This is one in a series of booklets which can be used by the teacher or a substitute teacher. Each booklet starts with a list of the vocabulary necessary to complete the booklet. Each booklet offers a variety of activities. Pupils can work through at their own pace. The activities will help the pupils to learn the vocabulary of that topic.
I have made these booklets to leave for classes I have to miss due to meetings, illness etc. I have also used them myself when I just need a class to get on with something.
Substitute teachers, even non-linguists, have reported back to me that the booklets work very well. If a pupil gets stuck the teacher can always find the answer in the booklet.
