2019-2020年北京版六年下《空間與圖形》word教案 教學(xué)目標(biāo)： 1.使學(xué)生加深對直線、射線和線段特征的認(rèn)識，進(jìn)一步理解它們之間的關(guān)系，豐富對角的概念的理解,完善認(rèn)知結(jié)構(gòu)。 2．使學(xué)生進(jìn)一步積累認(rèn)識立體圖形的學(xué)習(xí)經(jīng)驗，增強(qiáng)空間觀念，發(fā)展數(shù)學(xué)思考。 教學(xué)重點： 使學(xué)生加深對直線、射線和線段、角等特征的認(rèn)識，進(jìn)一步理解它們之間的關(guān)系。 教學(xué)難點： 用量角器量角、畫角，理解垂直與平行的關(guān)系，畫垂線 教學(xué)過程： 一、知識梳理，形成網(wǎng)絡(luò) 1.提出要求： ①分別畫一條直線、一條射線和一條線段。 ②看圖說說直線、射線和線段的相同點和不同點。 ③說說直線、射線和線段的關(guān)系。 ④在紙上畫出兩條直線 2.根據(jù)學(xué)生的回答小結(jié)： 同一平面內(nèi)兩條直線的關(guān)系，并板書。 a相交（當(dāng)兩條直線相交成相交直角時，這兩條直線互相垂直） b不相交（當(dāng)兩條直線不相交時這兩條直線互相平行） 二、鞏固練習(xí)，反饋校正 完成教科書第100頁“練習(xí)十九” （1）完成第2題：讓學(xué)生列舉生活中的事例 先分小組說，再全班交流 （2）完成第3題：先讓學(xué)生觀察圖形，再獨立思考，最后指導(dǎo)學(xué)生用兩點決定一條直線的知識說明。 （3）完成第4題：先讓學(xué)生討論：通過一個點可以畫多少條直線？通過兩個點呢？再指導(dǎo)學(xué)生用兩點之間的連線最短的知識說明 （4）完成第5題：指導(dǎo)學(xué)生說思考過程時，師著重指出：因為從直線外的一點到直線的所有線段中，垂直的線段是最短的，因此從A或B點出發(fā)，連通主管道的小管道應(yīng)該與主管道相應(yīng)部分垂直。最后讓學(xué)生獨立操作。 三、拓展延伸，整理反思 1.師提問：我們學(xué)過哪些角？你能填寫下表嗎？學(xué)生獨立做好后全班交流。 名稱 （）角 （）角 （）角 （）角 （）角 圖形 特征 2.師讓學(xué)生用活動角演示上面的各種角，引導(dǎo)學(xué)生進(jìn)一步思考：角的大小與什么有關(guān)？學(xué)生討論后，師小結(jié)：角的大小與兩條邊叉開的大小有關(guān)。 3.完成教科書第101頁“練習(xí)十九” 第6題 學(xué)生獨立填后反饋校對。 4.畫角、量角器量角 （1）讓學(xué)生說一說用量角器量角的方法。 （2）師讓學(xué)生嘗試畫45度和135度的角各一個，在用量角器量，并讓學(xué)生對比，這兩個角畫時和量時有什么不同？要注意什么？ （3）完成教科書第101頁“練習(xí)十九” 第7題 5.補(bǔ)充練習(xí)： 判斷： （1）一條直線5千米。 （2）經(jīng)過兩點可以畫無數(shù)條直線 。 （3）角的邊越長，角就越大。 四、全課總結(jié) 通過這一課的學(xué)習(xí)你學(xué)到了什么？還有什么不懂？ 附送： 2019-2020年北京版六年級下冊英語期末試卷 聽力部分 一、聽，給圖片標(biāo)號。 二、聽短文，選擇正確答案： 1.
