This is like the things you develop yourself as a child although broken down and over simplified. Maybe this should just be for the less intelligent children who do not have the skills to learn their own more efficient method. I can see this wasting too much of an able pupils time. Do you have streaming in America where you filter off children by ability like in Europe?, If so then maybe this is good for the lower streams to gain them insight into what more able pupils do anyway. (Though maybe not so convoluted).
