I recently received an email from a parent who wondered how unschooling worked with a child that could not yet read or write (her child was currently in public school Kindergarten and struggling). Here was my reply:
Unschooling works wonderfully for children who cannot read or write yet. First off, there are so many other ways to learn: videos, hands-on, board games, hikes, etc. Secondly, YOU can read to him whatever he desires read or you can use audio books (a staple for my son who was a very late reader – we’re talking 14!). Thirdly, you can write for him. If he has a story he wants to tell, etc., he can dictate to you and you can write or type it.
You might find my article about Teaching Kindergarten worth reading.
