# Arranging Integers in Order

An important skill is to be able to place positive and negative “integer” whole numbers into ascending and descending order.

Comparing Integers

A Number Line is very useful for working with directed number Integers.

On a number line, NUMBERS TO THE RIGHT ARE BIGGER.

NUMBERS TO THE LEFT ARE LESS THAN ones to the right.

For example: 6 is bigger than 3, but -6 is smaller than 3.

We say that 6 is greater than 3, and we write this as 6 > 3

However, -6 is less than 3, and we write this as -6 < 3

Using Inequality Signs

> means greater than, or bigger than

< means less than, or smaller than. ( less than points to the left )

For the “inequality signs” < and >

THE POINTY ARROW ALWAYS POINTS TO THE SMALLER NUMBER.

Eg. 2 < 4, 8 > 5, -4 < -1, -2 > -6

The Fish Rule

Some people also like to think of the arrow sign as looking like the mouth of a fish.

They then use the following rule:

“The hungry Fish always wants to eat the bigger amount”.

So the open “<” mouth of the fish always goes towards the bigger item.

Placing Inequality Signs Rules

If the first number is more to the right, put a > sign.

If the first number is more to the left, put a < sign.

This will ensure that the arrow always points to the smaller number.

Remember to use a number line, ( especially for negative numbers ), and that :

NUMBERS TO THE RIGHT ARE BIGGER.

NUMBERS TO THE LEFT ARE SMALLER.

THE POINTY ARROW ALWAYS POINTS TO THE SMALLER NUMBER.

Represent Order and Compare Integers

The following is a video about comparing Integers, eg. Greater Than and Less Than, and placing Integers into ascending order.

It has no soundtrack, but has good slides.

The one limitation is that we cannot go full screen.

Using a Number Line to Order Integers

The following video from “School Tube” gives two examples of plotting Integers onto a Number Line.

We can then write the Integers out from left to right, which gives us their order from lowest to highest.

Ordering Integers Game

In the following game, use the mouse to place the three red integer numbers in order, onto the carriages and the train engine.

The biggest number always goes onto the steam engine.

It is very important to place the numbers exactly in the middle of the carriages and engine like this:

If your answer is correct, the train should move to the right and off the screen.

Note that you will probably have to page down the screen a bit to get to the actual game.
