This a huge list of attention grabbers to use with elementary age kiddos. I have used them with 3rd and 5th grade and they love them! Each day, I draw a student's stick from my classroom cup (one per kid), and they get to choose the attention getter for the day. These keep it new exciting. The teacher says the left side, and the students respond by stopping and giving their attention to the teacher and saying the right side. Here's a few:
Houston... we have a problem
There's a snake... in my boot
Vote... for me
If you purchase it and your students think of a new one, let me know! My kids have added to the original list throughout the year.
