I used this idea in my primary singing time and it was awesome.

I had a blank poster board and (washable) markers up at the front of the class room. And papers hidden around the room. On each paper I had written two things. One the item they were to draw. And two, the song we are going to sing while they draw.  When it was a child's turn to find a paper they would bring it to the front. Then they would start to draw their item as soon as the music started. They would only have until the music ended to draw that item.
 

In the end we were able to go over all of our songs. And we had a fun picture that each of the children had participated in drawing. We gave our picture to the bishop to hang in his office so that all the children could go and see what they had done.  They loved it and it was so much fun.
