Lesson Plan: Adding Fractions with Unlike Denominators Mathematics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to add two proper fractions with different denominators by finding a common denominator.
Objectives
Students will be able to
- represent addition of fractions using models including bar models,
- 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.
