From: Kristina To: Teacher2Teacher Public Discussion Date: 2004032310:45:30 Subject: Re: help asap Hi, To be honest, I would start by asking the student how he solved the problem. I can guess about what he did, but unless I see more problems with the same mistake you can't be sure about the concepts he's missing. > 15 > __ >6)36 > 6 > __ > 30 > 30 > ___ > > >a) Why does his reasoning not allow for the correct answer? > I'm not sure why he decided to start with a 1 in the quotient. He may have asked himself, "how many times does 6 (divisor) go into 6 (last digit of the dividend)?" >b) What should I do to help this student understand why his approach >is not correct, and how could I help facilitate an understanding that >will allow for this correct answer? For one thing, you might have him use graph paper for division so that he's forces to write his results in the proper column. If he did what I said above, he should have at least written the 1 above the 6 instead of the 3. He might eventually see that his answer is not lining up right. Also, he needs to be taught to start by dividing into the first digit. Instead of asking himself how many times 6 goes into 6, he should ask how many times 6 goes into 30.
