一年级作为起始年级,学生的计算能力至关重要,是以后各年级计算学习的基础,也是学习数学的基础。因而学习20以内的加减法计算是一年级学生的主要任务,那么如何提高一年级学生的计算能力,提高计算的准确率,达到能正确、合理。快速的脱口而出,我就我的教学做法,谈一些浅显的体会。一年级孩子年龄小,没有明确的记忆目标,许多事物是通过无意识记而记住的。他们以机械记忆为主,背诵的本领很高,而意义记识还不大会运用。他们对具体形象的事物记 The first grade as a starting grade, the computing power of students is crucial, is the basis for the calculation of learning in the next grade, but also the basis for learning mathematics. Therefore, learning addition and subtraction within 20 is the primary task of first-year students, then how to improve the computing power of first-year students to improve the accuracy of the calculation, to achieve correct and reasonable. Quickly blurted out, I talk about my teaching practices, some simple experience. First-year children are young, have no clear memory goals, and many things are remembered through the mindless. They are mainly mechanical memory, recite the skills are high, and the sense of meaning is not the general assembly to use. They remember specific things
