“When learning materials and students have only been associated with experience to stimulate students interest in learning and solving problems, mathematics is living, full of vitality.” Learning is the student’s initiative to construct activities for students Rich and interesting learning materials to create an open and effective learning environment so that the new knowledge gained is not only easy to maintain but also conducive to migrating to new situations and attracting them to actively participate in math activities and to experience, feel and discover , Through the process of mathematical learning. 1 Let the material “living ” up, the student “move ” Up Teaching scenario creation, learning content presentation, not only to pay attention to fun, intuitive, pay attention to the combination of image thinking and abstract thinking, but also need to focus on contact with students of
