Odd One Out: choose an answer and defend the rule.
Show four items and ask students which one does not belong. The best answers are not always the obvious ones: students should justify the rule they are using and respond to alternative arguments.
Odd One Out
Pick the odd one out, then defend the rule.
There may be more than one valid answer. The point is not just to guess; it is to explain the rule that makes your choice different.
