much fun teaching this concept. Let me show you step by step how I broke down and taught my 7th grade students about mean absolute deviation.
I love probability. I can’t really explain why, but I find it so easy to understand and applicable to real life. My students, on the other hand, don’t seem to really know much about it when we start our probability unit and some of them have never even heard of it. I used to get so surprised when kids didn’t know anything about a topic. Now, I just realize that there is a lot to learn about in the world, and I love the chance to be the one to share something for the first time with them. The probability unit is not only fun, it also uses some concepts that we have focused on this year like proportions and rates.
