Various aspects of grammar have come into play in activities so far, though they haven't been focused on. For example, when the Nurturer describes what "he", "we", "you" etc. are doing at the moment, that is dealing with an area that is traditionally treated as grammar. In fact, much of grammar need not be thought of as "grammar", since it is simple a matter of how to express concrete meanings. The emphasis on possessive forms in today's session is another case in point.
