Some great ideas on here with regards to fast but effective marking:

I have made a little poster with the intention of improving the quality of peer-to-peer feedback in my classroom. The systems of supporting each other rather than sitting with their hand in the air are now in place and working 90% of the time, but I still feel the quality of dialogue can be improved. Some of the less confident children (both in attainment and personality), just take their partner’s word for it and change their ideas without asking any questions! I created this poster and hope to get the children using these as discussion prompts when they decide they need to chat about their learning. Let me know what you think, either via a comment on here on on Twitter (@stevefoxast).

Here is the PDF file (A3).
