While first reading this article I was slightly overwhelmed with the amount of information. However as the article progressed, I continued to see an increasing amount of methods (both right and wrong) that I recognized from first hand experience. Throughout high school I was continuously asked to tutor children (typically students between first and fourth grade) and so one of the most commonly used methods was the additive method. The children I tutored, especially the younger ones, found it difficult to distinguish when to use the multiplicative method versus the additive method. Originally I found this frustrating but reading this article, and in particular the section on the ‘Mr. Short and Mr. Tall’ experiment, made it clear as to why the kids didn’t understand. 

I am also studying astronomy in which we are studying Newton’s universal law of gravitation and hence this was one of the more interesting and appealing sections of the article for me. That being said, I think the author could have expanded upon this example by describing, for instance, the inverse square law in which tripling the distance between the objects would weaken the force of gravity by 3^2 and explaining so people who haven’t covered the subject would understand.
