Digital timelines can be a great tool for teachers. Tiki-Toki has many features. You can add pictures to the timeline. And the events entered can be given very specific dates and times. The timelines can also be published online. Students could use online timelines to review for a test, or prepare for a class presentation.
http://www.tiki-toki.com/ is a site to make online timelines. This site would be great for students in grade 5 and up. This site is easier than other timeline creating sites but can be tricky at first to navigate. Teachers can use this site for any subject. If a class is learning about the holocaust, the students can create a timeline of the events that occurred during the holocaust. A math teacher can have their students create a timeline about mathematicians from a certain time period.
