翻开新课改的数学实验教材,就像在看一本本故事画册。教材密切联系学生生活,构成情景串,引发出一系列的问题,形成问题串,将整个单元的内容串联在一起,使学生在解决一连串的现实的、有挑战性问题的过程中,融入数学课程。这极大调动了学生的学习兴趣,同时也让学生深刻地感受到数学与生活的联系。实践中,我发 Open the new course of mathematics experimental textbooks, like watching a story book. Textbooks closely relate to student life, form a series of scenarios, trigger a series of questions, form a series of questions, concatenate the contents of the entire unit, and enable students to incorporate mathematics lessons in solving a series of realistic and challenging questions . This greatly mobilized students’ interest in learning, but also allow students to deeply feel the connection between mathematics and life. In practice, I send
