【摘  要】在当前的小学中低年级计算教学活动中，依然存在一些问题，教师过度关注学生计算的速度与准确性，习惯用“讲清算法，强化训练”的教育模式，这样虽然能让学生掌握计算技巧、计算方法，但是会让学生丧失参与计算活动的主观能动性。由此，教师一定要注重计算教学模式的优化、改革，结合小学生真实的计算能力、学习需求，科学设定计算教学方案，以此提高计算教学活动的有效性，全面落实素质教育理念。本文主要对如何提高小学中低年级计算教学有效性展开探析，希望为提升小学生计算能力提供借鉴和参考。

Ways to Improve the Effectiveness of Calculation Teaching in Middle and Lower Grades of Primary Schools

（Experimental Primary School of  Yong'an City， Fujian Province，China） XU Huizhen

【Abstract】There are still some problems in the current calculation teaching activities in the middle and lower grades of primary schools. Teachers pay too much attention to the speed and accuracy of students' calculations and are used to the educational model of "clarify the algorithm and strengthen training". Although this allows students to master calculation skills and calculation methods， it will make students lose their initiative to participate in calculation activities. Therefore， teachers must pay attention to the optimization and reform of the calculation teaching model， combining the real calculation ability and learning needs of primary school students， and scientifically set the calculation teaching plan to improve the effectiveness of calculation teaching activities and fully implement the concept of quality education. This article mainly explores how to improve the effectiveness of calculation teaching in the middle and lower grades of primary school， hoping to provide reference for improving the calculation ability of primary school students.

素质教育理念的引领下，在小学中低年级计算教学活动中，教师要注重培養学生数学学科核心素养，从中锻炼学生的计算能力、思维能力、实践能力、创新能力，让学生在计算中归纳、总结，强化学生的学习体验、情感体验，激发学生的数学学习兴趣，养成良好的学习态度。同时，在小学中低年级计算教学活动中，教师要把算法与算理作为核心内容，明确用算、会算的核心要求，设定“四能”“四基”的核心目标，科学设定计算教学方案，强化计算教学活动的导向性，以此提升学生的计算能力、计算准确性，引导学生从中真正有所收获、提升、学习，提高小学中低年级计算教学活动的有效性。

一、创设情境，激发学生学习的积极性
