Do you know what Chisanbop is? It’s a Korean method of learning to do math computation on your fingers that was used in North American schools in the 1970s and 80s. I took a course in the method and used it with my students for quite a number of years. Chisanbop attracted some media attention. My Elmdale School students and I were featured in an article about Chisanbop in our local Steinbach newspaper The Carillon. This photo accompanied the article.
The system assigns a one, five or tens value to different fingers and children learn to do all the mathematical operations by manipulating their fingers quickly. The Chisanbop method was somewhat controversial because critics said it would prevent children from memorizing mathematical facts but as I searched for current articles about why counting on their fingers is bad for children learning math I couldn’t find a single one. Most educational researchers like Stanford professor Jo Baylor think learning to count on their fingers is actually critical to helping kids understand math.
I know after a time I stopped using Chisanbop in my classroom. I am not sure why. I would be interested in hearing from other teachers who may have used the method or students who remember being taught Chisanbop.
