在小学教材中,计算一直都占有很大的比重。尤其是一至三年级,计算是数学教学中的重要内容之一,因为数学学习几乎都要通过计算来进行,学生计算能力的高低直接影响着学生学习数学的能力,也是学生今后学习数学的重要基础,比如,在解应用题中,解题的步聚和结果都需要计算来落实,再比如,几何知识中的周长、面积、体积等公式的推导与运用也离不开计算。因此,教师应注意对学生计算能力的培养,为学生今后的课程学习打下扎实的基础。下面,笔者结合自己多年的教学实践,对学生数学计算能力的培养略谈浅见。
In primary school textbooks, computing has always accounted for a large proportion. Especially in the first grade to the third grade, computation is one of the most important parts in mathematics teaching. Because mathematics learning is almost always done by calculation, the level of computational ability of students directly affects students’ ability to learn mathematics and is also an important foundation for students to learn math in the future For example, in solving application problems, the steps and the results of solving problems need to be calculated and implemented. For another example, the derivation and application of formulas such as perimeter, area and volume in geometric knowledge can not be done without calculation. Therefore, teachers should pay attention to the cultivation of students ’computing abilities and lay a solid foundation for students’ future course study. Next, I combine my years of teaching practice, the students math ability to raise a little humble opinion.
