Another worksheet with a ‘wheel’ of questions to practise subtraction of whole tens. year 5’s should find this quite easy and it is worth considering what approach they take to finding all the possible questions.
Start with a high number and go through the spokes to make a sum eg 130 – 80.
By year 5 children will certainly have come across negative numbers so there is no reason why they could not work out a question such as 130 – 160 as -30. Others will say that this negative sum ‘can not be done’ which is a correct way of looking at it if they are using the traditional pencil and paper style of thinking for subtraction.
