“综合与实践”活动是学生积累数学活动经验的重要载体,对培养学生创新思想、批判性思维、解决问题能力和终身学习能力等的全面发展具有重要和深远的意义。以小学数学“图形与几何”知识为载体,以学生自主参与、综合运用“图形与几何”的知识和方法解决实际问题为研究内容,让学生在自主探究中提高综合实践能力,培养数学核心素养和21世纪技能,发展学生空间观念。 Comprehensive and Practical Activities is an important carrier for students to accumulate experiences in mathematical activities and has important and far-reaching significance for the all-round development of students’ innovative thinking, critical thinking, problem-solving skills and lifelong learning ability. Based on the knowledge of elementary mathematics “Graphics and Geometry ” as the carrier, students take part in their own activities and make comprehensive use of the knowledge and methods of “Graphics and Geometry ” to solve practical problems as the research content and enable students to improve their comprehensive practical ability in self- Cultivate the core competence of mathematics and 21st century skills and develop the concept of student space.
