Never read the book, but for us the transition to independent work is VERY gradual – usually beginning in about the 2nd-3rd grade.
Copywork is the first subject I generally train them to do independently. We set the timer, they are instructed to do their very best work until the timer goes off. If they have a language arts program, that generally comes next as far as independent work. Math would be last. All of this seatwork gets checked subject by subject, until independent work is natural. Then the entirety of their seatwork can be checked as it is completed.
Once my kids are reading fluently (about 3rd grade, usually) they are assigned independent book reading in the afternoon. I start with having them do a narration every day of their reading. Once I know they are comprehending well, I go to more occasional narrations.
The last subjects for us to transition are the family subjects like History, Read Aloud, Science, Bible, etc…We are now transitioning my 6th and 7th graders to almost complete independence in those areas. I would say that this is where the assignment checklists and written narrations really become necessary.
Some things we will continue to do as a family, forever! Devotions, Hymn Study, family read alouds, picture and composer study, nature study…these are things that have just become part of our family ‘atmosphere’ and I hope we will continue as long as the kids are at home.
Hope that gives you some idea of what we do around here and what a typical transition to independent work might look like!
