Creating Equivalent Fractions

Updated on 07/24/2015

Activity Overview

This activity is intended to be a deeper investigation into equivalent fractions, going beyond recognizing and identifying them.  Students should know that two numbers are equivalent (equal) if they are located at the same point on the number line and that the larger of two numbers is the one farther to the right on the number line.

About the Lesson

This TI-Nspire  lesson is intended to be a deeper investigation into equivalent fractions, going beyond recognizing and identifying them as students did in the earlier activity Equivalent Fractions. Students should know that two numbers are equivalent (equal) if they are located at the same point on the number line and that the larger of two numbers is the one farther to the right on the number line. To create equivalent fractions with a larger numerator and denominator students multiply both by a number greater than 1. To create an equivalent fraction with a smaller numerator and denominator (i.e., reducing a fraction) students divide both by a nonzero number that is a common factor of both the numerator and denominator.

This is Lesson 4 out of 15 in the Building Concepts in Mathematics: Fractions Series.
