分数、百分数应用题是小学数学的重要基础知识,也是教学上被称为“老大难”的问题。教学中,我从引导学生弄清分率的含义入手,再教会他们确定标准数和比较数的方法,然后交给他们解此类应用题的钥匙,收到了较好的较果。 Fraction, the percentage of application questions is an important basic knowledge of elementary mathematics, teaching is also known as the “grand difficult” issue. In teaching, I started with guiding students to clarify the meaning of fractional rates, taught them to determine the standard number and comparison method, and then gave them the key to solve such problems, and received better results.
