Frank knows that there are 100 centimeters in a meter. That means that the length of one centimeter is 0.01 or of a meter. Frank's pencil is 15 cm long.

1. What fraction of a meter is the length of Frank's pencil? Write this fraction as both a decimal fraction and as a common fraction.
2. Is the pencil more or less than one-tenth of a meter?
4. Ming's pencil is 2 skinnies long. He knows 2 skinnies is of a meter.

1. How long is the pencil in hundredths of a meter?
2. Ming showed how he counted tenths of a meter. Count the length of the pencil using hundredths of a meter.
5. How many hundredths of a meter is Shannon's super-long pencil? Tell how you counted the length of the pencil using hundredths of a meter.

Showing Hundredths with Base-Ten Pieces

Irma uses base-ten pieces to show hundredths. She learned in Lesson 2 that if a flat is one whole, then a skinny is one-tenth (0.1) of a whole and a pack is ten (10) wholes.

6. Which base-ten piece should Irma use to show one-hundredth? Explain why you chose the piece you did.
1. How many hundredths does a skinny represent? Write this number as a common fraction and as a decimal fraction.
2. How many hundredths do 4 skinnies represent? Write the number as a common fraction and as a decimal fraction.
3. How many hundredths does a flat represent? Write this number as a common fraction and as a decimal fraction.
