These are similar to the whole brain teaching posters. There are 10 options of different attention getters to display in your room. I usually only pick about 4 and use them throughout the year, though with some classes variety is good. I would suggest laminating them and posting them somewhere student can access them. Teacher says top words, students answer with bottom words.
All Set...You bet!
Hands on Top...That Means Stop (Students put Hands on Heads)
Winner, winner...Chicken Dinner
Hocus Pocus...Time to Focus
and several more.
