Here are some Internet sites that allow you (and of course your students!) to create time lines. What a great possibility for students to creatively exhibit their mastery of a sequence. This can be an event or era in history, a biography, a plan, or something that I haven't thought of yet! Most also allow embedded images or even videos. Feel free to add other sites you know of.
