Lesson 1.1 Integers and Their Opposites

Definitions:

Opposite Integers: An opposite integer is an integer that shares the same distance from 0 as its opposite.
Ex: -1 and 1 or -5 and 5 or -10000000 and 10000000
Absolute Value: The absolute value of a number is the distance that number has from 0. Note: if two numbers share the same absolute value, they will be opposite integers.
Ex: |5| = 5 or |-10| = 10

​Today we are going to learn to identify and use opposite integers. We will do this using number lines, counters and common sense.
