What is Measurement?

Measurement is finding a number that shows the size or amount of something.

Measuring how long things are, how tall they are, or how far apart they might be are all examples of length measurement.

Inches and FeetAn inch is about the width of a large

thumb.

A foot is about the length of a large foot.

What Have We Learned?Let’s Review

12 inches = 1 foot

Lots of things are measured in inches; from rainfall to paper

length.

An inch is about the size of the tip of your thumb to the first knuckle.

A foot is about the size of the tip of your finger to your elbow.

What Have We Learned?Let’s Review

100 centimeters = 1 meter

Meters might be used to measure the length of a house, or the size of a

playground.

A centimeter is about the width of your pinky finger.

A meter is about the distance from finger tip to finger tip.

Uh-Oh!

Let’s measure that one more time!

Whoops!

I don’t think we measured far enough.

LET’S TRY AGAIN!
