应用题是小学数学的重要内容之一,也是教学中的重难点。解应用题主要是透过题中的文理、事理与算理,把握题中的数量关系,从而寻找解题的方法和途径。由于应用题的数量关系都具有抽象性和隐蔽性的特点,所以很多学生都感到解应用题困难。为了帮助学生准确地理解数量关系,提高解题能力。教学中,我以画线段图为教学手段,收到很好的教学效果。 Application is an important part of primary mathematics, teaching is also a heavy difficulty. Solve the application problem is mainly through the text of the problem, affair and arithmetic, to grasp the quantitative relationship between the number of questions in order to find ways and means to solve the problem. Due to the relationship between the number of questions are abstract and covert characteristics, so many students feel the problem of application problems. In order to help students understand the quantitative relationship accurately, improve their ability to solve problems. Teaching, I draw the line diagram for teaching methods, received good teaching results.
