学生对数学复习课往往不感兴趣,对概念复习课,更感乏味。我从教学实践中发现,在复习数学概念时,若能较好地运用下述几种方法,可使学生积极思考、兴趣盎然,收到较好的复习效果。一、比较法。如复习“整除”和“除尽”时,出示一组题:将被除数能被除数除尽的算式用( )括起来,被除数能被除数整除的用( )括起来:15÷3=5,55÷1.1=50,15÷2=7.5,2.4÷0.2=12。学生练习后,让他们讨论、比较,明确这两个
Students are often not interested in mathematics review classes, the concept of review classes, more boring. I found from teaching practice that when reviewing the concepts of mathematics, if we can make good use of the following methods, we can make students think actively, are interested and receive better reviewing results. First, more law. For example, when reviewing “Divide” and “Divide”, we show a group of questions: To enclose the divisor divisible by (), divide the divisor by (): Divide by (): 15 ÷ 3 = 5,55 ÷ 1.1 = 50, 15 ÷ 2 = 7.5, 2.4 ÷ 0.2 = 12. Students practice, let them discuss, compare, clear these two
