Tamara did an awesome job of explaining this - ditto to what she said! Once you have the DITHOR manual in hand, you'll understand this all better. Here is a link to DITHOR's Introduction, and if you arrow down to the "Program Structure" section, that may be helpful as well:

Just remember you have 15 days of reading for each genre, and 5 days of a final project for each genre, which together equals 20 days of plans for each genre.
That is why the reading calendar has 15 days of reading you write down pages for at the beginning of each genre. The reason you choose from the below options is because there are "prereading" activities in the DITHOR plans, which make it a nice place to begin a new book if you choose more than 1 book:
1. read 1 book for the whole 15 days
2. read 2 books, spending 5 days on one of them and spending 10 days on another
3. read 3 books, spending 5 days on each book
We have split up 2 books more evenly before, reading 1 of the books 7 days and the other book for 8 days to = the total 15 days, and it has not been a problem. I view the "prereading" days as either prereading a new book, or prereading for the next part of the book you are in the middle of - then it works out fine.
Still, the point of the 1- 3 books and 15 days of reading + 5 days of final project is that books are meant to be enjoyed, savored, given adequate time to - not rushed through. We've found sticking to the 1-3 books to be a wonderful way to linger with reading great books - it is why our dc remember their DITHOR books more fondly and with more clarity than any other books. HTH! Just wait until you get the DITHOR manual, student book, and sample book ideas list - it will all make sense - and if it doesn't, just keep asking away here!
In Christ,
