# 1. Add Fractions

In the previous grade, students add fractions with like denominators. In **Add Fractions Worksheet**, they add two fractions with unlike denominators. They do so by using their previous knowledge of equivalence of fractions to replace the fractions by those with like denominators. For example, 2/3 + 1/6 = 4/6 + 1/6 = 5/6.
