dc.description.LearningOutcomeStudents recognize that the rules for adding and subtracting integers apply to rational numbers. - Given a number line, students use arrows to model rational numbers where the length of the arrow is the absolute value of the rational number and the sign of the rational number is determined by the direction of the arrow with respect to the number line. - Students locate the sum 𝑝𝑝+𝑞𝑞 of two rational numbers on a number line by placing the tail of the arrow for 𝑞𝑞 at 𝑝𝑝 and locating 𝑝+𝑞 at the head of the arrow. They create an arrow for the difference 𝑝−𝑞 by first rewriting the difference as a sum, 𝑝+(−𝑞), and then locating the sum.
