在数学教学内容的板块中,计算是学生最容易掌握的一块内容,但也是出现错误最多的一块内容。在平时的教学中,这也是我们老师最感头痛的一件事。就拿小数乘法的计算来说,它涉及乘法口诀的熟练运用及加法的熟练计算,因此出现的错误率较高。一、学生小数乘法错例的共性问题1.字迹潦草、涂改进入高年级,学生用水笔或钢笔书写,一旦写错,第一反应就是在错字上改或涂,这样一来,连自己写的是哪个数也认不清了,导致结果 In the mathematics teaching content of the plate, the calculation is the most easy to grasp a piece of content, but also the most mistakes in a piece of content. In normal teaching, this is one of the most troubling things for our teachers. Take the calculation of fractional multiplication, it involves the skilled use of multiplication formulas and the skilled calculation of addition, so the error rate is higher. First, the students multiplication of the law of the common problem of wrong examples 1 illegible, altered to enter the upper grades, students with pen or pen to write, once wrong, the first reaction is to change or paint on the wrong words, so even write their own Which number is also not clear, leading to the result
