苏教版小学《数学》教材中都设置了一些思考题,在六年级上册第42页有这样一道思考题:先计算,再观察每组算式的得数,能发现什么规律?(1)1/2-1/3=()1/2×1/3=()(2)1/4-1/5=()1/4×1/5=()对于这个思考题,我们可以给学生提出问题:你能根据发现的规律再写几组这样的算式吗?除了分子是1有这样的规律,分子是其他的数有这样的规律吗?“差等于积”的两个数有 There are some questions in the “Mathematics” textbook for the Sujiao Version Primary School. In the sixth grade, page 42, there is such a question: first calculate and then observe the number of each set of the formula, and what law can be found? / 2-1 / 3 = (1/2 × 1/3 = (2) 1 / 4-1 / 5 = () 1/4 × 1/5 = () For this question, we can give Students ask questions: Can you write another set of such formulas according to the law of discovery? Except for the numerator 1, there is such a rule that the numerator is the same for other numbers. “The difference between two numbers equal to the product” Have
