(Part 1 - Explorers / first part of page 1)
A long, long time ago, where you live now was only trees and grasses. The only people on all of this land were Indians. There were no towns or farms, as we know them. It was like that for many, many, years. The towns and farms were far, far away, in other lands.
(Part 4 - The Constitution / first part of page 13)
We all need rules. Laws are written rules. Rules and laws control actions and often settle arguments. They often guide people in how to act. Like one law uses a "speed limit" sign to tell people how fast a car may be driven.
Before 1776, all countries were led by Kings and Queens. They were not chosen by the people, but forced on them. Kings and Queens were the government. They led armies, wrote laws, settled arguments, and punished people. But in America, many leaders are chosen by the people to do all of that.
(Part 7 - Justice / first part of page 26)
When people do not obey a law they must face Justice. That means someone must say, or decide, what happens. In other countries that was a King, or King-like leader. They were the government, and punished those who did wrong.
But in America, Constitutional Amendments told of a new way to determine Justice.
