If you've homeschooled for long enough, you've definitely come across lapbooks. They are not only a way to organize what a student is learning, but they are also a record of what they've studied (learned) as well as a study tool to stay up on the information in the future. My favorite lapbook company is Knowledge Box Central, but you can also find them through A Journey Through Learning.
Lapbooks work for any age, and while the younger students might need help cutting their pieces out, or gluing them down, older students can do them completely independently. We loved using lapbooks with the Exploring Creation Series by Jeannie Fulbright.
If you haven't given lapbooking a try, what are you waiting for? Doesn't this look like a blast?!
