# 7. Add Fractions (Sums up to 1)

Practice adding like fractions (fractions with same denominators). Adding fractions is like adding different parts of a whole. In **Add Fractions (Sums up to 1) Worksheet**, students use visual representations (area models and number lines and fraction strips) to model addition of fractions and add like fractions with sums within 1.
