Very visual and easy way of alerting others that you are testing. I print off several of these at the beginning of the year and leave them on a shelf right near my door for easy access. As a Special Edu teacher it seems like I'm always testing, so there are really handy!
I am a Special Education teacher and work primarily with 4th grade, but you never know what other grade level may be added to my case load through out the year!
This is my 7th year teaching - wow has that time flown by! I work in an integrated co-teaching environment and resource room as well.
I hope that you find my materials useful to you and that they benefit your students.
