学习了一些数学法则或题目以后,应让学生举出有关的例子,从中发现规律。这样,既便于学生掌握知识,又有利于培养能力。下面就一些简单问题举例如下: 1.两数之和两个自然数的和是多少,这是学生不难掌握的问题,但两个自然数的和是一定的算式有多少个?这是不被学生重视的,也是较为困难的。如自然数3和5的和是多少。学生很熟悉的算式:3+5=8。反过来,两个自然数的和是8的算式有多少个。可
After learning some mathematical rules or topics, students should be given examples to discover the laws. In this way, both for students to master knowledge, but also conducive to the development of ability. Here are some simple questions as follows: 1. What is the sum of two natural numbers and how many, which is not difficult to grasp the problem of students, but the sum of two natural numbers is a certain number of arithmetic? This is not a student Emphasis, but also more difficult. Such as the sum of natural numbers 3 and 5 is how much. Students are familiar with the formula: 3 + 5 = 8. In turn, how many of the formulas for the sum of two natural numbers is eight? can
