Germany: My students decorate a paper pickle (in Germany they hide the ornament in the tree and the first to find gets an extra present) with a google eye, santa hat and cotton ball pulled apart for a beard and hat trim, with small white pompom on hat.
I also read The Cobweb Christmas (how tinsil came to be put on the xmas tree)
Mexico: make a homemade pinata with students help and fill with candy.
I also print Christmas phrases in the different languages and play music as well.
We do the passports as well. Great fun! Enjoy.
