As I'm thinking about next year (I love to plan ahead!), I'm starting to think about how I maintain student portfolios. Our district requires a folder for each student in reading, writing, and math, with work samples put in each. I feel like I hoard too much. How much student work goes in your portfolios (or folders like these, if you have them)? Like one piece a quarter, etc? There's no hard-and-fast way to do these in my school and district - some people are like me and put everything in there, and others have one piece for the whole year(!).
