Increasing student's critical thinking is the focus of many current education discussions. Experts in reading agree that the keys to building critical thinking include: engagement, novelty, cooperative learning, and discussion. Wiggins and McTighe (2005) insist that deep learning and critical thinking can be developed by using questions based on six facets of understanding: explain, interpret, apply, see from various points of view, empathize with various participants, and thinking metacognitively about each subject or element of study. This article describes how these ideas were turned into a card game to not only motivate students to participate but to engage students in critical thinking.
