The students are corrected systematically, as needed, to avoid fossilizing bad habits. Rather than telling the answer, clues are given so the students can resolve the problem logically. This helps the language make sense in their minds, and leads to fluency. For example, someone – teacher or student – can point on one of the charts to indicate the problem sound or word. Finger correction is also used extensively. Finger correction is similar to the game of Charades where the words of the sentence to be corrected are "placed" on the fingers, one word per finger. Then the teacher only has to wiggle a finger to show where the problem lies.
