Explain that voting is a fair way for a group to choose, and count votes to find the winner.
When a group cannot agree, voting is a fair way to choose. Everyone gets exactly one vote, and the choice with the most votes wins.
Voting will not always pick YOUR favorite. That is okay -- it is still fair, because everyone had an equal say.
Mastery looks like: They can explain that voting is fair because everyone gets one equal vote, and they can count votes correctly to find a winner.
Common stumbles: Feeling that a vote was "unfair" simply because their own choice did not win, or miscounting tally marks.
