Have you watched the SW video that was recently posted in the SCM blog? It really helped me understand the process better.
Tristen has also posted in previous threads about how she uses SW. That also helped me a lot.
What we do is
Day 1 – copy the selection in best writing with no errors
Day 2 – select the new words, there should only be a few that are new to the student. I have my child write down those words and look for phonograms and different things that help them understand how to spell the new word.
Day 3 – ready for dictation. I “spot check” ask a few words for her to spell out loud to me before doing the dictation.
I do not have my student copy the passage over and over. I feel like that would get old fast and the attention would be lost so it would be copying thework but not thinking about how the words are spelled.
I was never a good speller, but I could spell outloud much better than on paper. My DD does that too. Often after dictation if she gets a word wrong I ask her to spell it out loud and she gets it. I think she writes faster than her brain 🙂 Also she does her copy work in cursive but dictation in print. Print makes her slow down to write so that helped.
