6th Grade Math Guide

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 context. For example: for an account balance of – 30 dollars, write | – 30| = 30 to describe the size of the debt in dollars. d. Distinguish comparisons of absolute value from statements about order. For example: Recognize that an account balance less than – 30 dollars represents a debt greater than 30 dollars. Standard 6.NS.8 Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same x coordinate or the same y-coordinate.

Skill Building

From Activity 8.2: MLR 7 Compare and Connect. To foster students’ meta awareness of language as they compare and contrast different mathematical situations, display these two sentences: “A fishing boat can hold fewer than 9 people” and “A magician will perform her magic tricks only if there are at le ast 9 people in the audience.” Ask students what is the same and what is different about these two situations. Invite students to work with a partner to find values can be true for each statement. This discussion makes explicit the language of inequalities (e.g., fewer, at least), and offers an opportunity to connect verbal descriptions to solution sets of numbers. From Lesson 13 “Are You Ready for More?”: The point (0, 4) is 5 taxicab units away from (-4, 3) and 5 taxicab units away from (2, 1). 1. Find as many other points as you can that are 4 taxicab units away from both (-4, 3) and (2, 1). 2. Are there any points that are 3 taxicab units away from both points?
