This phase corresponds roughly to grades K-5. Children love to pretend and mimic. They are like sponges. Therefore pouring lots of experiences and information into them is necessary to soak that sponge. They love songs, poems and nursery rhymes, stories and commit them to memory with little effort. It is easy to give students the factual building blocks they will need for later phases through these ways. The grammar phase is concerned with giving the student a thorough foundation of all the facts of each subject.
Content is key. A child amasses all kinds of information: names of rivers, cities, mountains, stories of people and conquests, characters, plots, parts of speech, a history timeline, Shakespeare’s sonnets, dates, the pharaohs of Egypt, Chinese dynasties, the Declaration of Independence etc. – all in creative ways that come easy, thus creating pegs to hang and organize information. With an appropriate Grammar phase, you will not find that high school sophomore beating her head against a desk because it feels so laborious trying to memorize dates for a test. By that time, she already has that information that was stored away when it was fun and easy, now awaiting deeper thought and analysis of content.
Also, formal study of Latin begins around 3rd grade. Latin is studied because it is the root for 50% of our language and many other languages. Often one Latin word gives us, say, 14 English words. Our own way of labeling English grammar came from Latin and this language helps us have a thorough command of our own.
It is important to note, however that grades K-2 are recognized as a vital early childhood development period and together they are seen as somewhat distinct from the rest of the grammar phase. These first years allow for even more guided discovery, creative play and space to be a little child. There is no rush. Living in those small moments at the proper time will allow them to live large later.
