Seasider Posted July 17, 2015 Share Posted July 17, 2015 I don't recall learning short division, and I honestly don't remember going through it with my older kids. What do you think? Is it helpful/necessary? Or does it go into the same category as casting out nines? Just trying to determine how much time to devote to it as I lesson plan.

EKS Posted July 17, 2015 Share Posted July 17, 2015 I think that short division is extremely helpful. I never learned it in school, but my mother taught me when I was in 4th grade and it made my live so much easier! I wasn't able to teach either of my kids long division without teaching them short division first. Quote Link to comment Share on other sites More sharing options...

I can't for the life of me remember what my other kids did with this. That's frustrating! Quote Link to comment Share on other sites More sharing options...

kirstenhill Posted July 17, 2015 Share Posted July 17, 2015 I love short division. I wish I would have learned it as a kid. I am too lazy to go search it on youtube right now, but there are some good explanatory videos on youtube that show how to do it. My two older kids prefer it when they can use it.

Mrs. B Posted July 18, 2015 Share Posted July 18, 2015 I just found this. http://www.themathpage.com/ARITH/divide-whole-numbers.htm Teaching 4th grade math isn't as intimidating to me as it was 5 minutes ago before reading how short division works. Thanks! Never heard of this method before happening upon this thread. 2 Quote Link to comment Share on other sites More sharing options...
athomeontheprairie Posted July 18, 2015 Share Posted July 18, 2015 I love short division. But I also teach casting out nines :-) 1 Quote Link to comment Share on other sites More sharing options...
IsabelC Posted July 18, 2015 Share Posted July 18, 2015 I thought everybody learnt short division before long division, until I found that MM makes you do long for everything and had to show the kids myself. I don't see the point of using long division for everything. I always tell the kids that there is usually more than one way to solve a problem, and that part of problem solving is picking the best/easiest tool for the job. Doing long division all the time seems to me like pulling out a food processor to stir sugar in your coffee. 4 Quote Link to comment Share on other sites More sharing options...
Tanikit Posted July 18, 2015 Share Posted July 18, 2015 We were taught short division first at school and then long division for dividing by two digit and greater numbers. My DD7 has been taught long division first and I will have to go back and teach her short division later - short division involves many mental steps which can lead to errors unless both multiplication and subtraction facts are very well known which is perhaps why it is usually taught with dividing by the smallest numbers first.

kiwik Posted July 18, 2015 Share Posted July 18, 2015 I was never taught short division but it does look iseful. I think it would be best taught last though. 1 Quote Link to comment Share on other sites More sharing options...
Halcyon Posted July 18, 2015 Share Posted July 18, 2015 I only know short division LOL. I taught my kids that first and then long division, and they can't understand why anyone would choose the latter. 1 Quote Link to comment Share on other sites More sharing options...
Seasider Posted July 18, 2015 Author Share Posted July 18, 2015 I love short division. But I also teach casting out nines :-) Haha! We have learned casting out nines, but haven't made any attempts to use it outside of the assigned lesson questions about it! Quote Link to comment Share on other sites More sharing options...
Junie Posted July 18, 2015 Share Posted July 18, 2015 Casting out nines... :ack2: Also, I never could figure out how short division was better than long. I'm a visual learner and it helps me to see every.single.step. Quote Link to comment Share on other sites More sharing options...

MrSmith Posted July 19, 2015 Share Posted July 19, 2015 I just found this. http://www.themathpage.com/ARITH/divide-whole-numbers.htm I was really digging this article until it said "Long division now properly belongs to the history of mathematics." And then this gem: "For those students still required to do problems in which the divisor has two or more digits, we include the following example." Now I want my two minutes back.

Tanaqui Posted July 27, 2015 Share Posted July 27, 2015 I was really digging this article until it said "Long division now properly belongs to the history of mathematics." Asimov predicted this, and he's right: Being able to do ones own math really does give a feeling of power. Nine times seven, thought Shuman with deep satisfaction, is sixty-three, and I don't need a computer to tell me so. The computer is in my own head. (Of course, I haven't read the link. If I'm misreading the quoted portion upthread, forgive me.) 1 Quote Link to comment Share on other sites More sharing options...
