I subbed today for 5th grade teacher.
It was a fun day. I spent about a half hour read poetry to the kids. I loved it. They loved it. It was even part of the lesson. A good time was had by all.
Teachers: I completely understand that emergencies happen, and there are days when you can't put out materials for a sub ahead of time. However, on those days when you have to email in your lesson plans, please don't write them to suggest that the day's materials are out on your desk. Or, if that particular wording is static in your plans, at least make an additional (very specific) note as to where to find things. I don't mind digging through filing cabinets, or even making copies, but guessing at the worksheet you want, based only on what the board says the kids did yesterday is not helpful for anyone.
