My kids have a homework journal they have to take home each night and have signed as well as I have to sign it before they leave each day with the daily homework written down in it!
I especially love this for students that are absent so that they can look to see what assignments they need to catch up on!!!!
Another thing I do is put TR for Thursday for outside of the classroom education...We discuss at the beginning of the year how this is used in college to let you know what day your classes will be on!
They love that concept!
