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.
