I give freelyand you are welcome to use this Presentation, in your class to spreadthe wonderful message geography gives. Downloads are often in the hundreds and I am sometimes asked if a donation can be given. The school and village sends and receives children from Tanzania on a two yearly basis and I like to help with their fundraising. If you have saved this power point or tucked it away to use next year and could make a donation that would be fantastic; the same as it might cost you for a tune for your I pod, say 49p. If you want to use it for lots of classes and keep for each year how about 99p. If only half of the down-loaders give we could raise the £1500 it needs to build a class room in Tanzania.

A little of our disposable income goes a long way in the developing world
