应用题是数学教学中的重点,采用列方程的方法是解决数学应用题的有效途径。为了解决中小学数学列方程的困难,本文提出了句子分析的方法。通过对数学应用题句子的句型、成份分析,假设未知数,将句子变为表达式和方程式,通过求解方程式得到应用题的答案。该方法克服了列方程难点,有助于求解数学应用题。
Applied questions are the key points in mathematics teaching. The method of using column equation is an effective way to solve math problems. In order to solve the difficulty of maths equations in primary and secondary schools, this paper proposes a sentence analysis method. By applying sentence patterns, composition analysis, hypothesis unknowns, sentences into expressions and equations for mathematical application questions, the answers to applied questions are obtained by solving the equations. This method overcomes the difficulty of column equations and helps to solve math problems.
