A Tisket A Tasket is another great game because the kids get to run in it and it breaks up the desk work. You could adapt it by letting the kids choose different things to 'drop' other than a letter.
Here are the instructions and lyrics for the game and you can listen to it sung at

There are other games there too.
Make a circle and sit on the floor. One child skips around the outside of the circle ( as in duck duck goose) as everyone sings
A tisket, A tasket
A green and yellow basket
I sent a letter to my love and on the way I dropped it
I dropped it
I dropped it
And on the way I dropped it
I sent a letter to my love and on the way I dropped it
I dropped it
When they get to the words 'dropped it' they tap someone
gently on the head and that child chases them around the circle back to their place.
Start again with the new child
