Rule for the teacher: Select the situations for the particular grammar item you are going to present. Look through the textbook and other teaching materials and find those situations, which can ensure comprehension and provide the usage of the item.
Different approaches to the teaching of active grammar (grammar for conversation) and passive grammar (grammar for reading). Grammar items pupils need for conversation are taught by the oral approach, i.e. pupils and them, perform various oral exercises, finally see them printed , and write sentences using them.
Grammar items necessary for reading are taught through reading. (E.g. The Past Continuous). At present they do not need this tense form for conversation. They need it for comprehension of the text only.
Rule for the teacher: If the grammar item you are going to present belongs to those pupils need for conversation, select the oral approach method for teaching. If pupils need the grammar item for reading, start with reading and writing sentences in which the grammar item occurs.
In short new grammar it, may be introduced in two ways: a) inductive; b) deductive. Inductive way means to observe grammar facts (phenomenon) in the texts, to select them in the speech situations and generalise them. Deductive means giving some rules or presenting in the form of speech patterns, then pass over to examples, exercises and so on. If necessary both ways are possible to use at one lesson. Choosing this or that way of presentation of a grammar item mostly depends on:
the character of the grammar item to be presented;
For example, The Past Continuous may be easily presented and introduced on the base of Present Continuous (inductive way).
Translation method will do well if grammar item has its coincidence in the mother tongue.
