This Sunday (or next) have your children trace their RIGHT hand on a piece of paper.  Have them write their name on it and their favorite song (or something to help them CTR).  In February, put all the paper hands on the board and you choose one of the RIGHT hands. Have that child come up and be your RIGHT hand helper while everyone sings that song.  If they didn't write their favorite song let them tell everyone how they can choose the right.
