I am working on a timeline project for my library. I am using www.tiki-toki.com to create an interactive timeline.
Their website states “Timelines offer teachers a fun and engaging way of teaching children about historic events. Kids nowadays tend to be very computer literate and may therefore get more out of creating a timeline about a particular event in history rather than simply reading about it in a book.” http://www.tiki-toki.com/faqs/
Tiki-toki offers a free version and you don’t have to download any special software.
