My year sevens and year eights took tests today. Here were some of their responses:

'All angles in a quadrilateral must add up to 360 degrees so you find out what angles B and D are then you find out A and bingo you've got it'

'Saturday because most people brought ice screams because they cool you down also most people brought cola drinks and they also cool you down'

Question: Katherine uses a calculator to work out 19.8 x 4.1. Her display shows 811.8. Without working out the answer decide whether Katherine is correct.

Pupil 1: 'No because if you times 19 and 4 together you get 76 and then you times 8 and 1 together and you get 0.8 and you add them together and you get 76.8 well thats what I got anyway'

Pupil 2: 'Yes because if you look at the answer it is a sensible answer because if it wasent it would be like 645.347'

Pupil 3: 'Dont no and its far too hard'

Pupil 4: 'I think its right because if she uses a calculator it makes sense'
