- Lesson Plan →Objectives, pacing and practice, built from this lesson's brief.
- Guided Notes →One page your students fill in and keep.
- Exit Ticket →Three items at the end of class. No student accounts.
- Re-teach →After an exit ticket: who missed what, and what to do tomorrow.
- Homework →Assign practice; it grades itself.

What you'll learn
- Solve a rational equation by listing its excluded values, clearing denominators (by the LCD, or by cross-multiplication when the equation is one fraction equal to one fraction), and rejecting any candidate that is an excluded value
- Explain why clearing denominators can produce an extraneous solution
- Solve a rational equation whose cleared form is quadratic, reporting the solution set correctly when a root is rejected
- Set up and solve a work-rate problem that produces a rational equation
