Recommended Additional Lesson(s): Students will recognize that two rational numbers that lie on the same side of zero will have the same sign, while those that lie on opposites sides of zero will have opposite signs. Additional Information: Task(s): Number lines can be used to show numbers and their opposites. Both 3 and -3 are 3 units from zero on the number line.
