方程法优于算术法。在小学阶段，教会学生在解简易方程的基础上，进一步学会列方程解答应用题，既是提高小学生灵活解答应用题能力的基本要求，又是搞好中小学数学教学衔接的重要措施。然而，多数小学生因受算术解法干扰，在学习过程中，列方程解题还是比较被动的。如何改... Equation method is superior to arithmetic method. In the elementary school, on the basis of solving the simplified equations, the church students further learned how to solve the application of the column equation. This not only serves as a basic requirement to improve the ability of primary school students to answer questions flexibly, but also serves as an important measure to improve the connection between primary and secondary mathematics teaching. However, most of the primary students interfere with the solution of the arithmetic solution. In the process of learning, solving the column equation is still relatively passive. How to change ...
