One of my students came this week with a concept that I had never thought much about. Her teacher taught her students how to add and subtract using what she called "Arrow Math". As my student described it, I realized it was just a visual way of representing mental math.
My interest was piqued and I had to google it to find out more. I stumbled upon an article by Wendy Petti, called Picturing Mental Math. She describes it perfectly.
I liked how she referred to adding this way as, "mental math with training wheels." I may use this method in my tutoring, but not sure about it. I know I teach this skill, just not this way.
Has anyone tried this way before? Let me know your thoughts.
