I have to admit that one of my pet peeves is hearing every detail of what went on (especially with my not-so angelic students) when I am out on a sub day. If I'm out I have already spent a lot of time prepping sub plans and materials, or I'm stressing because I had to call in sick (which I rarely do). So, to make it easy for me to get a quick and dirty run-down of what went on the day I was out - I ask my subs to fill out the Substitute Report at the end of the day and to make notes in the margins of my sub plans. It makes for an easy transition back to work and I am always pleasantly surprised when students are listed as especially helpful. I love being able to give them an extra little reward (sticker or praise) for rising to the top while I was away. I usually print them on fun colored paper and keep them in the back of my lesson plan binder so they're always handy. I attach one to the stapled sub plans I leave. I made this one generic, so you can program in your school/name/grade before you make copies.
