【设计内容】《认识角》是小学《数学》苏教版义务教育课程标准实验教科书第四册P73—76“认识图形”的第一课时,主要是让学生了解有关角的知识。本设计通过“拼一拼”、“摸一摸”等一系列的体验性活动贯穿全课。【设计理念】新课标指出,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。从教学内容看角的认识并不是纯粹的知识性学习,而是一种体验性的活动,包含了丰富的过程性的学习目标。所 Design Content “Recognition Corner” is the primary school “Mathematics” Supian version of Compulsory Education Curriculum Standard Experimental Textbook Volume IV P73-76 “understanding graphics ” the first class, mainly to enable students to understand the knowledge about the angle. The design through the “fight a fight ”, “touch ” and a series of experiential activities throughout the class. [Design Concept] The new curriculum standard pointed out that students should be realistic, meaningful and challenging mathematical learning content. Understanding from the perspective of teaching content is not a purely knowledge-based learning, but an experiential activity that contains a wealth of procedural learning objectives. The
