（2）记忆常数巧算方法20加减法表法120方数等求学生熟记达脱口出程度时常教学生巧算方法计算速度提高：数11相两边拉中间加满十前位进数525125相运巧算方法：
(2) memory and some commonly used data coincidence counting method as addition and subtraction multiplication table within 20 120 square number etc require students to memorize and to the point of blurt out at the same time often teach students some clever calculate way also can make its calculation speed is greatly increased such as is multiplied by a number from 11 on both sides of a pull a middle ten a into a forward with a number is multiplied by 5 25 125 can use opportunely calculate method
24×524÷2×10
24 * 24 present 2 * 5 10
324×25324÷4×100
25 324 present 4 x 324 x 324
409×125408×125+125408÷8×1000+125
409 * 125 408 * 125 + 125 408 present 8 x 1000 + 125
法试商法：差数试商法头商八九法（数数高位数字相时俗称头数前位数数数次高位数差超高位时直接八九试商）中数试商法折半试商法等等学生快算必须掌握基方法
try some division commercial law differential try to commercial law with the head in addition to business method (when the numbers on the dividend and the divisor that high phase at the same time commonly known as the head dividend top is smaller than the divisor and the divisor and dividend the number of times on the high error is less than the highest level can be directly used eight and nine test quotient) median try commercial law binary and commercial law and so on these are students quick is necessary to master the basic method
二理解算理提倡算法样化
学生会算必须明确算理求教师算法算理教学必须正确第印象非常重第次讲错难改掉记位心理学家说：首次感知新知识时进入脑信息受前摄抑制干扰学生脑皮层留深刻印象果首次感知准确造成良果短期难清教师必须充分备课选择优方案期达良教学效果
to make the student union must make it clear to calculate this requires teachers to the algorithm and the principle of teaching must be correct because the first impression is very important for the first time speak wrong it is hard to remove it later remember a psychologist said first perception of new knowledge proactive inhibition of information into the brain can be affected by the interference can leave deep impression in students＇ brain cortex but if the first perception is not accurate the adverse consequences in the short term is difficult to remove therefore the teacher must fully preparation select the optimal scheme in order to achieve good teaching effect
学生明确算理基础提倡算法样化算法样化求学生种方法解决问题鼓励学生独立思考适合方法解决力运种方法没种需求学生种提倡算法样化注意方法优化学生想出种正确方法予肯定说服学生放弃落繁琐观点遵循优秀简洁方法样思维力断提高特中高年级提出种算法说明算理防止知然知然时起培养学生逻辑思维口头表达力作
in students is clear on the basis of to promote diversity algorithm diversity algorithm isn＇t required that every student enior each kind of algorithm can calculate make its own instructions in order to prevent the learning don＇t know why at the same time cultivate students＇ logical thinking and the role of oral expression ability
三重视估算教方法
third the value estimate teach method
日常生活生产实际中某计算测量结果法没必精确计算结果判断时估算方法房间家学校距离某楼房高度验渔民判断某片水域里鱼数量等重视学生估算力培养仅学生思
维更加灵活学生直觉思维力培养帮助时加强估算加深学生数字认识促进数感培养增强应数学意识提高解决实际问题力教学中常性贯穿估算技巧方法：
in our daily life and production practice some calculation and the measurement result can＇t get or there is no need to get the precise result or judgment is employed to estimate method such as the size of a room the distance from home to school a building height experienced fishermen who judge a number of fish in the water etc attention to the cultivation of students＇ ability to estimate therefore not only can make students＇ thinking more flexible but also for the cultivation of the students＇ ability of intuition thinking has a lot of help at the same time strengthen the estimation can deepen students understanding of digital promote the cultivation of number sense enhance the consciousness of applied mathematics improve the ability of solving practical problems in the teaching i regularly throughout some estimation techniques and methods
1似估算法实际计算中根情况两数时估时估估估便口算宜估算程中学生生活背景思维方式估算结果定样允许估算结果准确值间定范围误差正负误差均：
1 the approximate estimation in the actual calculation according to the number two at the same time for large or for small at the same time or a big one for small forecast so that verbal arithmetic is advisable estimation process because the student＇s life background the different way of thinking to estimate the results may not be the same therefore allow a certain range between estimation results with the accurate value of error of plus or minus error such as
783+945≈800+9001700
material 800 783 + 945 + 900 1700
3927÷35≈4000÷401000
3927 present 35 material present 40 4000 1000
2联系实际估算法计算数租车数量铺买砖等必须整数采进法铁皮做铁盒铁盒必须整数尾法
2 contact the actual estimation such as computing rent a car number floor number to buy brick etc must be an integer and must adopt into a do with tin tin box tin box must be an integer and must use the method to end

1 the present way of life new standard pointed out through to real life situations make students experience feel and understand the meaning of number and operations to be presented to students a lot of realistic background closely related to mathematics and the life as in teaching 36 x 4 i import in the following way a top 36 yuan how much do you need to buy 4 such blouse this way of life for the calculation type questions students are willing to accept
2日常生活数学化生活中处处数学街购买衣物约需带少钱需估算准备购买少件物品需统计计算教育学生留意身边数学家长买菜时特留心售货员快速算出结果时学估算巧算等方法帮着算算提高计算力
2 daily life mathematically everywhere in the life mathematics such as street to buy clothes about how much money need to take need to estimate ready to buy how many pieces of goods also need to statistics and computation so paying conscious attention to mathematics education to students while along with the parents to buy food pay special attention salesman is how to quickly calculate the results we learned at the same time also want to use the methods of estimation qiao is help to calculate a calculate in order to improve their computing power
五养成教育容忽视
良惯直接影响着计算速度准确率教学中发现学生计算题出错原会做心认学生养成良惯
good habits and directly affects the calculation speed and accuracy in the teaching i found that students＇ math error reasons not to do but not by heart so i think to make students form good habits as follows
1规范书写书写规范造成计算错误现象屡见鲜5连笔写计算步时误成87潦草写成1造成计算结果错误教师严格求学生书写格式身作榜样
1 written in the specification calculation error caused by writing is not standard phenomenon such as due to the 5 cursive writing when calculating the next step is mistakenly identified as 8 write a 7 scrawled 1 and cause calculation error teacher is strict with students writing format and lead by example being a good role model
2认真审题快速准确计算关键做道计算题千万急手首先仔细观察明确应该先计算步计算步找找方应巧算方法做心里数然认真计算谓磨刀误砍柴工学生改成审题误计算功
2 serious topic it is the key to the rapid and accurate calculation do every computational problems don＇t rush to laid hands on him first have to look carefully clear which step should be calculated which is calculated after step where to find a find method can be applied to calculation of do know and then carefully calculated it is called knife don＇t miss your job i can＇t give students changed to topic calculation work by mistake
3勤验算验算种惯种力题目否求验算求学生必须做逐渐养成学生良验算惯
3 diligently checking calculation is a kind of habit is also a kind of ability check whether subject requirement all students are required to have to do gradually to develop students＇ good habits of calculating
