Directed measurement --- a rational number’s position on the number line is found using length and direction. The opposite of a number a, is –a. Both a and –a are located an equal distance from zero, in opposite directions. Rational numbers represent real-world situations.

© 2012 Common Core, Inc. All rights reserved. commoncore.org NYS COMMON CORE MATHEMATICS CURRICULUM A Story of Ratios Positive and Negative Numbers on the Number Line: Opposite Direction and Value Lesson 1 Outcomes: Students extend their understanding of the number line, which includes zero and numbers to the right, that are above zero, and numbers to the left, that are below zero. Students use positive integers to locate negative integers, moving in the opposite direction from zero. Students understand that the set of integers is the set of whole numbers and their opposites, and understand that zero is its own opposite.

© 2012 Common Core, Inc. All rights reserved. commoncore.org NYS COMMON CORE MATHEMATICS CURRICULUM A Story of Ratios Positive and Negative Numbers on the Number Line: Opposite Direction and Value The number line extends to include negative numbers. Lengths on the right-side and left-side of zero are the same for a number and its opposite. (Use a compass for the construction.) The set of whole numbers and their opposites (zero is its own opposite) are called integers. The order of the set of integers is: …-5,-4,-3,-2,-1,0,1,2,3,4,5… Lesson 1

All rights reserved. commoncore.org NYS COMMON CORE MATHEMATICS CURRICULUM A Story of Ratios Positive and Negative Numbers on the Number Line: Opposite Direction and Value Lesson 1/Activity Draw a horizontal line. Place a point on the line and label it 0. Use a compass to locate and label the next point 1, thus creating a scale. (Continue to locate other whole numbers to the right of zero using the same unit measure.) Using the same process, locate the opposite of each number on the left side of zero. Label the first point to the left of zero, -1.

All rights reserved. commoncore.org NYS COMMON CORE MATHEMATICS CURRICULUM A Story of Ratios Ordering Integers and Other Rational Numbers Lesson 7 Outcomes: Students write, interpret, and explain statements of order for rational numbers in real world contexts. Students recognize that if a -b, because a number and its opposite are equal distances from zero; and moving along the horizontal number line to the right means the numbers are increasing.

All rights reserved. commoncore.org NYS COMMON CORE MATHEMATICS CURRICULUM A Story of Ratios Key Points Directed measurement --- a rational number’s position on the number line is found using length and direction. The opposite of a number a, is –a. Both a and –a are located an equal distance from zero, in opposite directions. Rational numbers represent real-world situations. We can write and explain statements of order for rational numbers in real-world contexts. The absolute value of a number is its distance from zero; and can be used in the context of a situation to show magnitude. We can use absolute value and the symmetry of the coordinate plane to solve problems related to distance.
