"Da capo!"

To make repetitions less like practicing (and teach the meaning of da capo), rather than saying, “Let’s begin again,” smile and enthusiastically say “Da capo!” using the rhythm "blue jello" as you tap your head with both hands. Motion for the students to join you a second time and everyone taps their heads in rhythm with both hands saying, “Da capo!” This is a good time to give a few words of encouragement to them. After a moment, begin singing “Daily Do” from the beginning and they will imitate you. Thus, whenever you feel more practice is needed, simply say, "Da Capo!". 

Although this short video is showing DS-2: "Daily Do" With Do Re Mi Cards, "Da capo" is used with any "Daily Do" game.
