所谓的“珠心算”就是在大脑里打算盘,把打算盘操作的过程内化到心里中去,凭借着内化的“算盘”在头脑中进行加减乘除等一系列运算。珠心算是按群计算的,可以让学生进行大位数的运算,充分提高运算效率,而且珠心算按照“五升十进制”的计算规律,能使计算的难度降低。一、珠心算在小学中的运用成果首先,珠心算可以让小学生更加清楚、直观地认识数字。在小学数学教学中,教师往往采用实物来帮助学生认识数字。如,刚入学一年级的学生,要教他们认识数字,就用数
The so-called “Abacus ” is the intention of the plate in the brain, the operation of the process of internalizing the plate to the heart, with internalized “abacus ” in the mind of a series of operations such as addition, subtraction and multiplication. Abacus calculation is based on the group, allowing students to carry out large-digit operations, and fully improve the efficiency of computing, and the abacus calculation in accordance with “five liters decimal ” calculation can reduce the difficulty of the calculation. First, abacus calculation results in the use of primary school First of all, abacus calculation allows primary students more clearly and intuitively understand the figures. In elementary mathematics teaching, teachers often use physical objects to help students understand numbers. For example, students who have just entered the first grade should teach them to know the numbers and use them
