“间隔排列”是苏教版小学数学三年级上册第78-79页的教学内容,属于“数与代数”的教学领域,教材以有趣的童话场景为素材,引导学生探索间隔排列中两种物体个数之间的关系以及其中蕴含的简单规律。从三年级开始,苏教版各册教材独立设置“探索规律”的教学内容。学习这样的内容,重在让学生运用已有的数学学习方法和经验,经历由观察现象、探索规律到发现规律,再到完善规律和应用规律,体验学习数学需要运用观察、分析、综合、归纳和抽象、概括等基本数学方法,培养初步的探索意识,积累探
“Permutation ” is the teaching content of the first grade of the Supong version of elementary school mathematics grade three, the first 78-79 pages, belonging to the “number and algebra ” teaching areas, textbooks to interesting fairy tale scenes as material, to guide students to explore the interval arrangement In the relationship between the number of two objects and the simple law contained therein. From the third grade, the textbooks of the Sujiao Editions are set independently for teaching contents of “exploring the law”. Learning to such content, focusing on allowing students to use the existing mathematical learning methods and experience, through the observation of phenomena, to explore the law to discover the law, and then improve the law and application of law, experience learning mathematics need to use observation, analysis, synthesis, induction And abstract, general and other basic mathematical methods to cultivate a preliminary sense of exploration, accumulation of exploration
