新教材最大的特色之一就是:遵循“课标”的理念,注重引导学生“做”数学,引导学生通过“做”数学来感受数学、探索知识和结论、应用所学知识解决简单问题.较多地采用“学生‘做'——在‘做'中感受和体验——主动获取数学知识”的方式呈现,在学生通过“做”获得感受的基础上,揭示具体“事例”的数学本质,然后再明晰有关知识. One of the most prominent features of the new textbook is to follow the notion of class standard and focus on guiding students to do math to guide students through mathematics to explore knowledge and conclusions and apply what they have learned To solve the simple problem of knowledge, we use “student doing” - feeling and experiencing in 'doing' - initiatively acquiring math knowledge ', and based on the students' feeling of being “done” , Reveal the mathematical nature of the specific “case ”, and then clear the knowledge.
