幼兒6的減法教案1

　　活動目標

　　1、講述自己的購物過程，學習用數(shù)字和符號記錄。

　　2、學習用類推的方法，解答一些簡單的數(shù)學問題。

　　活動準備

　　1、超市場景及貼有1—4元價格標簽的商品若干。

　　2、幼兒人手一張5元面值的人民幣，1元、2元、5元面值的人民幣若干。

　　活動過程

　　一、購物活動，學習5以內(nèi)的加減。

　　1、教師提出購物要求：

　　每位小朋友用5元錢買一樣物品，如果需要找零錢，請在旁邊的簍子里按數(shù)目取出零錢，再說說你的5元錢是怎么用的。

　　2、用一道算式記錄下來。

　　你有幾元錢，用了幾元錢，還剩幾元錢。

　　3、鼓勵幼兒在購物過程中邊購物邊講述。

　　如：我用5元錢，買了4元錢的牙膏，還剩1元錢。

　　(用一道算式記錄，并和同伴交流算式表示的意思。)

　　4、請個別幼兒根據(jù)所列的算式講述自己的購物情況。

　　(如：5-2=3，我用5元錢，買了2元錢的食品，還剩3元錢。)

　　二、帶領(lǐng)幼兒進行購物猜測活動，學習用推類的方法解答一些簡單的數(shù)學問題。

　　1、引導(dǎo)幼兒觀察圖片

　　知道實物圖上數(shù)字的含義，教師提出問題，引發(fā)幼兒猜測：

　　教師：我用5元錢，買了貨架圖上的兩樣食品，你們猜猜我買的'是哪樣食品?

　　2、當幼兒說出兩樣食品后，教師可請大家判斷對錯并說出理由，再肯定其中的一樣食品，讓幼兒重新猜另一樣食品。

　　(如：幼兒猜出的是4元錢的可樂和1元錢的糖，因為這兩樣食品合起來是5元錢。)

　　1.復(fù)習5的分合,在掌握5的分合的基礎(chǔ)上,學習5的加減..

　　2.進一步理解加減的實際意義,會解決生活中的簡單的加減問題.能根據(jù)分合式說出加減法算式.

　　3.在活動過程中體驗算式的樂趣活動準備物質(zhì)準備：背景圖一幅,活動動物卡片(小兔子5只),5的加減算式2+3=53+2=55-2=35-3=2,5的分合式.幼兒書寫用具物質(zhì)準備：幼兒已有5的分合知識.

　　活動過程一、復(fù)習5的分合。

　　1.出示5的分合式，請幼兒認讀。

　　2.游戲：碰球(復(fù)習5的分合)師：嘿嘿嘿，我的1球碰幾球?幼兒：嘿嘿嘿，你的1球碰4球，1和4合起來是5。(依次說完5的分合)二、新授5的加減。

　　a1.出示背景圖，老師邊操作邊講解：草地上先跳來了2只小兔子，又跳來了3只小兔子，現(xiàn)在，草地上一共有幾只小兔子?

　　2.指定幼兒回答。

　　3.啟發(fā)幼兒說出用什么方法算出來的?

　　4.請幼兒口頭說出算式。

　　5.老師出示算式卡，全班幼兒齊聲讀算式。(2+3=5)6.提問：如果草地上先跳來3只兔子，后跳來2只兔子，應(yīng)該怎樣說出算式?

　　7.請一名幼兒說出相關(guān)的算式(3+2=5)8.比較兩道加法算式的異同。

　　9.拓展練習：8+9=17b1.老師再次出示背景圖，操作并講解：草地上的5只小兔子，有2只玩累了，先回家了，現(xiàn)在草地上有幾只兔子?

　　2.指定幼兒回答并說出用什么方法算出來的?

　　3.請幼兒口頭說出算式。

　　4.老師出示算式卡，全班幼兒齊聲讀算式。(5-2=3)5.提問：如果先跳走了3只兔子，還剩下幾只兔子?

