There are several timeline tools available on the web. My favourite is Dipity; it's simple to use, collaborative and free.

My Year 5s have been studying the Victorian era in class, so in my rather short weekly ICT sessions with them I thought I'd try to put a bit of chronological context to their study. We've started by setting up a timeline of Queen Victoria's life. Once the children got the hang of adding an event to the line, they rapidly started to add the births of Victoria's nine children, important wars, deaths etc. They all worked on the same timeline concurrently and I wasn't worried if several children put the same event on the line - it allowed us to compare entries on the whiteboard, highlight common mistakes, and agree which was the best one. The remainder were deleted.
In the second lesson, I showed children how to add images and links, and I'm particularly pleased that all the images displayed are fully copyright checked and free.
