The first part of primary school mathematics teaching plan: teaching objectives;
1, so that students can understand and use the calculation method of adding two digits to one digit (without carrying) and can skillfully calculate these additions by mouth.
2. Enable students to use the addition they have learned to try to solve simple practical problems, accumulate experience in mathematical activities, feel the close connection between mathematics and real daily life, and enhance their mathematical consciousness.
3. Let students cooperate with their classmates in their study and guide them to think and practice actively. Cultivate students' enthusiasm for learning mathematics.
Teaching focus:
Learn and master the operation of adding and subtracting one digit from two digits (no carry, no abdication).
Teaching difficulties:
Apply what you have learned and solve practical problems.
Teaching tools:
Sticks, counters, cards, pictures, ppt
Teaching process:
First, create situations and introduce new lessons.
Teacher: Today, the teacher will introduce you to a new friend. (shows squirrel card) Who do you think this is?
Health: Little squirrel!
Teacher: Yes, it's a squirrel! Everyone is fine, so who knows what the little squirrel likes best?
Health: Pine cones!
Teacher: Students are so clever! Today, the little squirrel is very happy, because today is the birthday of the little squirrel, and the little squirrel and his mother go to pick his favorite pine cones. Let's see how many they picked! (Show ppt text situation map)
Second, cooperative inquiry, learning new knowledge
1, tell me about the mathematical information conveyed in the picture. (Explanations 25 and 4 contain ten and one. )
2. Ask a math problem according to the information in the picture?
(1) How many pinecones did the female squirrel step on more than the little squirrel?
(2) How many pinecones did the little squirrel pick less than the female squirrel?
(3) How many pinecones did the little squirrel and its mother pick? (Show question card)
3. Practice for students, let them speak and calculate. (Show Math Card)
4. How many pinecones did the female squirrel pick more than the little squirrel?
Equation solving, 25-4=2 1.
Question: 4 out of 20 or 4 out of 5? (pendulum calculation)
Are the four beads from ten or one? Why? (Call the counter to solve the problem)
Summary: Calculate 5-4= 1 first, then 20+ 1=2 1.
5. How many pinecones did the little squirrel pick less than the mother squirrel?
Equation solving, 25-4=2 1.
(Hint: The formula and algorithm of this problem are the same. )
6. Ask the students to work out a formula to find out how many pinecones the little squirrel and its mother stepped on.
25+4=29
Question: Do you put the four sticks in 5 or 20? Swing and calculate.
Are these four beads in groups of ten or one? Why? Call the counter to solve the problem.
(Summary: 5+4=9, then 20+9=29)
7. Take the students to play games (I'll give you some, there are differences between us)
Third, consolidate the practice.
Textbook exercise
Fourth, class summary.
Personize squirrels, lead students to find the mathematical information of squirrel picking pinecones, ask questions and solve problems. Students can think and communicate on their own initiative, and they don't need teachers to attract students' attention. Students can concentrate on learning knowledge in a natural and peaceful atmosphere and become the masters of learning.
Primary school mathematics teaching plan Part II: learning objectives;
1, with the help of existing life experience, exchange and cooperate in familiar life situations, and learn to read the whole process.
2, combined with daily routine, cultivate students' attitude of cherishing time and good habit of arranging time reasonably.
3, through observation, discussion, comparison and other activities, initially cultivate students' awareness of inquiry and cooperation.
Learning focus: 1, learn to know the hour hand and minute hand of a clock, and know the hour time on the clock.
Learning difficulties:
Learn two ways to express time.
Preparation of teaching AIDS: several props clocks, physical clocks and courseware.

First, preparation before class
1, Teacher: Students, look at those guests who came today? (Play the video clip of Pleasant Goat and Big Big Wolf)
2. Teacher: The lamb in Yangcun came to our classroom to have a class with us today. Look, the village chief Slow Sheep is going to play a puzzle for us. Do you want to play?
