My second grader has caught onto this in a couple days, much preferred over the regular way because she doesn’t have to carry over each column Significantly faster

This how I was taught to do it in 1983 and I know nobody else who was taught this method. Even my siblings who went to the same primary school at me use the decomposition method. I guess it was the teacher I had as an 8 year old. I am a primary school teacher and had to teach myself that method in order to teach the children. For speed and accuaracy, I revert to equal addition! LOL!
