I printed out the first 3 slidesin A3 and stuck them around the corridor outside my classroom. Working in pairs, one of them had to stay in the class with the answer sheet whilst the other person went to find the answers on the texts outside.
Time penalty for anybody caught running/shouting answers across the classroom.
I gave them 5 minutes at the start to organise themselves and how they were going to collect the information. (PLTS) (Independent Thinkers)
They were encouraged to swap over half way through.
