Unit 3, Lesson 1# Positive and Negative Numbers on the Number Line--Opposite Direction and Value

EngageNY 45 min(s)

Students extend their understanding of the number line, which includes zero and numbers to the right or above zero that are greater than zero and numbers to the left or below zero that are less than zero. Students use positive integers to locate negative integers by moving in the opposite direction from zero. Students understand that the set of integers includes the set of positive whole numbers and their opposites, as well as zero. On a horizontal number line, do the numbers increase or decrease as you move farther to the right of zero?
