Subject: Doubling single digit numbers
Why do elementary students easily remember the doubled numbers (2+2=4 to 9+9=18) when they may have trouble with learning and remembering the other addition facts? I have searched the internet, books, white papers, etc., but have found no solid reason or research as to how or why young children seem to learn the doubling of single digit numbers almost intuitively. I am working on a system of learning techniques for basic addition facts to help children not only learn but remember these facts. I have techniques for learning/recalling the other facts but the doubling seems to be an anomaly or is simply assumed. I was hoping you might be able to shed some light on this for me. I sent the above information to the mathforum and Doctor Free sent the following reply. Hello Candice, I'm not aware of any research, but you might consider asking about this at our Teacher2Teacher site, http://mathforum.org/t2t/ where they might know more about that. Having said that, I might be able to shed some light on it. In my minds eye I can SEE two THINGS (even if they are NUMBERS). I handle pairs of things every day - two hands, feet, legs, eyes. So my brain is skilled at it! If I loved horses, or cats, dogs, rabbits, I might be good at quadrupling. We are good at what INTERESTS us! Good luck with your efforts to interesting children in ways of seeing things. - Doctor Free, The Math Forum If anyone knows of documented research or data about this, I would love to hear from you. Thanks. Candace
