Teaching objectives: 1. Experience the natural and interesting process of counting pictures, show the existing experience, and guide the students to know the correct counting method. 2, contact the actual life, the initial feeling of mathematics in the side, produce interest in learning mathematics. 3, cultivate students' observation ability. Teaching aids: underwater world maps, counting by form, all kinds of animal pictures. Teaching process: first, create situational conversation introduction: classmates, have you ever been to underwater world? It seems that everyone is interested in the underwater world, so let's go to the underwater world to have a look. (show the video data. The chart or the undersea world) Two, explore new knowledge 1, observe the scene map, teachers and students count together. (1) give you a few minutes to look at what's in the picture first (2) talking about each other. What do you see in this magical world? (3) who wants to talk about what you see? (a whale) teacher posted pictures of 1 whale on the blackboard. At the same time, the teacher answers the pictures of jellyfish, striped fish, shrimp and so on in the blackboard. (4) what kind of animals do you like most in the underwater world? How many are left? Find a few students to the number on the blackboard pointing to figure out your love chart animal. In the process of the students, teachers consciously guide students to order number and position of the penetration of related knowledge, let the students not only count the number and clear position in the map clock. 2, students count independently. Teacher: all students like counting, the teacher gives each student the chance to count, and write down the number of things, OK? (give students enough time to count) teacher: say something to each other, say, what you count, how you count, how much you count Teacher: what have we just counted? How many are there? When the students answer, the teacher paste the pictures on the blackboard and write the numbers Three, contact life, practice counting teacher: there are so many students like counting, then please students count our classroom things? Teacher: who will tell you what you count? How many? How do you count them?. Four, classroom summary of this lesson, we have met many friends in the beautiful undersea world, but also learned to count, go home and choose the number of items you like to listen to mom and Dad, okay? The campus the first unit of happiness - a unit of analysis, teaching content: the number of less than 10 of the number of read and write; less than 10 of the number; 10 less than the number of order; to distinguish between several and a few; and "=" "," "," "", and compare the 10 less than the size of a few. The focus is to understand the meaning of the 1 - 10 numbers, and to establish a preliminary sense of number and symbol. The difficulty is to write the number 1-10. Two, teaching objectives: 1, with the aid of specific items correctly count the number of objects within 10. 2, through the operation of specific activities, can understand the meaning of numbers less than 10, can read and write the number 0 - 10; about 10 less than the number of order in the specific situation, to distinguish between several and a few; with specific examples, understanding "=" "," "," "" meaning, and comparison of 10 less than the size of a few. 3, the initial experience with less than 10 of the description of things around the process. Under the guidance of teachers, learn to communicate with peers, initially formed a sense of cooperation, the number of feelings and daily life of close ties, experience the fun of learning mathematics. Three, teaching material analysis: this part of the teaching material is one of the most basic knowledge of students learning mathematics, but also the beginning of mathematics learning for primary school students. This unit is the initial stage of learning "number and Algebra" knowledge, which is of great significance to the establishment of a preliminary sense of number and symbol and the cultivation of students' interest in learning mathematics. Therefore, according to the age characteristics and cognitive laws of the children who have just entered school, they can provide students with hands-on experience and hands-on experience, and experience the process of abstracting from daily life, Let the students feel that mathematics comes from life. This unit is selected to the textbook characteristics of children will start the campus life as material, through science and technology "group activities", "chicken", "tug of war" and "happy classroom" four students interested in the comprehensive information map "context string", lets the student in a series of practical and challenging to solve the problem of the process, 10 less than the number of knowledge learning system. At the same time, cultivate students' awareness and ability to solve problems. There are four information windows in this unit. The first information window "technology, put forward the" group activities "by several aircraft" heaven, arouse students' interest in the information provided by the count, the figure also can count how many planes, there are a few friends in the visit, teaching materials selected only one of the problems which are guided by the number of to understand the significance of the number is less than 10, and the number of independent practice "about a few birds" infiltration estimation of primary consciousness of heaven. Second information window is by means of students are familiar with the "chicken" game, the number with another meaning of pigtail girl "the first few rows" in the perception of natural numbers, ordinal meaning; and by understanding the boy wearing a red jacket "on the 6 said what", and help the students to understand ordinal meaning. In the independent practice, with the "meal preparation" screen, learn 2 2 numbers of methods, preliminary penetration by group count method. Cultivate students' awareness of simple rules in sticking exercises. The third information windows are students' favorite tug of war competition, with the existing game experience of students, causing students