初一数学是初学数学的基础,要有效地提高教学质量,必须从初一抓起。特别要抓好学生运算能力的培养,学生的运算能力强了,以后的学习就变得更加的轻松。有理数被编为第一章,有着深刻的含义。有理数是小学数学教学的延伸,有着承前启后的作用。以有理数为载体,能拓展学生的思维,开阔学生的视野,提高学生的运算能力。
The first math is the basis of math at the beginning, to effectively improve the quality of teaching, we must start from the first. In particular, we must grasp the cultivation of students ’computing abilities, and the students’ computational ability is strong, and future learning becomes more relaxed. Rational numbers have been compiled into the first chapter, has a profound meaning. Rational numbers are an extension of elementary mathematics teaching and have a bearing on the past. Rational number as a carrier, can expand students’ thinking, broaden students’ horizons and improve students’ computing power.
