We used these Journals about two years ago, then thinking to save I didn't order them last year. Our children really missed them. These journals offer a lot in the way of review activites. If time is short pick a few and move on. I found my children often enjoy doing the extras on their own. The lessons really stay with them better after working in their journals. I would highly recommend these companion journals for the Apologia Science books. I am not the creative sort, so these are a big help.
We are finding this journal a good tool to keep us on task with reading through the textbook and different assignments. With multiple options, it gives us a variety of ways to apply what is being learned.
