This YouTube playlist compiled by 4 One More is a lifesaver if you have middle or high school kids studying world geography. It’s an extensive (although not exhaustive) list of great video for every region of the world explaining the geography, the political situations, the history, and the culture of the place.
You can use this playlist no matter which curriculum you are using. You just need some type of spine for your studies – an Atlas, a pile of library books, a geography text. Most of it is on the middle school to high school level, as some videos discuss geopolitical issues and current events.
