This Instructional Activity is a part of the Lesson 4, Unit 7, Grade 6. In this activity, students order rational numbers from least to greatest in 2 steps. They first order positive rational numbers, and then negative ones. The numbers are written as fractions, decimals, and integers. By manipulating physical cards, students get a tangible sense of how rational numbers relate to each other. Notice conversations students have when deciding how to place fractions and decimals, especially on the negative side of the number line.
