    【反思】本節(jié)課的教學注重體現了情境教學在教學中的運用。課堂上體現了這樣幾個特點:1.數學知識與生活實際相結合。數學來源于生活,生活中處處有數學。小學生對熟悉的生活情境和事物感興趣。所以我從他們熟悉的事物中尋找教學題材,設計了有趣的情景教學。讓學生感到數學知識就在他們身邊,感到數學的作用,設計了作息時間表。這樣,既鞏固了時間的知識。又可以教育學生在生活中要合理安排時間,不要浪費時間,做時間的主人。2.注重在學習中自主探究,合作交流。在教學《時間的計算》時,讓學生用自己制作的學具表親自動手撥一撥,想一想讓他們主動嘗試自主發(fā)展。教學例2時讓他們小組合作交流學習方法。這些都體現了培養(yǎng)學生的能力.自主探究的精神。

    3、在學生已有了乘法口訣的數學模式后,引導學生運用已有經驗,親自參與其它乘法口訣的學習,充分發(fā)揮學生的主體作用,發(fā)展學生的思維。4、多采用提問讓學生思考的方法,讓學生在操作過程中想老師提出的問題,培養(yǎng)學生的抽象概括能力。如:在擺了兩根小棒后問學生:現在擺了幾根小棒?可以用幾表示?擺了幾個2根?用乘法算式應怎樣表示等。5、運用磁性黑板擺實物,讓學生能夠通過觀察實物直觀感知,如:問2個2是多少?學生實在不能想的可以通過看圖數數來完成,這樣便可以照顧學習有困難的學生。學生已經對乘法的含義有了初步的理解,掌握口訣就比較容易;但是,要熟記乘法口訣并準確的運用還需花較大的精力和時間,因此,要引導學生學會由加法到乘法,再到口訣的歸納法,由易到難,循序漸進的方法。如:2個2,可以用加法22=4,再到寫乘法算式2×2=4,再歸納出口訣“二二得四”;先引導學生說出1個2是多少?編出口訣,再引導說出2個2是多少,編出口訣等等。

    【說教材分析】本節(jié)課的教學內容是千以內數的大小比較,教材把比較數的大小分為兩種情況:位數相同的數比較大小,位數不同的數比較大小。是在學生掌握了百以內數的大小比較方法,能認讀千以內數,理解數的組成的基礎上開展教學的。而且在實際生活中,學生積累了大量感性經驗,學生已經能初步感知、判斷出數的大小。本節(jié)課的重點首先應達成知識技能目標,學生自主探究出千以內數的大小比較方法,能正確、快速比較出千以內數的大小,在大量的、多種形式的練習中培養(yǎng)學生的數感。教材沒有將比較數的大小的方法歸納概括出來,是放手讓學生自主觀察、比較、分析、概括,合作商量,在學生充分表達、交流自己的想法的過程中,讓學生自己發(fā)現、總結出數的大小比較方法。其次,在實際應用中讓學生體會到生活中對數的應用的廣泛性、實用性,從而強化所學知識,獲得積極的情感體驗。
