The way that home schoolers
might approach this, at least sometimes, is to have the child copy the
passage for copywork, then later analyze the passage for grammar (later
in the day, later in the week, or even the following week). Another thing
that many home schoolers do is use the copywork passage for dictation,
which is where the parent reads the passage and the child writes it, trying
his or her best to get spelling, punctuation and so on perfect. So
after using the passage for copywork and then grammar, the child could
then write the passage as the parent dictates it.
This is from the copywork of AO Year 6
