The Math Practice to Mastery! program utilizes the "Most Difficult First" method, where students who already have the skill mastered can become tutor leaders in your class and not have to do the repetitive practice that most learners need. This unique method gives students who need the repetition the opportunity for enough practice to master the skills. It's a Win-Win!
