These are signs to use to assess your students' knowledge as they walk out the door! These signs can be printed and then glued to different colored paper to hang on your door. The students write their name and one thing that "stuck" with them, or one thing they understand, and one thing they are "still stuck on," or one thing they don't fully understand.
It is very telling, and allows the students to think about their learning!
It can be used at all grade levels. Enjoy!
