3 STANDARDS THE NUMBER SYSTEM TEACHER GUIDE 6.NS.5 Understand that positive and negative numbers are used together to describe quantites having opposite directions or values; use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation. 6.NS.6. Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with negative number coordinates. a. 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, and that 0 is its own opposite. b. 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. c. 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. 6.NS.7. Understand ordering and absolute value of rational numbers. a. Interpret statements of inequality as statements about the relative position of two numbers on a number line diagram. b. Write, interpret, and explain statements of order for rational numbers in real world contexts. 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 situation. d. Distinguish comparisons of absolute value from statements about order. VOCABULARY & KEYWORDS absolute value: integer: magnitude: opposite: rational number: the distance a number is away from zero a positive or negative whole number the distance a number is away from zero; typically used in a problem situation two integers can be opposites if they are equal distance away from zero on the number line but on different sides of zero a number that can be written as a fraction, as a terminating decimal or as a repeating decimal whole number: a positive counting number starting with 0 COMMON MISTAKES & MISCONCEPTIONS Students may order numbers the wrong way, ex: least to greatest rather than greatest to least. Students may struggle to place rational numbers on the number line in the correct position.

8 THE NUMBER SYSTEM STATIONS INSTRUCTIONS TO PREP Print station cards on cardstock and set up desks into groups of 3-4. Print and copy a recording sheet for each student. TO USE Students should work through all stations, showing their work and solutions on their recording sheet. OTHER TIPS Laminate station cards to protect the cards for future use. This activity works well when students are in groups of 3-4.
