Slide presentation showing how to create equivalent fractions For the fraction 2/3, the number equal parts is initially 3. After one cut, there are two times as many equal parts. The red box represents 4/6 of the whole. After two cuts, there are three times as many of equal parts. The red box represents 6/9 of the whole. After three cuts, there are four times as many equal parts. The red box represents 8/12 of the whole. Have students predict what will happen after four cuts, five cuts and so on. Then have them use that information to generate a process for finding equivalent fractions using only numbers. J Squared MCR LLC

Equivalent fractions: Area Model Consider the fraction The area inside in the red box (2/3 of the whole) is still the same area. It has been divided into more equal parts. J Squared MCR LLC

Equivalent fractions: Area model Consider the fraction The area inside in the red box (3/4 of the whole) is still the same area. It has been divided into more equal parts. J Squared MCR LLC

Equivalent fractions: Area Model Consider the fraction The area inside of the red box (1/5 of the whole) is still the same. It has been divided into more equal parts. J Squared MCR LLC
