Division using the 'short' method
This week we are publishing a set of pages which look specifically at dividing 3-digit numbers by single digits, concentrating on the 5, 6, 7 and 8 times tables to do this. This is to practise the 'short' division method.
When I was young I was taught the short method before the long method and by repeated practice learned the method, although probably not knowing why it works. Today the long method is usually introduced first as a means of showing exactly how it works, usually with easier numbers. The key to both methods is, of course, a good knowledge of tables, although on these pages the table has been written out to help.
For example: 7)627
'How many sevens in 62?'
'7 times 8 is 56, 7 times 9 is 63.'
'7 goes into 62, 8 times with 6 left over.'
Write the 8 in the answer above the 2.
Write the remainder 6 beside the 7 units, making 67.
'How many sevens in 67?'
'9 times 6 is 63.'
'7 goes into 67, 9 times with 4 left over.'
Write the 9 in the answer in the units and write rem 4 next to it.
It should be pointed out that children need a very good knowledge of tables in order to be successful with this method of division.
These pages can be found in the Year 5 Division and Fractions category.
