I started with the class-yes and my students loved it! http://www.wholebrainteaching.com/Whole-Brain-Teching/First-Steps/Attention-Getter-Class-Yes.html However, I needed to add my own special touch to it. I came up with Yo Yo- What's Up. When I say Yo Yo my class says what's up. This is a great way to relate to my students at their level. Using slang in a good positive way.....try it out!
