Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in real?world contexts, explaining the meaning of 0 in each situation.

##### 6.NS.C.6

Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous s to represent points on the line and in the plane with negative number coordinates.

##### 6.NS.C.6.A

Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous s to represent points on the line and in the plane with negative number coordinates.

##### 7.NS.A.1.A

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.
