A further peer assessment activity I use with GCSE pupils is ‘Switch It! It works perfectly with smaller 4 mark questions which pupils often fail to get full marks on due to a lack of subject knowledge.
The activity is rather simple as you can see from the picture above -pupils sit opposite each other, answer one of the questions and then switch the sheet around to peer assess and add improvements. This is then photocopied so each pupil has a copy.
Attached is ppt. and worksheet example.
