Standards

6.NS.C.5

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.

6.NS.C.7

Understand ordering and absolute value of rational numbers.

6.NS.C.7.A

Understand ordering and absolute value of rational numbers.

7.NS.A.1.B

7.NS.A.2.B

8.NS.A.2

Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., p2).

6.EE.B.8

Write an inequality of the form x > c or x < c to represent a constraint or condition in a real?world or mathematical problem. Recognize that inequalities of the form x > c or x < c have infinitely many solutions; represent solutions of such inequalities on number line diagrams.
