教材是指引教学的主要依据和重要资源,数学是一门具有严密逻辑性的学科,教师对教材应持有科学的质疑态度、深究教学细节,更能打造高效灵动的数学课堂。一、现状点击:“一图”和“两式”的冲突“图式结合”是在“数学图形”与“数量关系”之间建立对应关系并互相转换的教学思想,它在小学数学教学中应用很广泛。苏教版二年级下册“有余数的除法”中有很多“一图两式”练习。(1)根据图形写出不同的除法算式。
Teaching materials refer to the main basis and important resources for guiding teaching. Mathematics is a closely-disciplined subject. Teachers should hold scientific skepticism about teaching materials, go deep into teaching details, and create an efficient and flexible math class. First, the status quo Click: “a map ” and “two-style ” conflict “schema combination ” is in the “mathematical graphics ” and “number relationship ” to establish correspondence and mutual conversion Teaching philosophy, it is widely used in primary school mathematics teaching. Sujiao version of the second grade book “there is a division of the remainder ” there are many “a two-style ” exercise. (1) according to the graph to write different division formula.
