If you are into Math notebooking, or want to be, Teaching Mathematics with Foldables is an excellent resource to use to get started. It has photographs and instructions for making various types of foldables/shape books and it contains detailed tables with specific activities (define, classify, explain, match, etc) for ver specific math concepts.
If you've been scratching your head as to where to get started, you definitely want to download this resource (free). I knocked out a handful of them yesterday alone for math, science, and even writing.
