Google Maps
maps.google.com
This website is familiar with many, however, not as much as a learning tool. Maps shows roads and resources in your city, or anywhere in the world. It also shows directions to and from locations.
I would use Google Maps when teaching about the community. For elementary students, learning about their community would be easier if they could see where they are located in relation to the resources around the community. They could interact with the environment using google maps to find things in their community such as grocery stores, a firehall, etc.
I think this could help learners that are often bored by reading or listening to the teacher speak. Learners who enjoy visuals or hands-on would benefit greatly from interacting with google maps to forge their own understanding of community.
There is no age limit on google maps; however, I would see this being used in a grade 3 classroom or above as google maps can be a little complex for the younger crowd.
