Now measure each object.

Why is it important that everyone uses the sameunit of measure?

What if your friend measured using a tiny shoe andyou used a giant shoe?

Would your measurement be the same?Is your FOOT the same as your friend’s FOOT?

About 800 years ago, a King of England decided to standardize measurement.

Since most measuring was done using body parts hedecided that everyone should use his FOOT as the

standard unit of measure.So the size of his FOOT is still used today and it is

often called a RULER.

Use the standard FOOT measure to find thelength of each picture.

Why are your measurements the same as others in your class?

The King’s foot was divided into 12 equal unitscalled INCHES.

Use inches to measure each picture.