　　6.請幼兒交流、討論并回答。(5-3=2)7.比較兩道減法算式的異同。

　　c游戲：你問我答師：小朋友，我問你，23=?生：老師，告訴你2+3=5依次說完所有的'算式。游戲熟悉后，可以讓孩子們互相提問回答，鞏固加減法計算.

　　d搶答:看誰最快?

　　老師準備一些口頭的加減法應(yīng)用題,師讀生搶答,比一比,誰最快?例如:河里游來了3只鴨子,又游來了2只鴨子,一共有幾只鴨子?(答得多又對的為勝,可以得到老師的獎勵教師總結(jié)：表揚積極回答問題的小朋友，鼓勵相對不積極的幼兒，再次帶領(lǐng)幼兒鞏固知識活動延伸請小朋友把今天學到的加減法與自己爸爸媽媽或者好朋友一起分享。

　　Title: Teaching Plan for Subtraction within 5 for Preschoolers

　　Introduction:

　　Subtraction is an important mathematical concept that allows children to understand the relationship between numbers and develop critical thinking skills. This teaching plan focuses on teaching subtraction within 5 to preschoolers. Through various interactive and engaging activities, children will not only learn how to subtract numbers but also develop a solid foundation in numeracy.

　　Objective:

　　By the end of this lesson, preschoolers will be able to:

　　1. Understand the concept of subtraction.

　　2. Recognize and use the minus (-) sign.

　　3. Perform subtraction within 5 accurately.

　　4. Apply subtraction skills to solve simple word problems.

　　Materials Needed:

　　1. Counters or other manipulatives.

　　2. Flashcards with numbers 0-5.

　　3. Whiteboard or blackboard.

　　4. Markers or chalk.

　　5. Worksheets with subtraction problems.

　　Lesson Plan:

　　1. Introduction (10 minutes):

　　- Begin the lesson by asking children if they know what subtraction means.

　　3. Mini-Exercise (10 minutes):

　　- Carry out a mini-exercise to ensure children grasp the concept.

　　- Use flashcards with numbers 0-5 and ask children to pick two cards.

　　- Demonstrate subtraction by removing the smaller number of objects from the larger number, using counters or manipulatives.

　　- Ask children to count the remaining objects and state the answer.

　　- Repeat the exercise with different numbers until children feel confident with simple subtraction.

　　4. Using the Minus Sign (10 minutes):

　　- Introduce the minus (-) sign as the symbol used for subtraction.

　　- Write a subtraction problem on the board, using the minus sign.

　　- Explain how to read and solve the problem.

　　- Encourage children to practice writing the minus sign on the whiteboard or blackboard.

　　5. Interactive Activities (20 minutes):

　　- Divide the children into pairs or small groups.

　　- Distribute worksheets with subtraction problems within 5.

　　- Instruct children to solve the problems using counters, manipulatives, or by drawing pictures to represent the objects being subtracted.

　　- Walk around the classroom to check individual progress and provide assistance if needed.

　　- Encourage children to discuss their solutions with their peers.

　　6. Word Problems (15 minutes):

　　- Present simple word problems related to subtraction within 5.

　　- Read the problems aloud, allowing children to understand the context.

　　- Encourage children to solve the problems using the strategies learned during the lesson.

　　- Discuss the answers as a class, allowing children to explain their thought processes.

　　7. Conclusion (5 minutes):

　　- Summarize the key points covered in the lesson.

　　- Review the concept of subtraction and the use of the minus sign.

　　- Allow children to ask questions or share their thoughts on the lesson.

　　- Provide positive reinforcement and praise for their efforts.

　　Extension Activities:

　　1. Play subtraction games using dice or number cards.

　　2. Create a subtraction scavenger hunt around the classroom or outdoor play area.

　　3. Reinforce learning through online interactive subtraction games and apps.

　　Note: The timing for each activity may vary depending on the pace and engagement of the children. It is important to adjust the lesson plan accordingly to suit the needs of the students.
