# MATH

• WELCOME TO MATH!

Previously we learned about inches, feet, and yards, which are units of measurement used in the U.S.

Today we will continue our study of the metric system (units of measurement used in other countries), specifically the unit of Meters.

Meters are a metric unit used to measure long lengths.

Your textbook states that a door can be used as a good example of something which measures about one meter wide.

►There are 100 centimeters (cm) in one meter.

►You recall that 10 cm = 1 dm (decimeter). If we divide a meterstick into groups of 10 cm each, we woud have 10 markings on the meterstick.
Each marking would show us one decimeter.
There are 10 dm in one meter.

Here is a video from Discovery Education which further explains the metric unit of Meters.

• Let's look at some of the problems on page 272 of your Math textbook.
