事实告诉我们,计算犹如数学知识的翅膀,数学成绩要多高,就看计算翅膀有多硬,因为数学测试中纯计算题占到三成,加上填空、判断、选择、解答题大多也离不开计算,粗略统计一下,计算得分占到五、六成之多,可见学生计算能力的培养是各年级的重点,那么,如何开展好小学数学计算教学呢?一、扎实基石身为高年级数学教师,每接一期新生,质检学生计算基石是头等大事,众览群山后,“九九乘法口诀”要人人过关,不仅要横背、竖背,还要斜背、倒背;学生
The facts tell us that the calculation of mathematical knowledge like the wings, the mathematical results to be much higher, to see how hard the calculation of the wings, as the math test purely accounted for 30%, plus fill in the blank, to judge, choose, Open calculation, rough statistics about the calculation of scores accounted for five or six as much, shows that the cultivation of students' computing power is the focus of all grades, then, how to carry out primary mathematics teaching? First, a solid foundation as a senior mathematics Teachers, each newborn, quality control students calculate the cornerstone is the top priority, after all the mountains, “Ninety-nine multiplication formulas ” everyone to cross the border, not only to cross the back, vertical back, but also oblique back, down Back
