Lesson 2: Number line. Negative integers. Comparing numbers

 

Here is a PDF version of the lesson.

Here is a PDF version of the workbook containing lots of practice.

In order to display positive and negative integers in order we often use a number line.

A number line is a line that contains all negative and positive integers, including zero.

When we add and subtract positive and negative integers, we can always use a number line to calculate the absolute distance between the two digits.

For visual learners, a number line is an excellent tool that helps understand operations with integers.

For example, what is -8 + 9?

We would locate the -8 on the number line and move 9 digits in the positive direction (from left to right). We would land on 1, which would be the answer to the problem.

A number line can also be used to compare positive and negative integers.
