Saw this over on schoolswork.co.uk:
Here’s a brand new website created by people who are dreaming of a more ethical Christmas, one which is a bit kinder to the planet and helps to spread peace and goodwill to all people! There’s an ethical gift guide, an opportunity to make a pledge and join the movement, as well as an assembly and lesson ideas for schools, resources for churches and more. Visit Free Christmas! to find out more.
I had a quick visit, and there certainly seems to be ideas that can be ripped for those Christmas sessions coming up.
