近几年来有关规律探索性题目在中考数学中频繁出现,成为中考数学选择题、填空题和压轴题必考题型之一.新课标指出:“创新意识的培养是现代教育的基本任务,归纳概括得到猜想和规律并加以验证,是创新的重要方法,创新意识培养应该贯穿数学教育始终.”因此这类题目不仅要求学生学会观察、懂的分析、善于归纳,更重要的是提高学生的思考问 In recent years, the exploration of the law of the topics frequently appear in the mathematics in the test, a choice of the math test, fill in the blank questions and finale questions one of the exam questions.New curricula pointed out: “The cultivation of innovative awareness is the basic task of modern education, To summarize and verify the conjecture and law is an important method of innovation, and training of innovative consciousness should be carried out throughout mathematics education. ”Therefore, such topics not only require students to learn observation and understand analysis, but also to improve students’ Ask
