This activity is about ordering positive and negative numbers.
Think of a number line.
As you move to the left of a horizontal number line, the numbers get smaller.
Remember that:
< means "is smaller than"
> means "is bigger than"
So...
5 > -10
-53 < 53
-53 < -50
The further to the left of zero we get on a number line, the smaller the number.
Think about the reading on a thermometer on a really cold winter's day! If the temperature outside is -3, it's pretty cold, but if it goes down to -10, then it is even colder! -10 is colder than -3 because it is further away from zero.
Example 1
