We've been working on Geometry this term so looking at grid co-ordinates and finding about about direction, rotation fits quite well with this unit. It's also a follow up to our camp earlier in the year when children were introduced to a GPS for use within a survival situation. The children had to find there way around the camp grounds picking up essential survival items along the way.
All that aside, how did I introduce it?
1. I used Google maps & Google Earth, I let the children loose in these two programs finding their own houses and different landmarks around our school
2. I set them a shape finding challenge, they had to find and label at leasst ten shapes in within the Auckland area including the geometric attributes within the description of the shape. Here is one of the maps they have created, they're still working on it. You will probably need to view the larger version of the map to get all the shapes they have included.

The idea for this and the following activity came from this blog post
3. Treasure hunt time, the children were introduced to GPS co-ordinates and we talked breifly about what they were. Then I asked them to find interesting parts of Auckland and mark down the co-ordinates for their classmates along with a question like - What happens here? or Why is this place important to....? We'll be sharing these soon as they aren't quite finished.
Any other ideas would be greatly appreciated. Are you a geocaching class? We'd love to hear from you, what you're doing, caches you've found etc.
