How Do We Measure Time?

• Time, as we usually use it, is measured in years BC and AD.

• BC (Before Christ) counts the years before the Birth of Jesus.

• AD (Anno Domini) counts the years after the birth of Jesus.

• Now in History we usually use the term BCE (before Common Era) instead of BC and CE (common Era) instead of AD.

Foldable Notetaking!

• We will be creating a foldable time with which to take notes.

• Hot dog fold• 2nd hot Dog Fold• Mark of five equal sections (about 1 ¾ in.)

with a pencil• Draw a timeline arrow across the length of the

foldable, and label it according to the diagram on the next slide.

Example

After copying the writing, use your scissors to cut each line, being careful to NOT CUT THROUGH THE BACK PIECE, this way the timeline will stay together.
