So let the kids read, which teaches real grammar. Let them hear the language – it accomplishes the same thing. Make sure that they understand it – that is your job. Don’t mention the names of the bricks of the family of bricks (stop dividing language into pieces of things) and allow the deeper minds of the students, not their conscious minds, to grasp how everything fits together. That’s how it works.
It is only the whole brain that can perform the nearly infinite functions necessary to grasp how the language is built. The conscious analytical mind is totally incapable of doing so. Just read and talk with the kids in the language. Point to the majestic design of the building of the language, which is far more beautiful than any building, even Garnier’s. And certainly far more majestic than any pile of bricks.
