1. Objective: Today students are going to study Ancient China and revisit how to read a timeline. • Bellwork: Powerpoint. Please have out your classwork from Friday as well. • Agenda: Review how timelines work. Take quiz. Continue worksheet. Go over worksheet. • Content Standard: 7 – H1.1.2 Compare and contrast several different calendar systems used in the past and present and their cultural significance

2. Reading a Timeline: Revisited

3. What is a timeline? • A timeline tells a story of what has happened. • It displays things in chronological order (in order of events as they have happened.

4. Timelines have two sides • The Left Side: • BCE-Before the Common Era • BC-Before Christ • This is because the calendar used in the United States is a Christian calendar. • The Right Side: • CE-Common Era • AD-”In the year of our lord”

5. Think of timelines like a… • Number line. • A number line is a line with positive numbers on one side and negative numbers on the other. • On the negative side of a number line, the numbers count down to 0. • On the positive side of a number line, the numbers count up from 0.

6. Timelines do the same. • Think of BCE as the negative side and CE as the positive. • Remember to look for the “B” in figuring out if you add or subtract. • One “B” means add. • Two “B’s” mean you are on the same side. • Subtract when you see two of the same abbreviations. • Not to confuse you, but there is no year “0.”

7. How to tell the distance: • If time goes from BCE to CE, you must add that time together to see how long ago it was. • For example, if something happened in 500 BCE, it really happened 2514 years ago because we live in the common era today. 1 CE 500 BCE 2014

8. How to tell the distance cont’d: • If something happens on the same side of the timeline (meaning it does not cross year 1), then you simply subtract it. • If something happened in 500 CE, it happened 1514 years ago. 500 CE 2014 1CE

9. About how long ago did the Zhou begin ruling? • 2000 years • 3000 years • 4000 years • 6000 years

12. IF the Xia quit ruling in 1700 BCE, about how long ago did the Xia quit ruling? • 100 years ago • 3200 years ago • 3700 years ago • 5000 years ago

13. If I was born in 300 BCE, how old am I? • 1714 years old. • 2314 years old. • 1314 years old. • 1614 years old

14. If Christopher Columbus came to America in 1492 CE, how long ago did he come here? • 522 • 422 • 322 • 122

15. If the United States made in 1776 CE, how old is it? • 238 years • 438 years • 338 years • 138 years
