This Instructional Activity is a part of the Lesson 2, Unit 7, Grade 6. The purpose of this task is both to build an understanding of the symmetry across zero on the number line and to start introducing the notion that we can compare the distance from zero, or the absolute value, of numbers. Though this activity does not explicitly introduce the vocabulary of absolute value, it seeds the idea that a positive and a negative number can each have the same absolute value. This is also the first time students work with negative numbers on a horizontal number line.
