Review Timeline Labeling

• Years/Dates – are labeled with either B.C./B.C.E. or A.D./C.E. after the date is written/displayed.

• These labels will tell you if the date is before or after the zero.

767 B.C. 0 767 A.D.

767 B.C.E. 0 767 C.E.

Here is an example of how to create your timeline:

Lets Practice Making a Timeline

• With your group you will;– Draw a blank timeline on your piece of butcher

paper.– Place the date cards in order on the blank

timeline.– Rotate to the next group and place those date

cards in the right order.
