A horizontal number line marked from -5 to 20. It is marked with major ticks at every 5-unit interval, specifically at -5, 0, 5, 10, 15, and 20, which are labeled accordingly. Minor ticks represent individual units and are placed at each integer between the major ticks. A filled diamond shape indicates the position of

5

on the number line. The position of the number was determined through analysis of the number line, as its exact location was not explicitly provided.

Outcomes

7.NS.1

Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram.

7.NS.1.a

Describe situations in which opposite quantities combine to make 0.

7.NS.1.b

Understand p q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing real-world contexts.

7.NS.1.c

Understand subtraction of rational numbers as adding the additive inverse, p - q = p (-q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.
