小学数学教材是根据教学大纲规定的小学数学教学目的要求而编写的材料。它既注意到数学学科的特点,又注意到儿童的认知规律,建立合理的知识结构。教材是教师教学的依据,也是小学生学习数学知识的一个重要来源,是发展学生数学能力的基础。教师只有认真研究教材,理解编者的意图,掌握教材的来龙去脉,驾驭教材,教学中才能较好地发挥其应有的知识和智力价值,落实教学目的,达到教学要求。研究教材就要努力熟悉小学各年级的教学内容, Primary mathematics textbooks are based on the syllabus of primary mathematics teaching objectives and requirements of the preparation of the material. It not only noticed the characteristics of mathematics, but also noticed the children's cognitive rules and established a reasonable knowledge structure. Teaching materials are the basis for teachers' teaching and are also an important source of primary school students' knowledge of mathematics. They are also the basis for developing students' mathematical abilities. Only when teachers carefully study teaching materials, understand the intent of editors, grasp the ins and outs of teaching materials, master the teaching materials, can they exert their due knowledge and intellectual value well, fulfill their teaching aims and meet the teaching requirements.
