3.1 Number Lines, Additive Inverses, & Absolute Values

Learning Target:

• I can determine the absolute value and additive inverse of a rational number.
• I can model, compare, and evaluate integers.

CCSS:

• 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.
