Hmmm interesting video. I agree totally with her ideas for encouraging writing, but have always had issues with invented spelling.
My older children learned spelling and I would mark their words incorrectly and encourage them to look them up. They are excellent spellers and also love to write.
My younger son has used invented spelling in school and spells very poorly (in grade 5) and is reluctant to write because he doesn’t know how to spell the words. He has asked me to teach him to spell.
What do you think?
