Oliver draws a sign in the dirt with a stick.
"This sign is like a hungry mouth," he says.
"The open side always faces the greater number."
Bennie writes 356 and 382.
"Both have 3 hundreds," says Bennie.
"So now we look at the tens!"
Learn it: the signs
The sign > means greater than.
The sign < means less than.
The sign = means equal to.
In 356 and 382, the hundreds are the same.
5 tens is less than 8 tens.
So 356 < 382.
On a number line, the greater number is farther to the right.
