To warm up, give this worksheet to the student, read each expression, the student reads right after you (in a loud voice, so the student can be in touch with correct pronunciation). Then, ask the student: "What do you do 'once a week'?" And go on, covering all the expressions. This exercise might take 15 - 20 minutes. Be careful not to make the exercise annoying. And also contextualize the examples with the student world, I mean, things that they like.
