The Montessori approach has a pretty neat way of teaching grammar using manipulative symbols. They get introduced in the Grammar Farm (which is still one of my favourite Montessori lessons) - I show you how to introduce the grammar farm HERE and the printables are HERE. It is a while since we have done any grammar work so we started off really just doing a review of the parts of speech.
First matching the symbol and the part of speech...
black triangle - noun
small light blue triangle - article
dark blue triangle - adjective
purple triangle - pronoun
green crescent - preposition
red circle - verb
orange circle - adverb
pink rectangle - conjunction
gold keyhole - interjection
Once he had got the hang of that, I introduced sentences and he had to match the symbols with the words in the sentence. It's amazing how quickly he picked it up again.
The next step will be for him to write the sentences and draw the symbols and I am hoping he will also make a grammar book. I'll share the printables to go with this soon (like, when I finished making them!)
Ebi-kun did ask me what the point of learning grammar is - I have no idea! Do you?
