AP Calculus Error Analysis & Find-the-Mistake Practice — Zero Hour: Error Audit
"Check your work" is a useless instruction unless students know what they're looking for. Error Audit teaches them to look — by giving them other students' work to dissect. Every problem in this skill set presents a worked solution with one or more embedded errors. Students don't redo the problem; they audit it. They identify the error, name the type (algebraic slip, conceptual misread, notation failure, sign error, derivative-of-a-product mistake, chain rule omission, etc.), and write the corre
