新编小学珠算课本的教学要求是:使学生掌握珠算的基础知识和计算能力,能灵活地运用它来解决生产和日常生活中一般性的计算问题。要求学生背熟珠算口诀,练活手指,拨珠时能得心应手,能正确而且迅速地进行计算,还要求学生获得一些记账的初步知识。新编课本主要讲整数和小数的四则计算。由于实际计算中的乘数和除数多是多位数的,现行珠算课本里的乘、除数只到三位,是不够用的,新课本增加了乘、除数是四位以 The new primary school abacus textbooks teaching requirements are: to enable students to master abacus basic knowledge and computing power, flexibility to use it to solve the general calculation of production and daily life. Students are required to practice abacus formulas, practice their fingers, move their beads with ease, make correct and prompt calculations, and require students to gain some initial knowledge of accounting. The new textbook focuses on the four calculations of integers and decimals. As the multipliers and divisors in the actual calculation are mostly multi-digit, it is not enough for the multiplication and division in the current abacus textbooks to be only three. The new textbook multiplies the multiplication by a factor of four
