Today we worked with finding Least Common Denominators and then creating equivalent fractions. I asked my classes to use factor trees and Venn Diagrams to help with the process. I needed to explain that LCM and LCD are synonymous (they mean the same thing) as both are used to determine the new denominator needed for our equivalent fractions.
We practiced 12 problems as table groups and will continue working with LCD and GCF tomorrow as we begin adding and subtracting fractions and then writing our answer in simplest form.
To see examples from today's activity, please watch the video: Least Common Denominator.
