# MATH

• WELCOME TO MATH!

Yesterday we learned about Meters, and today we will learn about a metric unit of measure called a kilometer.
A kilometer (km) is used to measure long distances.
You are accustomed to the U.S. standard of measure for long distances called the mile.
The kilometer (km) is used similarly in many countries other than the United States.
A kilometer (km) is about how far you can walk in 15 minutes.

There are 1000 meters in one kilometer.

Please take a look at Problems numbered 1 - 6 on page 274.
When you feel confident that you have answered them correctly, please compare your answers to the ones I've written below. They should match.

1. cm
2. km
3. m
4. cm
5. km
6. m

Now we can have some fun with the diagram (map) on page 275.
You are welcome to use a ruler with cm markings to help understand the diagram, but it is not necessary to use a ruler to answer the questions.

Please notice that this diagram is actually a map, and according to the scale they have given you, every centimeter (cm) on the diagram is equal to one kilometer (km) of real distance between locations on the map.

First, answer the questions on your own, and then check them against the answers I am presenting below to be sure they match.

15. 3 km is less than 5 km; shorter
16. 3 km
17. 5 km + 4 km = 9 km; about 9 km
18. 5 cm
19. 4 km
20. 5 km + 5 km = 10 km; 10 km
21. through Pinecrest;
4 km + 5 km = 9 km; 9 km

Terrific!
