I love this! Our class is really working on transitions. We do great until we have to move! Going to lunch, specials, even to the rug! *sigh* Hopefully something like this will help! We can use it for academic goals too!
To prevent unfinished work from being lost, have them stick in their front folder. When they have finished something else, recess, or at the end of the day, they can look in their front folder for unfinished work.
