Annette,
It was good to meet you! I think one of the phrases you are referring to is when Andrea taught us how she interacts with her Kinders on Rule 5.
T: Rule 5
ST: Keep your dear teacher happy
T: And what keeps me happy?
ST: When I learn! I need to say it, and do it, to learn it!
(Gestures were hand by mouth as if you were speaking, roll hands in front like you are busy, and touch your head to indicate learning).
As for the scoreboard, just ask your students to "hold it" until you point to them. That way you can have the "Oh Yeah" all together.
Have fun!
