DESCRIPTION:

Discovery Education Video. Video discusses irrational numbers such as the number pi because it has no decimal equivalent. Then it discusses how irrational numbers relate to rational numbers. Video is good quality and good for all students as a review or initial learning of the topic.

OVERVIEW:

Relevance: Use of Irrational Numbers is a free educational video by laneCrease.It helps students in grades 8 practice the following standards 8.NS.1,8.NS.A.1,8.NS.2.

This page not only allows students and teachers view Relevance: Use of Irrational Numbers but also find engaging Sample Questions, Apps, Pins, Worksheets, Books related to the following topics.

1. 8.NS.A.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..

2. 8.NS.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., ?^2). For example, by truncating the decimal expansion of ?2 (square root of 2), show that ?2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations..
