探寻算理,提升运算能力

Exploring the Arithmetic and Improving Operational Capability

真实展现算理形成过程,让学生充分理解算理,会不断提高儿童的运算能力。在实际的运算教学中,教者可以借助一定的物化载体,引导学生领会算理,关注运算过程的探究,重视学生内化感悟。在计算教学课堂上运用四色学习单这一载体,让学生由易到难、探索算理,进而探究争鸣、发现算理,接着尊重差异、深悟算理,并能运用所掌握的数学原理,解决生活中的实际问题,体会运算所散发的魅力。

Show the formation process of arithmetic rationality and let students fully understand the arithmetic,which will continuously improve children’s operational capability.In practical operation teaching,teachers can guide students to understand calculation theory,pay attention to the exploration of operation process,and pay attention to the internalization of students’perception with the help of some materialized carriers.The four-color learning sheet is used in the calculation teaching class to enable students to explore the calculation principle from easy one to diffi cult one,and then to explore and fi nd the calculation principle.Thus,they can respect differences,deeply understand the calculation principle,and use the mathematical principles they have mastered to solve practical problems in life and realize the charm of calculation.
