Hey Im jenny and go to an International School!
We're going to have a graduation assembly in just over a month and I've been choicen as the 'organizer' of this event!
We've got some ideas like a powerpoint presentation with pictures of us as babies, then during our school years and then what we might be in the future! Also we'll be sayin our goodbyes to the teachers and giving small gifts and so forth...

I need some more ideas because these are the basic's that pretty much happen every year...
And we're not much of an active class!

My question is what other fun activities could we do during our assembly apart from this?
Any fun ideas that can involve the audience???
