Episode 86 - Why subtraction is so hard

Welcome fellow Recovering Traditionalists to Episode 86.  Today we are looking at Why Subtraction Is So Hard. The topic of subtraction has come up a lot recently in my life and while I was digging into some research I came across an article by Constance Kamii, Barbara A. Lewis, and Lynn D. Kirkland titled Fluency in subtraction compared with addition.  As I was reading through it, I found a section that was thought provoking and I wanted to share with you. All links mentioned in the episode can be found at buildmathminds.com/86 

Om Podcasten

The Build Math Minds podcast is for my fellow Recovering Traditionalists out there. If you don’t know whether or not you are a Recovering Traditionalist, here’s how I define us. We are math educators who used to teach math the traditional way. Flip lesson by lesson in the textbook, directly teaching step-by-step how to solve math problems. But now, we are working to change that to a style of teaching math that is fun and meets our students where they are at, not just teaching what comes next in the textbook. We want to encourage our students to be thinkers, problem solvers, and lovers of mathematics..we are wanting to build our students math minds and not just create calculators. If that is you, then this podcast is for you.
