Find the Mistake

Find the mistake in the sentences.

There's a number of ways you could do this with your class, depending on sizes, maybe just having them put their hands up and giving points being one.

My class sizes are large, so I'll put them on teams.I'll either give them whiteboards and give them a minute to discuss and then give points to all the teams with correct versions of the sentences, or let them all look together and put their hands up when they think they have the correction - one guess per team per round.
