Content Standard MAFS.6.NS The Number System MAFS.6.NS.3 Apply and extend previous understandings of numbers to the system of rational numbers. MAFS.6.NS.3.5 Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation.

Assessment Limits Numbers in items must be rational numbers. Items should not require the student to perform an operation.

Content Standard MAFS.6.NS The Number System MAFS.6.NS.3 Apply and extend previous understandings of numbers to the system of rational numbers.

o MAFS.6.NS.3.6a Recognize opposite signs of numbers as indicating locations on opposite sides of 0 on the number line; recognize that the opposite of the opposite of a number is the number itself, e.g., −(−3) = 3, and that 0 is its own opposite.

o MAFS.6.NS.3.6b Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes.

MAFS.6.NS.3.6c Find and position integers and other rational numbers on a horizontal or vertical number line diagram; find and position pairs of integers and other rational numbers on a coordinate plane. Also Assesses:

MAFS.6.NS.3.8 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 first coordinate or the same second coordinate.

Assessment Limits Numbers in items must be rational numbers. Plotting of points in the coordinate plane should include some negative values (not

just first quadrant). Numbers in MAFS.6.NS.3.8 must be positive or negative rational numbers. Do not use polygons/vertices for MAFS.6.NS.3.8. Do not exceed a 10 × 10 coordinate grid, though scales can vary.

Content Standard MAFS.6.NS The Number System MAFS.6.NS.3 Apply and extend previous understandings of numbers to the system of rational numbers.

o MAFS.6.NS.3.7a Interpret statements of inequality as statements about the relative position of two numbers on a number line diagram. For example, interpret −3 > −7 as a statement that −3 is located to the right of −7 on a number line oriented from left to right.

MAFS.6.NS.3.7b Write, interpret, and explain statements of order for rational numbers in real-world contexts. For example, write −3 oC > −7 oC to express the fact that −3 oC is warmer than −7 oC.

MAFS.6.NS.3.7c 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 situation. For example, for an account balance of −30 dollars, write | − 30| = 30 to describe the size of the debt in dollars.

MAFS.6.NS.3.7d 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.
