- Quiz - 8.NS The Number System Cluster: Know that there are numbers that are not rational, and approximate them by rational numbers. Standards: 8.NS.1, 8.NS.2
- 8.NS.1 Know that numbers that are not rational are called irrational.
- 8.NS.2 Use rational approximations of irrational numbers to compare the size of irrational numbers.

FHSST is a project that aims to provide free science and mathematics textbooks for Grades 10 to 12 science learners. The project was initiated by young South African scientists, and now brings together scientists from around the world who are willing to contribute to the writing of the books. Below is a complete Table of Contents for this chapter. This resource is part of the FHSST Mathematics collection.