to argue. The number of people on both sides is not equal, can not start the game, at the same time, this map has the characteristics of dynamic change, the children come in to make the number of both sides equal, can compete, so as to learn to compare the number of two. The fourth information window is a "happy classroom", which is presented in two comic strips, with the number of apples on the tree reduced to one, and there is no understanding of the 0 problem. At the same time, with the aid of the ruler and the 0 of the thermometer, we can see that 0 can not only represent a number, but also the starting point and the dividing line. In the independent practice, the content of "connecting in order" is designed, and the order of 0 - 10 is further understood. Four, teaching measures: 1, let students have a feeling of intimacy in mathematics learning activities, experience mathematics in the side. 2, teachers should encourage and guide students to find problems and put forward problems independently, and solve problems through cooperation. 3, make full use of independent practice, expand learning space. 4, let students gradually establish the sense of number and symbol in the specific situation 5, play the role of evaluation, stimulate students' learning. Five, the unit recommended class hours: 8 hours First class hours total second hours of information window, a happy campus teaching content: textbook fourth page information window 1, independent exercises first, third, sixth questions. Teaching objective: 1. The number of objects within 10 can be correctly counted with the help of topic maps and physical objects. 2. Abstract and understanding the meaning of numbers. 3, cultivate a preliminary awareness of the problem. Preview requirements: What do you draw in the 1. scene map? You can start from the 2. count, say? Teaching process: first, create scenarios, ask questions. 1, the students came to the new school, how do you think of this school? (student freedom) about the impression of school 2, now let's go to the playground and see the activities of the science and technology team! (scene map) 3. Please have a closer look and see what's on the map (sun, aircraft, children)? Guide students to learn orderly observation maps 4. Can you ask a question according to the content of the picture? Such as: "there are a few planes in the sky?" (students can not guide, to guide students to master the method of picture) two, independent exploration, solve the problem 1, want to know, "there are several planes in the sky?"" With what method? (count) teachers can organize the students to come up with a way we count how many plane in the sky, that the order of the count, Give encouragement to students who can count in order. 2, there are 5 planes in the sky, how can it be expressed? 3, can you still put forward such a mathematical problem? Students ask questions, and then let the whole class or deskmate solve the problem. Pay attention to the information in the map as much as possible. 4, 1, 2, 3? Except for 1 suns, 2 rockets, 3 little friends, what can they say? 5, for the students can not solve the problem of this class, let students collect in the "problem pockets", do a good job of recording. Three, consolidate and develop, practice 1, students find things in the classroom, count. 2, independent exercises first questions, first let the students say what is on the map Tell us what we're going to do (connect each group of objects to the corresponding number). You understand, come to solve. 3, independent exercises third questions,. 4, independent exercises eleventh questions, give students 3 seconds to see the sixth questions of the birds, students estimate how many birds in the sky Who is the best judge?. Estimated after count check. Let the students to observe the map and what can count. Four, classroom summary, through the study of this lesson, what have you learned? How do you feel? How do you like your performance in this class? What's the good news? What's not to be desired? Second hours of happy campus 1 - 5 of the teaching content: textbook 1 - 5 digital writing, "independent exercises" second, fourth, fifth questions. Teaching objective 1, write 1-5 numbers. 2, consolidate the understanding of the number of 1-10. 3, the close relationship between the number of feelings and daily life, experience the fun of learning mathematics. 4, enable students to learn to communicate with peers, and initially form a sense of cooperation. Teaching preparation: the teaching process of point diagram: first, create situation, reveal the subject: we learned to count, initially recognize 1-5 of these numbers. Come and be good friends with them today, and learn to write these numbers, OK? Two, observe the font, learn to write 1, first let the students watch the figures, say something like life. 2, observe the number of positions in grid. 3, note book, stroke. 4, 2, and try this digital writing "1" to allow students to write about their own line. "2" and "3" let the students to observe the position in the digital lattice, teacher on the blackboard "field" demonstration, students 2. Finally, write two more in the blanks. "4" and "5" these two numbers first let students observe, and then book empty practice, finally let the students write, write, compare, correct each other. Three, consolidate exercise 1, independent exercises second questions, according to the topic design, first let the students use the finger to represent the number, and then put a pendulum or draw a picture, finally write 1-5 number practice. 2, independent exercises fourth questions, preliminary penetration of statistical thinking, first let the students say what is on the map What do we need to do next to the form? Students can fill in the logarithm, but not too much. 3, independent practice fifth questions, students observe, let the students have to see, say this question let us do what. (according to a given number of a number, a corresponding circle as long as the number and number corresponding to coating can help students find out the rules again), a preliminary understanding of singular and dual. Four, after class reflection third hours, happy campus information window two teaching content: textbook eighth pages of information window 2 and independent exercises 1, 2, 3, 8 questions. Teaching objective: 1. Make the students understand the meaning of ordinal number and understand the meaning of the first. 