Mathematics | Grade : 7

Domain - The Number System

Cluster - Apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers.

[7.NS.A.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.

Resources:


  • Absolute value
    The absolute value of a real number is its (non-negative) distance from 0 on a number line.
  • Additive inverses
    Two numbers whose sum is 0 are additive inverses of one another. Example: 3/4 and –3/4 are additive inverses of one another because 3/4 + (–3/4) = (–3/4) + 3/4 = 0.
  • Rational number
    A number expressible in the form a∕b or – a∕b for some fraction a∕b. The rational numbers include the integers.

Predecessor Standards:

  • 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.
