Give students the tools and the experience they need to critically analyze text and respond to test questions that are correlated to Common Core Standards. Begin with Test A which provides call-out tips on how to approach each question or problem. Progress to Test B which provides fewer tips. Test C provides no tips. Since the goal is to learn to think critically (not just score well), the answer key gives not just the right answers, but also explanations for why one answer is correct and the others are incorrect.
