They should be able to now explain to you exactly what they do, they may not be able to tell you the subjects that they're doing, but that will come later on, but they can' explain weather, they sit or stand, whether they do their homework, whether they go home and do it, or they do it at school, and many other useful things that will help them progress in their English, and when teaching them, you should do this relaxing, make sure that there is no stress, this is a fun, entertaining book and they should be able to be excited and want to laugh and enjoy it with you together.
