HISTORY

History is everything that happened in the past. History is important because we can learn from the past. We can understand why things happen in our world and use this information to make our lives better. 

We can use historical sources to learn about history. Historical sources are objects that give us information about the past. Historical sources can be photos, paintings, written documents, buildings or objects that people used in the past. 

We can use measurements of time to organize information about the past. 

· A year is made up of twelve months. 

· A decade is made up of ten years.

· A century is made up of one hundred years.

· A millennium is made up of one thousand years. 

We can divide history into five main periods:Prehistory, Ancient history, the Middle Ages, the Modern Age, and the Contemporary Age.
