活动内容:拼组图形。 活动目的:通过“折·剪·拼”等实践操作活动,使学生进一步认识长方形、正方形、三角形和圆等几何图形,初步了解其特征。培养学生对材料的想象组合能力和创造思维能力。 教材分析: 长方形、正方形、三角形和圆等几何图形,学生已在数学课中初步认识。这节课主要是引导学生把这些图形与日常生活常见的实物图象联系起来,拼成一些生动有趣的图案,从而初步培养学生的创造才能。
Activity: group graphics. Purpose of the Activity: Through the practical operation activities such as “folding, cutting and spelling”, students can further understand the characteristics of rectangular, square, triangle and circle geometry. Develop students' imagination and creative thinking skills. Textbook analysis: rectangles, squares, triangles and circles and other geometry, the students have a preliminary understanding of mathematics. This lesson is mainly to guide students to these images and daily life common physical images linked together into some vivid and interesting patterns, so as to initially cultivate students' creative ability.
