At a particular point you need to get the group to review what they have done so far, this naturally happens when the group start to realise their idea won't work and the activity from the group slows down. Here state "I think we have done well so far, but do you this idea will work? We have about 20 minutes left, shall we carry on with what we are doing or try a different approach?" The response will either be silence or "what else can we do?"All Rights Reserved
