幼儿6的减法教案1
活动目标
1、讲述自己的购物过程，学习用数字和符号记录。
2、学习用类推的方法，解答一些简单的数学问题。
活动准备
1、超市场景及贴有1—4元价格标签的商品若干。
2、幼儿人手一张5元面值的人民币，1元、2元、5元面值的人民币若干。
活动过程
一、购物活动，学习5以内的加减。
1、教师提出购物要求：
每位小朋友用5元钱买一样物品，如果需要找零钱，请在旁边的篓子里按数目取出零钱，再说说你的5元钱是怎么用的。
2、用一道算式记录下来。
你有几元钱，用了几元钱，还剩几元钱。
3、鼓励幼儿在购物过程中边购物边讲述。
如：我用5元钱，买了4元钱的牙膏，还剩1元钱。
(用一道算式记录，并和同伴交流算式表示的意思。)
4、请个别幼儿根据所列的算式讲述自己的购物情况。
(如：5-2=3，我用5元钱，买了2元钱的食品，还剩3元钱。)
二、带领幼儿进行购物猜测活动，学习用推类的方法解答一些简单的数学问题。
1、引导幼儿观察图片
知道实物图上数字的含义，教师提出问题，引发幼儿猜测：
教师：我用5元钱，买了货架图上的两样食品，你们猜猜我买的'是哪样食品?
2、当幼儿说出两样食品后，教师可请大家判断对错并说出理由，再肯定其中的一样食品，让幼儿重新猜另一样食品。
(如：幼儿猜出的是4元钱的可乐和1元钱的糖，因为这两样食品合起来是5元钱。)

1.复习5的分合,在掌握5的分合的基础上,学习5的加减..
2.进一步理解加减的实际意义,会解决生活中的简单的加减问题.能根据分合式说出加减法算式.
3.在活动过程中体验算式的乐趣活动准备物质准备：背景图一幅,活动动物卡片(小兔子5只),5的加减算式2+3=53+2=55-2=35-3=2,5的分合式.幼儿书写用具物质准备：幼儿已有5的分合知识.
活动过程一、复习5的分合。
1.出示5的分合式，请幼儿认读。
2.游戏：碰球(复习5的分合)师：嘿嘿嘿，我的1球碰几球?幼儿：嘿嘿嘿，你的1球碰4球，1和4合起来是5。(依次说完5的分合)二、新授5的加减。
a1.出示背景图，老师边操作边讲解：草地上先跳来了2只小兔子，又跳来了3只小兔子，现在，草地上一共有几只小兔子?
2.指定幼儿回答。
3.启发幼儿说出用什么方法算出来的?
4.请幼儿口头说出算式。
5.老师出示算式卡，全班幼儿齐声读算式。(2+3=5)6.提问：如果草地上先跳来3只兔子，后跳来2只兔子，应该怎样说出算式?
7.请一名幼儿说出相关的算式(3+2=5)8.比较两道加法算式的异同。
9.拓展练习：8+9=17b1.老师再次出示背景图，操作并讲解：草地上的5只小兔子，有2只玩累了，先回家了，现在草地上有几只兔子?
2.指定幼儿回答并说出用什么方法算出来的?
3.请幼儿口头说出算式。
4.老师出示算式卡，全班幼儿齐声读算式。(5-2=3)5.提问：如果先跳走了3只兔子，还剩下几只兔子?
6.请幼儿交流、讨论并回答。(5-3=2)7.比较两道减法算式的异同。
c游戏：你问我答师：小朋友，我问你，23=?生：老师，告诉你2+3=5依次说完所有的'算式。游戏熟悉后，可以让孩子们互相提问回答，巩固加减法计算.
d抢答:看谁最快?
老师准备一些口头的加减法应用题,师读生抢答,比一比,谁最快?例如:河里游来了3只鸭子,又游来了2只鸭子,一共有几只鸭子?(答得多又对的为胜,可以得到老师的奖励教师总结：表扬积极回答问题的小朋友，鼓励相对不积极的幼儿，再次带领幼儿巩固知识活动延伸请小朋友把今天学到的加减法与自己爸爸妈妈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.
- Encourage responses and explain that subtraction is taking away or removing objects or numbers from a group to find the difference.
- Show a visual representation with counters or manipulatives to help children understand visually.
2. Subtraction Song (10 minutes):
- Teach children a subtraction song to engage their auditory senses.
- Use catchy tunes and simple lyrics to help children remember the concept of subtraction.
- Practice singing the song a few times together.
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.
