Topic # 4 Investigating Length

Learning Expectations:

* Measure in meters and centimeters

* Make figures with a given perimeter. (distance around)

* Recognize and use connections between distance and time.

Sample Problems:

Remember:

100 centimeters is the same as 1 meter

100 cm = 1m

We can say 150 cm in 3 ways:

150 centimeters

or 1 meter and 50 centimeters

or one and one-half meters

Draw how long you think a centimeter is:

Name something you think is about 1 centimeter. ________________________

Think about a meter stick. Name one thing that is about 1 meter long. ____________________________________________________________________

We can write measurements in more than one way.

150 centimeters is the same as 1 meter and 50 centimeters.

130 centimeters is the same as _____ meter (m) _______ centimeters (cm)

3 meters is the same as ___________ centimeters.

Write the length:

75 centimeters more than 1 meter is _______________ centimeters.

50 centimeters is ____________ centimeters less than 1 meter.

In this topic we talk a lot about 1 mile.

When you are in the car ask your parents to tell you how far a mile is when you are driving. This will help you build a picture in your mind through your own experience.
