The teacher writes a sentence on the board. Students, in teams, decide whether the sentence is Correct (C) or Incorrect (I) and hold up the appropriate letter on a pre-made card. The teams who raised the I card must write the correct sentence on a piece of paper and hand it in to the teacher. If the sentence is correct, the team scores a point. If the sentence is still incorrect, no points are given. If the sentence was correct, the teams who raised the C card get points.
