This one is also another good site. Its a presentation about all the different Google programs and what they can be used for in a classroom setting. The cool thing about Google many of the programs are collaborative - for example a student could be working on an assignment he/she can save it on Google drive and we, the teachers can go in and change things right on the spot and they get it back immediately. Go have a look!
This would be an amazing website to help students with geography and to learn something new from real people from another country. When I have a classroom I will use this! It would be a great way to spend an hour in your classroom learning something that will stick with them.
