This might seem elementary.but I love the quiet spray idea! Very cool teacher ideas on this site. Quiet spray has nothing in the bottle but air. This may be the smartest classroom management tool I have ever seen.
Put your student's names on the back of YOUR name tag. This will help you during a fire drill, tornado drill, and earthquake drill so that you won't have to worry about finding the class list. Most brilliant idea ever.
Put a class list (on cute paper, of course) in a picture frame. Use a dry-erase marker to mark students off of a list! Add a line at the top of the page to remind you what it is for. Field trip money, papers signed and returned, etc.
