About this tool

Present a list of sentences, some correct and some with a grammar or vocabulary mistake tucked inside, and let teams bid points on the ones they think are right. Once the bidding closes, reveal the answer and the board sorts out who gained points for a smart bet and who lost them for guessing wrong on a flawed sentence. It turns grammar correction, usually a quiet worksheet task, into something teams actually argue and strategize over. Load your sentence list before class and run the whole auction from the front of the room.
