But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it?

    三、利用乘法口訣進(jìn)行計(jì)算1.復(fù)習(xí)口訣的含義。任意挑出一句乘法口訣(兩個(gè)因數(shù)不同的),讓學(xué)生說說它表示什么意思。如"七八五十六",使學(xué)生知道它既表示8個(gè)7相加是56,又表示?個(gè)8相加是56。2.以游戲的方式開展用口訣進(jìn)行計(jì)算的活動(dòng)。(1)已知兩個(gè)因數(shù)求積的游戲。方法是:請一位學(xué)生隨意說出一個(gè)兩位數(shù),另一位學(xué)生則將這個(gè)兩位數(shù)的十位數(shù)字與個(gè)位數(shù)字相乘,并算出結(jié)果,如果結(jié)果又是一個(gè)兩位數(shù),再將這個(gè)兩位數(shù)的十位數(shù)字和個(gè)位數(shù)字相乘,直至結(jié)果是一位數(shù)或零。如,一位學(xué)生說:"79",另一位學(xué)生則口算:7X9=636X3=181X8=8;一位學(xué)生說:"58":另一位學(xué)生口算:5X8=404X0=0(告訴學(xué)生0和一個(gè)數(shù)相乘得零)一位學(xué)生報(bào)了3個(gè)數(shù)以后,互換角色進(jìn)行。(2)已知積求兩個(gè)因數(shù)的游戲。

    (6)交流。6的乘法口訣一共有幾句?口訣中的第一個(gè)數(shù)與算式中的第二個(gè)因數(shù)相同,表示什么?口訣中的第二個(gè)數(shù)與算式的第一個(gè)因數(shù)相同,表示什么?相鄰兩句口訣的積相差幾?哪幾句難記一些?你用什么方法記呢?怎樣記住"三六十八"、"四六二十四"兩句口訣?教師在學(xué)生發(fā)言的基礎(chǔ)上鼓勵(lì)學(xué)生大膽說、想出不同記口訣的方法。(7)應(yīng)用"做一做"第1題(學(xué)生半獨(dú)立完成):①用6根小棒擺1個(gè)六邊形;②擺2個(gè)六邊形要用多少根小棒?你是怎樣想的?(想口訣"二六十二"。)③運(yùn)用所學(xué)的口訣口答擺4個(gè)、6個(gè)、3個(gè)、5個(gè)六邊形所需要向小棒數(shù)。"做一做"第2題(獨(dú)立完成):①將第2題改為填空題,在圓圈內(nèi)填寫正確的積;②口答得數(shù),并說一說所用口訣。

    人教版新課標(biāo)小學(xué)數(shù)學(xué)二年級(jí)上冊兩位數(shù)加兩位數(shù)(進(jìn)位加) 說課稿2篇

    一、說教材:本課時(shí)主要的內(nèi)容就是讓學(xué)生在情境中掌握兩位數(shù)加兩位數(shù)的進(jìn)位加法計(jì)算,讓學(xué)生通過嘗試和探索出多種算法,體驗(yàn)多種算法,然后比較出最好的算法。教學(xué)目標(biāo):1、通過具體的情境使學(xué)生更一步的理解加法的意義和提高學(xué)生的估算意識(shí)。2、通過學(xué)生的合作學(xué)習(xí)從而能探討出多種計(jì)算兩位數(shù)減兩位退位減法的方法。3、培養(yǎng)學(xué)生的數(shù)學(xué)口語表達(dá)能力,提高學(xué)生的學(xué)習(xí)興趣。4、掌握兩位數(shù)加兩位數(shù)(進(jìn)位加)豎式的寫法。重點(diǎn):(1)通過學(xué)生的合作學(xué)習(xí)從而能探討出多種計(jì)算兩位數(shù)減兩位退位減法的方法。(2)掌握筆算加法的計(jì)算法則。難點(diǎn):對多樣化算法進(jìn)行優(yōu)化,達(dá)到正確完成計(jì)算。發(fā)展學(xué)生的估算意識(shí)、和探究意識(shí)和解決實(shí)際問題的能力。二、說教法:組織學(xué)生在前面計(jì)算的基礎(chǔ)上,自主探索出兩位數(shù)加兩位(進(jìn)位加)的計(jì)算方法,并通過交流、討論,達(dá)到對算法的優(yōu)化,在通過“試一試”、“算一算”、“想一想”等形式達(dá)到知識(shí)的掌握。
