The long division method in the the third column is my favourite and the one I recommend we should all be teaching at KS2 by following the steps below! “Your favourite and best long division method looks too hard for my Key Stage 2 children!” I hear you shout! The chunking method for long division with two-digit numbers is set out in the first two columns below it encourages children to think about the relationship between multiplication and division by estimating first how many times the divisor (the number outside the ‘bus stop’) is likely to go into the dividend (the number inside the bus stop). (Note that it also says, “For division, some pupils may include a subtraction symbol when subtracting multiples of the divisor”.) Long division chunking method The Mathematics Appendix 1: Examples of formal written methods for addition, subtraction, multiplication and division “sets out some examples of formal written methods for all four operations to illustrate the range of methods that could be taught”, as shown below for long division. “Divide numbers up to 4 digits by a two-digit whole number using the formal written method of long division, and interpret remainders as whole number remainders, fractions, or by rounding, as appropriate for the context”.
#How do you learn division how to#
It is therefore crucial that children are fluent in division and confident with the accuracy of their answers, and this means finding the right KS2 long division method for your class.ĭownload Free Now! How to do long division according to the national curriculumĪccording to the National Curriculum, when teaching division to Year 6 children should know how to: In all four SATs arithmetic papers that have been released so far under the new curriculum, there have been 2 ‘long division’ (dividing by a 2-digit number) questions. We all know that the arithmetic paper is the one in which we expect the children to score the highest marks, and often, those crucial marks are lost because of inaccuracies in the children’s answers. Long division plays an important role in SATs If you want to know how to teach this long division method at KS2 read on. This process is repeated till you have reached a solution. First you divide, then you multiply, then you subtract, and then you bring the next digit down. Unlike chunking the long division method is set out in a similar way to short division or bus stop method of division but uses a memorable process to get to the answer. The formal long division method is a step by step method of supporting children to understand both conceptually and practically how to divide one three-digit-number by a two or three-digit number. If you feel you need a brush up on all the precursor stages to long division then this article for parents on division for kids is a great start. The quotient is the amount each divisor receives ie the answer in most cases.The divisor is the number you are dividing by.The dividend is the number you are dividing (the number inside the ‘bus stop’.The best long division method builds on children’s on understanding of the bus stop method of short division as preparation for dividing by large numbers.Īs well as recognising the division symbol, before they tackle long division at KS2 children should understand terms like the dividend and the divisor. In Year 5 and Year 6 at primary school, long division usually means dividing a number that is at least three digits by one that is two digits or more, often leaving a remainder, and sometimes with the need to provide an answer to decimal places or as a fraction. Long division is a method for dividing one large multi digit number into another large multi digit number.
When children watch you do it, they think it looks complicated, difficult and unnecessary, and it almost instantly turns them off – until they realise how systematic and logical it is. Long division is probably one of my favourite things to teach Year 6 in maths (I know, I know – but bear with me). Long division: long and divisive, right? Wrong!
Long division plays an important role in SATs.
