As a teacher I had a lot of things that I said over and over and over again to my kids... people used to laugh because I'd start saying something and the children would finish it.
Here are a few I used a lot
"direction given, direction followed"
"This isn't your house, and I'm not your mother"
"That doesn't work here"
"I don't think we are having a debate"
"When did you get to be the teacher?"
"4 on the floor or you stand" (4 legs of the chair on the floor or they lost the right to use a chair)
"That is a privilege not a right"
"Is that helpful or hurtful?"
"Is that a safe choice?"
"I don't understand the word 'can't'"
"Ask 3 before me" (ask 3 friends for help before asking me)
"Are you wasting my time?"
I don't have a lot that I say over and over with Blake... yet
"Is that safe?"
"What does a big boy do with ____?"
"give hugs to say sorry"
"thank you for making good choices"
"if you can't listen to mommy then ____"
So... what do you find yourself saying over and over with your own kids (or other teachers out there... with your classes?)????
