Chronological Thinking: Interpreting Timelines
Studying timelines, which show events in the order in which they occurred, can be a good way to identify changes over time. Study the “Brief Timeline of the National Woman’s Party, 1912-1997” and look for ways in which the tactics of the suffragists changed over time. Write an essay on the changes that you note. Choose photographs from the collection to illustrate the essay.
