When singing with the children, there are a few important tips:
1. Look at the children.
3. Cue them at the beginning of the song, and sing with them.
Look at the children at the beginning of the song. It's better to memorize the song, but if you haven't, memorize the first line quickly right before you sing. That way at the moment it's time to sing you can see the children and the pianist and cue them to begin. Making eye contact is very important.
