- 8.NS.1 - Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number.
- Understand and apply the definition of rational numbers
- Understand and apply the definition of irrational numbers
- Distinguish between rational and irrational numbers
- Compare irrational and rational number
