十一月十七日,我区擧行了五年級算术观摩教學,由我担任施教。教學內容是高小算術課本第一册第287題至第293題。我考慮的教學要求是“使孿生知道根据两數的和與差求兩数的应用题的特點和解答方法。”教学時間是一節課。這節課的教學步驟是這樣的: 檢查了學生家庭作业以後,叫学生解答(分步列式,並加验算)兩個应用題:①甲乙兩人把棉花卖給國家,甲卖出30斤,乙卖出20斤,甲比乙多卖得42,000元,各賣得多少元?②乙做桌子16張,甲做桌子此乙多做4張,兩人共做多少張桌子?並指定兩个學生板演,板演后還要把解答的步驟從頭到尾講述一遍。

Teaching content is high and small arithmetic textbook first volumes from the first 287 to the first 293 questions. The teaching requirement that I am considering is “to give the twins the character and solution to the problem of applying the sum of the two and the number of the difference.” Teaching time is a lesson. This lesson teaching steps is this: After examining the students homework, called the students answer (step by step, and plus checking) two application questions: ① A and B sold the cotton to the country, a sold 30 pounds , B sold 20 pounds, more than B sold for 42,000 yuan, how many sell each? ② B to do the table 16, A table to do this B to do more than 4, how many do two tables? And designated two A student board performance, after the board play but also to explain the steps from start to finish to talk about it again.
