The social negotiation maintains that the main roles of the environment are to offer alternative views, to develop knowledge, to seek knowledge that is compatible with students' own construction and understanding of the world. It also enhances critical thinking skills such as studying a subject or problem with open- mindedness, determining the facts of a new situation or subject without prejudice, placing these facts and information in a pattern so that students can understand them and accepting or rejecting the source values and conclusions based upon experience, judgment, and beliefs. When students assimilate their current experience with their existing schema, it becomes easier for them to retain learning (Fink, 2003). In this paper, the aim is to show how critical thinking strategies can be used for young learners in reading classes by demonstrating the main steps in the hierarchy of Bloom's taxonomy and applying them to the fairy tales, which lead the learners to show some improvement in their critical thinking strategies.
