A while ago I posted about giving the kids "Primary Pox" where they got dot stickers put on them if they were singing. This time I switched it up a bit. I got a double sided poster board and drew a girls face on one side, boys on the other. Then I handed out a few stickers to each kid (or had the teachers pass them out). Then as they sang well I pointed to kids and they quickly came up and put a "pox" dot on the other teams (girls vs boys) face, to see which one would be covered quickest. I think the only this I'd have changed is that I needed to use bigger dots, so it would fill up faster!
You could use this idea with a bubble gum machine drawing, where they try to fill up the machine.
