- 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.

Irrational Numbers

Worksheet, Formative Assessment, and Activities from orgLib.comThese worksheets can be used in multiple modes. See this page for how it works: http://www.orglib.com/howitworks_s.htmlSupports the following Standards of Mathematical Practice• 2 Reason abstractly and quantitatively.• 5 Use appropriate tools strategically.• 6 Attend to precision.• 7 Look for and make use of structure.• 8 Look for and express regularity in repeated reasoning.

8.NS: This lesson unit is intended to help you assess how well students are able to distinguish between rational and irrational numbers. In particular, it aims to help you identify and assist students who have difficulties in: • Classifying numbers as rational or irrational. • Moving between different representations of rational and irrational numbers. Supports the following Standards of Mathematical Practice • 2 Reason abstractly and quantitatively. • 7 Look for and make use of structure. • 8 Look for and express regularity in repeated reasoning.

8.NS: This lesson unit is intended to help you assess how well students reason about the properties of rational and irrational numbers. In particular, this unit aims to help you identify and assist students who have difficulties in: • Finding irrational and rational numbers to exemplify general statements. • Reasoning with properties of rational and irrational numbers. Supports the following Standards of Mathematical Practice • 2 Reason abstractly and quantitatively. • 7 Look for and make use of structure. • 8 Look for and express regularity in repeated reasoning.
