Variety

It is very important that you provide variety to your students in terms of content and methodology. Try to change your approach every once in a while and surprise them with new assignments, tasks, and even games. When changing your approaches during the lesson, the students are always on "alert" mode but it in the good sense of the word. They are anticipating and waiting for something new to happen. Their attention is on a high level and lets them understand and learn faster. Another positive outcome of frequently changing your methodology is that your student will not get used to the same cycle of learning following a routine which you've created for them. If they are channeling their learning into a routine, you become predictable in your teaching methods. They will know what follows next and will easily guess the answer, or the question, and will always be prepared to provide it when asked for it. This may skew your perception of their progress and you will not be able to have a proper indication of their needs.
