I LOVE how accountable this simple form makes my students. They get a new one to keep in their reading workshop (center) folder each Monday and I collect them for an easy classwork grade on Friday. Sometimes I photocopy an actual piece of work I'd like to grade on the back, for easy collection/grading. Students take about 1-2 minutes each day after workshops to fill in what they did and one thing that they learned (or practiced- because of course they'll argue that they didn't learn anything new). I have also added a spot for students to reflect at the end of the week on where they are with the learning goal. This can be edited to fit the needs of your classroom and can be used in math centers as well (as one of my students suggested)!
