Short descriptionA complete literal-equations lesson built on one transfer idea: the other letters are constants, and the target variable is the one we're freeing. Students solve formulas (perimeter, area, distance, slope-intercept, and more) for a specified variable using the same legal moves as Lesson 3. Includes a fully scripted new-teacher lesson plan, a Target-Variable Rescue launch, a 15-question homework, a self-checking Mystery Picture, and a quiz. Print PDF + editable PowerPoint + edita
