Everyone is involved. Contributions are shared. It’s quick and fun. And it can give you information too (if you collect all of them afterwards.). To do it, have everyone prepared with a half-sheet of loose paper. Ask them to print (legibly) their response to your posed question on the sheet (and tell them it will be shared with others). Now, ask them to crumple it into a loose ‘snowball’, gently toss it into the group, then pick one up and read it. You could ask for 1-2 examples to be read out loud, or you could collect them all, type up and share with the class.
TAG cloud.. sounds nice, doesn’t it?
