在小学数学教学中应该重视培养学生初步的逻辑表达能力和阅读审题能力。初步的逻辑表达能力,是指学生对自己的数学行为,如计算、判断,解题等的思路,能用口头和书面语言有条理、有根据,正确地表达出来的能力。用这样的两道题让五年级学生做,“3是6的因数吗?为什么?”“3是6的约数吗?为什么?”几乎全部学生,对每道题的前一问都能作出正确的结论“3是6的因数”、“3是6的约数”。而后者“为什么?”这需要给结论提出依据。“3×2=6”、“6能被3整除”一般学生也是掌握的。但
In elementary mathematics teaching, we should attach great importance to cultivating students' initial logical expression ability and reading examination ability. The initial ability of logical expression refers to the students' ability to express their math behavior, such as the way of calculating, judging, solving problems and so on, in an organized and well-founded way with verbal and written language. With these two questions for fifth graders, “3 is a factor of 6? Why?” “3 is a divisor of 6? Why?” Almost all students, each question can be made before the first question The correct conclusion is that “3 is a factor of 6” and “3 is a divisor of 6”. The latter “why?” This needs to be based on conclusions. “3 × 2 = 6”, “6 can be divisible by 3” The average student is also mastered. but
