For those who are required by state to keep portfolio... what do you keep? Just the best samples? or do you keep work they stuggled on to show improvement? I was basically just keeping all her workbooks but at the end of first grade, I'm realizing thats going to take up a lot of space, especially x3 kids. I want to get creative about it, but I want it to be simple and straightforward. Like, I'm using Math U See now, I was thinking of just keeping her tests for the end of each lesson. Any tips?
