In this math video we will learn how to order rational & irrational numbers. We will be given three numerical values - two irrational numbers and one rational number. We will understand that pi is approximately 3.14. We will approximate a non-perfect square, which is irrational, using a number line. We will then order the values from least to greatest and identify the correct answer choice. An exemplar solution is modeled and explained.

00:00 Introduction

The Number System and Expressions and Equations
Know that there are numbers that are not rational, and approximate them by rational numbers.

8.NS.A.2 Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., pi²).

8.NS.A.2 Determine which list orders rational and irrational numbers from least to greatest.
