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

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

4. 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. 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. 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. 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. 2014500 BCE 1 CE

8. 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. 2014500 CE 1CE
