You just go through the days for the genre once. You might have one book for the first 5 days and another for the next 10 days, but you don't go back to day 1 for the second book.

The workbooks are consumable so likely not okay to copy from and the teacher book is non-consumable and I think is okay to copy from as needed. You'll use the same teacher book, day by day, every year. The only DITHOR copies I made were the record keeping pages for who read what books and when, "tips" pages, and the vocab, etc. worksheets all from the teacher book. I was a bit confused at first on how to do things, so maybe the copies weren't needed (or allowed!

) but that's how I understood it.
