If you’ve been avoiding building your own classroom timeline or centuries book you might want to consider having a look at this app.
This app is an extensive and wide-ranging timeline where you can drill down in time to a fraction of a second! Rated for ages 9 and up, I think older kids will enjoy browsing the graphics and the fun facts with links to other resources.
This app includes Natural History, World History, US History, Science and Technology, Art and Architecture and Sports.
Hope you enjoy it!
