Here's one I remember from elementary school {the younger grades}
I call it the "Good Morning" song. I don't know what it's title really is but I still remember it was the song we sang after standing and doing 'the pledge of allegiance':

Good morning to you.
Good morning to you.
We're all in our places
with sun shining faces.
Oh, this is the way
to start a new day.

Of course, I sang this song to my children. They didn't learn it in school. I don't think they even had a Good Morning song.
