Scribblemaps is a fairly simple tool that uses Google Maps and tools such as the ability to add text, images, shapes and so on.

Students can easily map where the action in a book takes place, add an image of the cover and perhaps some images of the suburb or city where the book is set. Maps can be saved and accessed later but it is vital that the code on the address line is saved for the next session. Students do not need to register for the site, but need to enter a password and keep track of their map codes. Scribblemaps is available in twelve languages.

The best part of Scribblemaps is how easy it is to use.
