2/28/13 • Entry Task • What is a TIMELINE?
Discuss Answers • A timeline is a graphic representation of the passage of time as a line. Either vertical like facebook or horizontal… • EXAMPLE • http://1.bp.blogspot.com/-zr2Mh-uoWfg/T6BQf69mDLI/AAAAAAAACmk/l_QQlVJ-sis/s1600/Timeline_Inventions.jpg • Often, past on the left…current on the right. • Remember the spaces on the timeline should be even. For example if you want to span 200 years over 10 inches, every inch would be 20 years.
