《义务教育数学课程标准》指出:“让学生在生动具体的情境中学习数学。”“学生的数学学习内容应当是现实的、有意义的、富有挑战性的,这些内容要有利于学生主动地进行观察、实验、猜测、验证、推理与交流等数学活动。”这就要求我们一线教师在教学中要创设现实且有吸引力的教学情境,激发学生学习和解决数学问题的兴趣,促使他们用数学的眼光看待现实问题、结合生活实际学习数学,让间接经验的学习有直接的生活经验作支撑,从 The Compulsory Education Math Curriculum Standard states: “Let students learn math in vivid, concrete contexts.” Students’ math learning content should be realistic, meaningful, and challenging, and should benefit from Students take the initiative to observe, experiment, guess, verify, reason and exchange mathematics activities. "This requires our frontline teachers in teaching to create realistic and attractive teaching situations, stimulate students to learn and solve mathematical problems of interest , To promote them to look at the real problems with a mathematical perspective, combined with the actual life of learning mathematics, so that indirect learning experiences have direct experience of life as a support, from
