If I could figure out a way to create something similar for Hall Rules, except in Spanish, then this would be applicable to my class. A good way to manage student behavior in the hallway when they are a part of your class at the moment.
For teachers: Do you ever have a student that just needs to get out of the room for a minute and get a new perspective? Give them "The mysterious envelope" to deliver. (I like the "mystery student" idea too)
Classroom management tool - It can be soooo time consuming to answer the questions.Can we use markers?, Do we turn this in?, Is this a talking activity? I love using these assignment choice signs to answer those questions without me doing the work.
