- add unit fractions with different denominators,
- add proper fractions with different denominators whose sum is at most one,
- add proper fractions with different denominators whose sum is greater than one.
Prerequisites
Students should already be familiar with
- finding common denominators of fractions using multiplication and division up to .
Exclusions
Students will not cover
- finding least common multiples using prime factors.
