The original question asked how the student go this answer: > 15 > __ >6)36 > 6 > __ > 30 > 30 > ___ > > >a) Why does his reasoning not allow for the correct answer? It is often easy to overlook the truth in what is happening - let's analysewhat the student actually did - and why. The first question addressed by the student was 'how many times does 6 go into 36'. His original answer was 1. > _1 >6)36 > 6 1 x 6 is 6 ____ > 30 subtracting gives 30 the next question asked was 'how many times does 6 go into 30' > 30 > ___ his (correct)answer was 5 which should have been written like this: > 5 > _1 5 + 1 = 6 - the answer. The student demonstrated knowledge of >6)36 the division process - but had an answer formatting issue > 6 > __ > 30 > 30 > a more standardized was of teaching division like his would be as follows: __ 6)36| -6| x1 --| 30| -30| x5 --| The answer then would be 6 is subtracted 6 times from 36
