Teach class members to work with rational expressions using their knowledge of fractions. The lesson plan starts with a warm-up of rational expressions at four different levels of complexity. The different levels continue throughout the examples of operations with rational expressions. Finally, learners complete an exit ticket in a collaborative pair.

Instructional Ideas

• Use the different levels of the problems to differentiate the instruction for your class

Classroom Considerations

• The resource assumes the class knows how to factor polynomials
• The collaborative practices include the sage/scribe and the pass-the-pen techniques

Pros

• The resource provides a progression of rational expressions within the examples from simple to complex
• The opening has the class create a table of procedures used with fractions to use with rational expressions

Cons

• Resource includes answers to a worksheet that is not included; you need to create it
