一、在趣味中构建数学问题兴趣能够激发学生的学习热情,数学教学活动要充分调动学生学习的主动性,问题设计就要有趣味性。有趣的数学问题会像一个神奇的魔法棒,引领学生在数学的殿堂里自由翱翔,激发他们浓厚的学习兴趣和求知欲。例如,“认识平行与相交”这节课,我设计了学生尝试画平行线这一环节,并准备了折纸、量角器、直尺等教学工具。提问学生“你能利用这些工具,尝试多种方法画出一组互相平行的线吗?比一比谁的方法多?”孩子们 First, the interest in the construction of mathematical problems in interest to stimulate student enthusiasm for learning, mathematics teaching activities to fully mobilize the initiative of student learning, problem design should be interesting. Interesting math problems like a magical magic stick, leading the students free flight in the math hall, stimulate their strong interest in learning and curiosity. For example, in the lesson “Understanding Parallelism and Intersection,” I designed the students' attempt to draw parallel lines and prepared teaching tools such as origami, protractor, and ruler. Ask students “Can you use these tools to try a variety of ways to draw a set of lines that are parallel to each other? More than one method?” "Children
