Balloon debates are an active assessment strategy whereby students are asking to think or to discuss which character they would like thrown out of the balloon, and why. So it's a variation on odd-one-out and is a potentially powerful way to stimulate engagement and debate.
For example, in an English/Literacy lesson, that characters names might be from a particular text or they might be to do with grammatical terms e.g. Full Stop, Colon, Semi-Colon and Hyphen. In a Biology lesson, they may be: Heart, Lungs, Brain and Liver. Who should be thrown out of the balloon and why? There is not necessarily a right or wrong answer - is the engagement with the concept which is most important.
