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.
I like having all the activities to choose from when we work through a chapter. But it is a little hard to know WHEN to use the activity. I thought it would have more of a plan but I guess that is left up to the teacher. We read from the book and then do an activity and then read more. But we may try reading the whole chapter first and then using the activities for review.
