A fraction chain helps students build a whole by using units. For example, a basic fraction chain is 1/3 +1/3 +1/3= 3/3 = 1 whole. Activities with fraction chains are useful to help students understand non-unit fractions are made by putting together unit fractions. Fraction chains are also useful to help identify fractions and help with fraction addition errors. Fraction chains are also useful with fraction subtraction. They make it easier for students to visualize the process. Grasping the concept of a fraction chain will lead to students being able to understand more complex fractions.
