Notebooking is easy! It is basically journaling what you are learning. I discovered Notebooking pages a while ago. Debra has created hundreds and hundres of templates that fit into basically any subject or topic. There is something's amazing that happens when you give your kids cute templates with small manageable spaces for them to write. It is kind of like small bite chunks.
To note book, you pick a topic and read and discover and enjoy. Then you grab one of the sweet, cute, or appropriate templates and have your kiddos write about what they have learned. Voila, Notebooking.
I do a lot of copy work, narration and dictation with my boys. These templates are perfect! They appreciate using visually "cool" paper. Honestly, so do I.

You should totally grab a few of the free samples and see how they work for you!
