Start with the everyday classroom resources. You might set an example this month by creating a timeline of events in the life of Martin Luther King. Read an encyclopedia account of his life and create a general timeline. To celebrate Presidents Day, create a timeline of events in the life of Abraham Lincoln or George Washington. When completed, students can share their timelines with their classmates.
Newspapers are excellent sources of information for timelines.
Follow events of an important national news story as they unfold. A quick scan of USA Today revealed some recent possibilities for creating news story timelines. Or create a timeline to document newspaper stories about El Nino. Several Internet sites are devoted to historical timelines. But if you're looking for resources on a particular topic, just plug that topic into your favorite Internet search engine to find valuable resources.
