Good product overall. Difficult for for younger elementary students - there is quite a lot of free-hand note taking space without any instruction really. My younger kids aren't able to do that yet. Wish there was a little more structure and instruction, but we are using parts of the product just fine. I am creating true/false worksheets which utilize the vocab words for co-op kids to fill-in some gaps in the journal. Would buy it again though, just for the parts we are using, but only at a great price.
My 6 year old daughter loves this notebook. She could not wait for summer vacation and school to end. She loves this so much we have started it now to study the insects during the summer. This is not "school work" this is fun! I love the fact that you can use this for any age! It works for all. The best curriculum I've seen.
