Measuring Time - Understanding Check

When looking at Chronological Order, does the order go:

BIG BCE -- SMALL BCE -- SMALL CE -- BIG CE

• TRUE

• FALSE

When finding Years Between:

What do you do when the date labels (BCE or CE) are the same?

• ADD

• SUBTRACT

When finding Years Between:

What do you do when the date labels (BCE or CE) are the different?

• ADD

• SUBTRACT

When finding Decades Between:

After you added or subtracted the number, what then do you have to do?

• Divide by 100

• Divide by 10

• Write down your answer

• Multiply by 10

When doing Years to Century:

What do you do when the date DOES NOT end in TWO ZEROS?

(Ex: 1991 CE)

• Get rid of the last two digits and write down the remaining number

• Get rid of the last two digits and add one to the remaining number

• Add all the numbers together

• Round the nearest century

When doing Years to Century:

What do you do when the date DOES end in TWO ZEROS?

(Ex: 1900 CE)

• Get rid of the last two digits and write down the remaining number

• Get rid of the last two digits and add one to the remaining number

• Add all the numbers together

• Round the nearest century

When doing Century Years:

How do you find the starting and ending year for a BCE Century?

(Ex: 10th Century BCE)

• Add two zeros to the number to get the STARTING YEAR and subtract 99 for the ending year.

  (1000 BCE - 901 BCE)

• Add two zeros to the number to get the ENDING YEAR and subtract 99 to get the starting year.

  (901 BCE - 1000 BCE)

When doing Century Years:

How do you find the starting and ending year for a CE Century?

(Ex: 10th Century CE)

• Add two zeros to the number to get the STARTING YEAR and subtract 99 for the ending year.

  (1000 - 901)

• Add two zeros to the number to get the ENDING YEAR and subtract 99 to get the starting year.

  (901 - 1000)

How confident do you feel about the Measuring Time Assessment?

• Really nervous, think I am going to fail.

• I need to continue practicing but I think I can get it.

• Confident but still worried about some things

• I will get an A for sure!

Which of the following areas of Measuring Time are you most confused about?

• Chronological Order

• Years Between

• Decades Between

• Year to Century

• Century Years