2, can correctly distinguish between a few and a few. 3, experience the fun of learning mathematics. 4. Cultivate students' sense of number. Teaching process: first, create scenario 1, conversation: what kind of games do you like to play during the break? 2, we often carry out a variety of activities on the playground, let's go and see! (scene map) two, ask question 1, carefully observe the map, What do you know from the picture? (1) look at the picture 2) report the result of the observation. 2. What questions can you ask according to this picture? (1) independent thinking (2) communication within the group (3), communication between groups three, problem solving 1, pay attention to the problem from the students to select the number of questions to be learned in this class, such as "braids little girl row number"?" (teacher random blackboard writing problem) 2. What else can I ask? To solve the similar problems, such as: how many boys in white and yellow shoes? How to solve the problems in the picture and make the students understand the meaning of no.. Four, expand the application of 1, the students, we will soon open parents' meeting, you want to introduce their seat position to mom and Dad, how to say can make them hear clearly? What is the number of students in the first few rows, such as "in the first row"? Or the number from the back?" Let's judge if they're right. 2, independent exercises first questions riddle introduction: you guess what the answer is? Let's take a look at this rainbow and color it and paint the rainbow according to the requirements of the subject. 3, independent exercises, second questions in accordance with the number of lines, even after what is like? 4, independent exercises third questions, let the students clear the meaning of the picture, to solve the Yellow birds have a few? What's the number of green birds? Then compare the meanings of the two 4 representations. 5, independent practice eighth questions to the topic request count say small animal number and order, and then fill in the blanks. Preliminary knowledge of penetration. Four, classroom summary, through the study of this lesson, what have you learned? How do you feel? How do you like your performance in this class? Five, after class reflection: fourth hours happy campus 6 - 10 writing teaching content: textbook ninth pages 6 - 10 writing and independent exercises 2, 4, 5 questions. Teaching objectives: 1. Learn to write 6 - 10 numbers. 2. The composition of primary permeability number, counting by group and simple seeking law. 3, the close relationship between the number of feelings and daily life, experience the fun of learning mathematics. The teaching process: first, the creation of scenarios, reveal the subject: Mathematics Kingdom today can be lively, the original digital doll in a meeting, there are 6 views, 7, 8, 9, 10, five numbers, five numbers early because 1-5 and small friends, we will write this five number, can 6-10 have the opportunity to be friends with you, they can't wait to see them, you. (6, 7, 8 times, 9, 10) two, cooperative learning, inquiry method, 1 today, if you look carefully, learn to write these numbers, write them very well, they will become good friends with you. 2, learning style 6 (1): you can see small font 6 first, produce 6 (in grid in writing). See what it looks like (speaking, praising, encouraging the students to express their opinions) (2) learn the way of writing: take a look, speak about the position and layout of it in the case (let the students fully observe and speak fully). (3) write a book, try your own book, and instruct the writer to write. 3, learn 7, 8, 9, 10 of the writing (1) Division: 7, 8, 9, 10 also can not wait, they are in the book ninth pages waiting for you. (2) read books by themselves: students observe the characters themselves, which are like the shapes of the objects in their lives? Intra group communication. Then the class fully communicated. (3) write your own numbers. Practice first, then try writing. 4, have you learned? Any problems? Which number do you think is the most difficult to write? Ask students to be a teacher and further instruct writing. Three, consolidate and develop the practical application, 1, fourth by number of independent practice exercises. In practice, let the students observe the order of the first line and the second line according to the order. When the students are in trouble, the teacher can do the necessary instruction, and then write the number correctly. 2, independent exercises fifth questions, with bowl and hat figure, penetration number composition. When training, can use the hands of students learn out swinging, divided, and to Daniel understood. On this basis, the amount of exercise is enlarged, The teacher then designs his own numbers of exercises. 3, independent exercises sixth questions before meals to prepare chopsticks situation map. The main method for students to understand the number of counting is varied, can be a number, can also be the number of two, two penetration, according to group count. Practice, let students combine life experience to fill in the blanks, "prepared" (root) chopsticks". Can a number, can also be a pair of numbers, can also be determined according to the number of bowls. This question can be counted with the help of learning tools. After, guide the students to exchange different counting methods. 4, independent exercises seventh questions, this is a simple find the law of the subject. When you practice, let the students observe what they have in the picture, how they are arranged, and then find the corresponding graph to affix a paste, and then coordinate the rules of mutual arrangement. Four, classroom summary, through the study of this lesson, what have you learned? How do you feel? How do you like your performance in this class? What's the good news? What's not to be desired? Five, after class reflection:
