Thanks Stemarty, good point. Perhaps, buzzing to answer a question so any team can participate. That seems kind of unfair if a team is answering many questions but bomb games aren't really fair either. That way everybody stays involved. Each team would get 3 lifelines or whatever they are called. Another alternative is to let the whole class have a go. Use it for some sort of reward then the entire class gets a prize or something. The lifelines can used to ask teachers in that case.
