在小学数学的混合运算中,是学生已经基本掌握了整数的四则运算的学习基础上进行的。混合运算是根据已有的整数四则运算的学习基础上进行连加、连减、加减混合以及连乘、连除、乘除混合等的同级的两步运算,但运算顺序都是从左往右进行计算的,往往会使学生进入思维定势。为了打破学生的思维定势,便需要老师在教学中由浅入深的促使学生掌握混合运算的顺序。根据以上存在的教学问题,浅谈小学数学混合运算的教学方法。
In elementary mathematics, mixed arithmetic is based on the students’ basic mastery of the arithmetic of the four arithmetic operations. Mixed operation is based on the existing integer four operations on the basis of the learning, adding, subtracting, adding and subtracting mixed and even multiply, even with the addition and subtraction mixed with the same two-stage operation, but the order of operations are from left to The right to calculate, often make students into the mindset. In order to break the students’ mindsets, teachers are required to make the students master the order of mixed operations in their teaching. According to the teaching problems above, teaching methods of elementary mathematics mixed operation are discussed.
