Five integers (3, −4, 0, 5, −2) are placed on a number line with an arrow showing that numbers get greater to the right. The video compares −4 and −2 to show that −2 > −4 even though −4 is further from zero, then reads the line from left to right to give the order −4 < −2 < 0 < 3 < 5.

Transcript

What the lesson says

How do we put these integers in order, from least to greatest?

First, place each number on a number line.

As you move right along the line, the numbers get greater.

Which is greater, negative 4 or negative 2?

Negative 2 is further to the right, so it is greater.

In symbols, negative 2 is greater than negative 4.

Negative 4 is further from zero, but it is less than negative 2.

To put them in order, read the line from left to right.

Negative 4 is furthest left, so it is the least.

Next come negative 2, then 0, then 3.

5 is furthest right, so it is the greatest.

So from least to greatest, the order is negative 4, negative 2, 0, 3 and 5.

The further right a number is on the number line, the greater it is.
