This is the age when we can begin gradually of course to teach the rules of grammar and syntax, for the child is now reaching a point where he thinks not only about the world, but about himself as well. To think about oneself means, so far as speech is concerned, to be able not merely to speak instinctively, but to apply rational rules in speech. It is nonsense, therefore, to teach languages without grammar of any kind. If we avoid all rules, we cannot impart to the child the requisite inner firmness for his tasks in life. But it is all-important to bear in mind that the child only begins to pass from consciousness to self-consciousness between the ages of nine and ten. To teach grammar before this age, therefore, is absolutely irrational.
