小学数学课程的教学模式遵循由简到繁,由易到难,由浅入深。因此一般在小学低年级阶段数学知识逻辑较简单易懂,学生的计算能力也比较稳定,学习理解能力也会较好。通常是到了中年级后,学生会感到数学中计算方式越来越多,计算能力和逻辑思维也会有所下降。如何提高小学数学中年级学生的计算能力与逻辑思维,就是要探究的重点。 Elementary mathematics curriculum teaching mode to follow from simple to complex, from easy to difficult, from light to dark. Therefore, it is generally easier to understand the logic of mathematical knowledge in the lower grades of primary school. Students’ computational skills are also relatively stable, and their learning comprehension skills are better. Often after middle school, students feel more and more in math, with less computing power and logical thinking. How to improve the computational ability and logical thinking of the grade students in elementary mathematics is the key point to be explored.
