### Intentionality…

- Situations involving addition and subtraction can be modelled using a number line;
- Integers include zero, all whole numbers and their opposites;
- Integers represented on a number line show their relative distance from zero;
- Some addition and subtraction scenarios follow the structure of start, change and result;
- An integer can represent a change or a quantity;
- When a positive and a negative integer are added together, the result is positive if the absolute value of the positive integer is greater than the absolute value of the negative integer;
- Two integers can be represented as positions on a number line to determine the distance between them (magnitude);
- The order in which a subtraction statement is written is important.

- I will represent positive and negative integers.
- I will describe contexts involving positive and negative integers.
- I will add integers.
- I will subtract integers.
- I will use a model to represent the addition and subtraction of positive and negative integers.
- I will demonstrate an understanding of the behaviour of addition and subtraction.
