Over the years, Iāve developed some thoughts about what makes a Waldorf math lesson different from a mainstream one.
In my teacher training, I, of course, learned about the importance of building imaginative pictures to help those math concepts stick, but I had mixed feelings when I used that approach in the classroom. Though thinking of the long division symbol as a house, for example, helped a few kids, for most of them, the image got in the way. After all, thereās nothing intrinsic about the long division process that connects it to the image of a house. In that example, using the image felt contrived and artificial. Not helpful.

There were also times when I found studentsā facility with the processes limited by the image. When their first impulse was to think of the image when facing a math problem, they had to go through many steps before being able to solve it. I realized I had to teach them how to let go of the image so their thinking went straight to solving when they encountered a problem.
At the same time, I recognized that the approach that my own teachers used when I learned math wasnāt the best, either. I learned how to solve math problems by learning ātricks,ā without really understanding why the processes I used worked. For example, I didnāt know why I was supposed to put a zero in the ones place when solving a double-digit long multiplication problemāmy teachers just said thatās how you did it. I didnāt understand why the whole long division process workedāI just memorized the steps and implemented them. Lucky for me, I was pretty good at remembering how to do something.
As I was teaching, I realized that my students would be best served by connecting math concepts and processes to information they already knew. That way, they could look at an unfamiliar problem, recognize something about it, and come up with an approach to solving itāeven if I hadnāt taught them the ātrick.ā
This defined my way of thinking about a developmental approach to math, and from this, I identified a few key reminders for myself. (BTW, my approach to math was greatly informed by Elementary and Middle School Mathematics: Teaching Developmentally by John Van de Walle. This book was recommended by my teacher training instructor Nettie Fabrie, who, with her husband Wim Gottenbos and Jamie York, later wrote a great Waldorf math resource called The Teacherās Source Book for Math in Grades 1-5.)
