Quoted from 85vett:Do you have a street light? If so, how much? My wife uses a red, yellow, green rule in her 2nd grade class and that would be neat to put in there for her to light up vs using paper.
Red - No talking, individual work
Yellow - Neighbor work and whispering allowed
Green - Free work and talking allowed
Here is a picture of what I had in mind.
I have several. One I'd let go of is about 42" tall. Black body and plastic. Retired from city of Pensacola.
