（一）、創(chuàng)設(shè)情景,導(dǎo)入新課摸牌游戲：三位同學(xué)持三組牌，指定三位同學(xué)分別任意摸出一張,看誰(shuí)能摸到紅牌，他們一定能摸到紅牌嗎?請(qǐng)手持牌的同學(xué)根據(jù)自已手中牌的情況，用語(yǔ)言描述一下抽出紅牌的情況?？偨Y(jié)：在一定條件下，有些事情我們事先能肯定它一定發(fā)生，這些事情成為 事件。有些事情我們事先能肯定它一定不會(huì)發(fā)生，這些事情稱為 事件。 事件和 事件統(tǒng)稱為確定事件。許多事情我們事先無法肯定它會(huì)不會(huì)發(fā)生，這些事情稱為 事件，也稱為 事件。
李商隱詩(shī)兩首教學(xué)設(shè)計(jì)教案
我們不妨將主旨放在“莊生曉夢(mèng)迷蝴蝶，望帝春心托杜鵑。滄海月明珠有淚，藍(lán)田日暖玉生煙?！倍?lián)之前，那么，事情就變得簡(jiǎn)單起來了：華年如莊生曉夢(mèng)迷蝴蝶；華年如望帝春心托杜鵑；華年如滄海月明珠有淚；華年如藍(lán)田日暖玉生煙。從課下注釋，我們很容易就可以看出，這四句每一句都在用典。因此，我們通過對(duì)典故的解讀，然后加以整理，將其理順，似乎就可以完成對(duì)詩(shī)歌內(nèi)容的解讀；至于什么悼亡、愛情，不妨拋之腦后，畢竟，沒有那些其他的主題，也并沒有讓詩(shī)歌失色，而加上這些捉摸不定的主題，只是讓詩(shī)歌增加了所謂的神秘色彩，徒增閱讀難度而已。

3）乘除運(yùn)算①有理數(shù)的乘法法則：（老師給出，學(xué)生一起朗讀）1. 兩數(shù)相乘，同號(hào)得正，異號(hào)得負(fù)，并把絕對(duì)值相乘；2. 任何數(shù)與零相乘都得零；3. 幾個(gè)不等于零的數(shù)相乘，積的符號(hào)由負(fù)因數(shù)的個(gè)數(shù)決定，當(dāng)負(fù)因數(shù)有奇數(shù)個(gè)數(shù)，積為負(fù)；當(dāng)負(fù)因數(shù)的個(gè)數(shù)為偶數(shù)個(gè)時(shí)，積為正；4. 幾個(gè)有理數(shù)相乘，若其中有一個(gè)為零，積就為零。②有理數(shù)的除法法則：（老師提問，學(xué)生回答）1. 兩個(gè)有理數(shù)相除，同號(hào)得正，異號(hào)得負(fù)，并把絕對(duì)值相除；2. 除以一個(gè)數(shù)等于乘以這個(gè)數(shù)的倒數(shù)。③關(guān)系（老師給出）除法轉(zhuǎn)化為乘法進(jìn)行運(yùn)算。
