This is a great way to review mechanics with Spanish heritage / native speakers. Students fold their paper so they can only see the lines for number 1 (not the text). Teacher reads the sentence(s) for number 1 two times (or more, depending on what you are going for). After the teacher has repeated the sentence(s) the given number of times, students slide down their papers so they can see the answers and make corrections (in this case, they should be focusing on punctuation corrections). Then the teacher moves to the next sentence.
