Use different units to measure the same object.

Measuring lengths with different units

Let's measure a fence with squirrels!
The fence is 10 squirrels long.
Now let's measure the same fence with ponies.
The fence is 5 ponies long.
Why did it take fewer ponies to measure the length of the fence?

The ponies are longer than the squirrels.
Because the ponies are longer, it will take fewer ponies to measure the length of the fence.

Practice problem 1

This is a rectangle.
Let's measure the start color blueD, b, l, u, e, space, l, i, n, e, end color blueD below using both rectangles and a centimeter ruler:
The line is
rectangles long.

The line is
centimeters long.

The line is 12 rectangles long.
The line is 6 centimeters long.
The width of each rectangle is _____ than a centimeter.

So, it takes _____ rectangles than centimeters to measure the line.

The width of each rectangle is shorter than a centimeter.
So, it takes more rectangles than centimeters to measure the line.

Practice problem 2

Measure the start color greenD, g, r, e, e, n, space, l, i, n, e, end color greenD using the centimeter ruler.
The line is
centimeters long.

Now, measure the start color greenD, g, r, e, e, n, space, l, i, n, e, end color greenD using the inch ruler.
The line is
inches long.

It takes _____ centimeters than inches to measure the line.

So, a centimeter is _____ than an inch.
