106 Days of Creation

OK so I have my daughter in 3rd grade and I’m wondering, when we finish the 106 days of creation, what do we do for 3rd grade? Do we repeat it then? Just adding new books? I’m a little confused. How do we know when to move to the next book? And how to we know if the books to the right should be used? I mean like the book “yellow and pink” for example, is that just for younger kids or do you use all those with the older kids as well?
