虽然计算教学是小学数学教学的重要组成部分,但在具体的实施过程中,许多教师都反映学生的计算能力有所下降。针对这一情况,笔者谈了自己的几点认识。一、忽视口算训练,导致计算困难在任教小学二年级的数学时,笔者发现学生在做“多位数乘一位数”和“有余数的除法”时,即使自己知道算理,能熟练地背出乘法口诀,可就是算不对,原因在于教师忽视了口算训练。口算是学生必须掌握的一项基本功,也是数
Although computational teaching is an important part of elementary mathematics teaching, many teachers reflect the declining computational power of students in the concrete implementation process. In response to this situation, I talked about some of my own understanding. First, ignore the port count training, leading to calculation difficulties In the teaching of second grade mathematics, I found that students are doing “multi-digit by a number ” and “” the remainder of the division ", even if you know that arithmetic , Can skillfully back out multiplication formulas, but that is not right, because teachers ignore the mouth count training. Mouth count is a basic skill students must master, but also the number
