### Objectives & Outcomes

Integers are whole numbers but can be whole numbers both greater than or less than zero. Integers are easiest to understand with a number line. Whole numbers that are greater than zero are called natural, or positive numbers.

- Find 10 more or 10 less.

They increase as they move to the right away from the zero. Negative numbers are below or to the right of the zero. Number names grow bigger with a minus for "negative" in front of them as they move away from the zero to the right.

Numbers growing larger, move to the left. Numbers growing smaller as in subtraction move to the right.
