Unit 6: Length
Chapter 1- Examples of test questions:
Be able to estimate and measure lengths to the nearest meter and centimeter. Students need to have an idea of the length of their arms, hands, or feet, or width of their palms or fingers to help them estimate length in other objects. For example, if the width of a finger is 1 cm, they can estimate the number of fingers-wide an object is. This helps them to estimate its width in centimeters.
Fill in blanks with ‘m’ or ‘cm’.
- The low bookshelf is about 1 ___ high.
- A door is about 4 __ high.
- A notebook is about 1 ___ thick.
What would you measure with each: meter stick or ruler?
- length of pencil
- Fill in blanks with ‘m’ or ‘cm’.
1 m = 100 cm
- Write 6 m in centimeters.

Chapter 2- Examples of test questions:
- The kilometer is the standard unit of measurement in the metric system for longer distances. 1 kilometer = 1000 meters.
- In the U.S. standard system, miles are used to measure longer distances. A mile is longer than a kilometer. 1 mile equals 1.6093 km, 6 miles is about 10 km, and 60 miles is about 100 km. For example, if the post office is a little over a mile away, it is about 2 km away. A town about 60 miles away is about 100 km away.
Fill in the blank with km, m, or cm.
