I found the following idea posted on the NACELL forum. A language teacher is suggesting this lovely "comptine": J'ai un gros nez rouge for children to sing and mime on the day; as a good "opportunity to incorporate a little language into everyday classroom routines". You can find other songs on http://ram.de.la.charabiole.free.fr/comptines/sommaire.html
you can also print an illustrated version on http://www.teteamodeler.com/vip2/nouveaux/expression/fiche195.asp.
Here is the link to a video http://www.youtube.com/watch?v=2YLr43CLKWc
A little late for this year but well worth saving!
