My son has no clue how to do long or short division or use an equivalent method to work out 484/8
When I showed him he understood and picked up reasonally quickly. I am sure that most children in my class could do long division by the age of eleven.
I feel that children should not reach for the calculator until they learn trig. I think that children's over reliance on calculators is why British children are weak at maths. Also the tenancy to try and teach 15 million different methods of doing division without mastering one!
