To give students greater independence, there is an answer key for the practice problems of every lesson. I know what a lot of teachers are thinking at this point: what if the student just copy all their answers from the answer key? As an Algebra teacher told me when I asked them the same question before starting flipped mastery, they'll just fail the mastery quiz. It only takes a few correctional assignments for them to realize that the answer key is there to check answers, not copy them.

Correctional Assignments provide another layer of practice for my students who fail a quiz before re-attempting to master the topic. The process is simple - my students complete the Correctional Assignment and then re-take the mastery quiz. My students can follow this process as many times as needed until they pass the quiz and achieve mastery. For this reason, I use IXL.com and Kuta Software for Correctional Assignments, which both generate infinite sets of practice problems.
At the beginning of each trimester students are given a checklist to track their own mastery. As they progress through the lessons, they mark off what they have completed, in addition to the grade they received on each lesson. This acts as planner, letting students know at any given moment what they have completed, and what is left for them to learn to finish the trimester.
