培养动手操作和探究能力是素质教育所 要求的重要内容之一．亲自参与活动进行探 索与发现,以自己的体验获取知识与技能是 数学教学的重要目标．“循环分割”图形的操 作探究题是在操作、观察、猜想、归纳的基础 上探究出这种“循环分割”的规律,使感性认 识升华为理性认识,从而培养数学素养和创 新能力． Training hands-on operation and inquiry ability is one of the important contents of quality education. It is an important goal of mathematics teaching to personally participate in activities for exploration and discovery, and to acquire knowledge and skills with your own experience. The operation inquiry question of the “circular segmentation” graph is to explore the law of “circular segmentation” on the basis of operation, observation, conjecture and induction, so that perceptual knowledge is sublimated into rational knowledge, thereby cultivating mathematical literacy and innovation capabilities.
