StoryMapJS is a free tool to help you tell stories on the web that highlight the locations of a series of events. It can be scaled large or small- the map will expand as you add additional sites and stories- and digital citizenship is built into the design. Every piece of media that a student adds to the map is encouraged to be cited and captioned!
MyHistro was designed on the same foundation of combining maps and timelines as of the one-of-a-kind history site Histrodamus. Unlike Histrodamus, though, you can create your own storymaps and share them with others in MyHistro.
