Math Journals

I have decided that some of the best teaching resources come from our school's copy room.  Seriously.  I'll see something on the printer, or laying on the counter, and have to find out whose it is, how they use, and if I can copy it please!  The reverse happened last week when a brand new teacher was looking at a couple of my math Quick Quizzes that we use every Friday.  She asked me about it and that led to telling her about my Math Journals and how I use them.  I started math notebooking several years ago, after coming across some good research about them, and have been tweaking and perfecting each year.  I love that everything is in one place-assessment results, math notes, curriculum resources, standards, etc-and that the kids know exactly where they are in their learning, how to improve and in what ways. 

 I've noticed that the trend is catching on and now there are a million different ways to implement them.

How do you use math notebooks in your class?
