After a long day at school, teachers will often find their last class of the day largely not engaged in learning or paying any attention at all, which can be a very frustrating experience, both for them and for the students who are willing to learn. Keeping them engaged therefore becomes of paramount importance.

Doing this is more easily said than done, with many of the techniques which teachers tend to rely upon in a normal class failing when there are so many students not prepared to do anything at once. One of the best ways to do it is to make sure that you time your intervention correctly; the earlier the better. A lack of attention to the subject at hand is often contagious, so tackling the issue when it is just one or two students can stop the spread, so to speak.
