Mathematics | Grade : 6

Domain - The Number System

Cluster - Apply and extend previous understandings of numbers to the system of rational numbers.

[6.NS.C.6.a] - Recognize opposite signs of numbers as indicating locations on opposite sides of 0 on the number line; recognize that the opposite of the opposite of a number is the number itself, e.g., –(–3) = 3, and that 0 is its own opposite.

    Predecessor Standards:

    • 3.NF.A.2
      Understand a fraction as a number on the number line; represent fractions on a number line diagram.

    Successor Standards:

    • 7.NS.A.1.a
      Describe situations in which opposite quantities combine to make zero. For example: A hydrogen atom has zero charge because its two constituents are oppositely charged; If you open a new bank account with a deposit of $30 and then withdraw $30, you are left with a $0 balance.
    • 7.NS.A.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.

    Same Level 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, and positive/negative electric charge). Use positive and negative numbers (whole numbers, fractions, and decimals) to represent quantities in real-world contexts, explaining the meaning of zero in each situation.
    • 6.NS.C.7.c
      Understand the absolute value of a rational number as its distance from 0 on the number line; interpret absolute value as magnitude for a positive or negative quantity in a real-world situation. For example, for an account balance of –30 dollars, write |–30| = 30 to describe the size of the debt in dollars.
    • 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 prob-lem. Recognize that inequalities of the form x > c or x < c have infinitely many solutions; represent solutions of such in-equalities on number line diagrams.
