Middle/high school: 3 lesson plans that can be used separately or together as a unit--complete with two hand-outs (Factoring Polynomials & Rational Expressions and Equations) that link together the concepts of fractions, polynomials, and rational expressions/equations.
Aligned with common core standards.
Timed for 60 minute periods, but can be adjusted for block and other schedules.
Hand-outs are a great resource in themselves, and can be copied and given to students as a reminder for identifying polynomial patterns and performing operations on rational expressions and solving rational equations.
Comprehensive unit--can be divided into more than 3 lesson plans, as needed. Can be shortened if students are not yet working with rational expressions or equations.
