Timelines

​Did you purchase a yearbook in your previous school?  Yearbooks are used to preserve special memories that happen during a particular school year. 

If you purchase one each year, it gives you a way to look back and remember teachers, friends, and fun times long after they are over. 

In a way, yearbooks create a timeline of your life. 

​A time line is a visual that shows when events took place. We use them to figure out the date, or when, an event happened. Time lines are always written in chronological order - the order in which they happened.

• title - this tells us what the timeline is about​

• time - these will typically show the dates, or years, ​of the events being shown

• Events - brief descriptions of the events; we do not need complete sentences

• ​Many timelines incorporate color to help further organize information

A timeline shows a vertical or horizontal line with marks on it. These marks are meant to indicate time intervals. These could be intervals of minutes, one year, ten years, a hundred years, or any other interval, depending on the purpose of the timeline. ​

​This timeline shows intervals of minutes and hours because it's scope is just one day.

​We can also interpret, or answer questions, from timelines. For example, I can see that Ben Franklin invented swim "hands", or fins in 1717. But we can also answer more complex questions, by closely reading the dates. For example...

Historians divide time into centuries and decades to make it easy to study. 

 
A decade, century, and millennium are units of time that represent specific periods of years: 

Decade: A period of ten years. For example, 1980 to 1989 is a decade. 

Century: A period of one hundred years. The word century comes from the Latin word centum, which means one hundred. 

Millennium: A period of one thousand years. The word millennium comes from the Latin word mille, which means a thousand.