3. Hallows A: Yes.
4. Teacher: Then the teacher will invite a male classmate and a female classmate to compete on the platform! (Students raise their hands warmly to participate)
5. Teacher: Let's see which of them can finish this design fastest, shall we? (Boys and girls all shout come on)
6. Teacher: The results of the competition have come out. Do you know what they spelled?
7. Health: It's a clock.
8. Teacher: That's right. In this lesson, we will learn the clock (blackboard writing) together. Using jigsaw puzzles can stimulate students' interest in learning, stimulate their thirst for knowledge and create an active learning atmosphere. Students' puzzles show that students have a preliminary understanding of the clock face in their daily life experience. Teachers can reveal the problems according to the students' puzzles and naturally transfer the most basic understanding to the classroom.
Second, self-study Second, new teaching-knowing the clock face
1, Teacher: Now, please look carefully at what is on these two clocks.
Health 1: There are 12 large cells.
Health 2: There are two needles.
Health 3: There is a number 1- 12.
2. Teacher: Does the minute hand look the same as the hour hand?
Health: It's different. A long one, a short one, a thick one and a thin one.
Teacher: What's the name of the short and thick one? What's the name of the thin and long one?
Health: The short and thick is the hour hand, and the slender is the minute hand (blackboard writing: minute hand, hour hand).
Teacher: Do you know which direction the minute hand and the hour hand move? Show it with your little hand.
Health: The minute hand and the hour hand go in this direction (gesturing).
Teacher: This direction is clockwise. Hold out your right hand and do exercises with the teacher. Point clockwise and say. (class gestures)
Teacher: Do you know whether the minute hand is faster or the hour hand is faster?
Student: Minute hand
3. Teacher: Students, besides the minute hand and the hour hand, there is a thinner and longer second hand on the clock, which we will learn slowly in the future.
4. Teacher: Is there any good way for you to remember the position of the numbers 12?
Health 1: from 123 ... to 12.
Health 2: 12 middle
5. Teacher: Students, just now we learned the secret of the clock face. Meiyangyang said that it is time to test everyone. Let's have a look.
Health: OK.
Teacher: Look, Meiyangyang is so happy. It is satisfied with our answer. 1. It is in line with students' cognitive psychological characteristics to ask students to observe carefully from three aspects: eyes, heart and mouth, and to guide students to observe according to the steps of "occupying appearances"-"comparing differences"-"screening points".
2. Let students make gestures, feel the direction of the minute hand and the hour hand, and mobilize students' various sensory organs to participate in learning.
3. Showing small exercises after teaching clock face knowledge can consolidate new knowledge in time.
Third, know the whole time.
1, Teacher: Hey, listen, what's that noise? It turns out that the alarm clock of lazy sheep's house has rung, so I have to get up and go to Big Fat Sheep School! We should also go to bed early and get up early every day, and don't be lazy.
Teacher: What time is it?
Health: 7 o'clock.
Teacher: We should say that 7 o'clock is our spoken language in standard language, and we should say 7 o'clock.
Teacher: How did you recognize it?
The minute hand points to 12 and the hour hand points to 7.
2. Teacher: (Showing courseware) A flock of sheep are taking a lunch break. What time is it now?
Health: 1 hour. (Display clock)
Teacher: How did you recognize it?
The minute hand points to 12 and the hour hand points to 1.
Teacher: (showing courseware) After a day's study, the lambs are out of school. What time is it now?
Health: 4 o'clock. (Display clock)
Teacher: How did you recognize it?
The minute hand points to 12 and the hour hand points to 4.
4. Teacher: (The courseware reproduces 7 points, 1 point, 4 points). What are the similarities between these three clocks?
Health: The minute hands all point to 12. Introduce the way you think of to know the hour. group discussion
Health: The minute hand points to 12, and the hour hand points to several hours.
Teacher: The clever monitor Jonie told us: "The minute hand points to 12, and the hour hand points to what time." .
5. Teacher: Now Jonie will test whether we can look at the clock face. Let's have a look!
(Show the courseware), look at the clock face and tell the time.
Born in 1: 6, 2: 9, 3: 8, and 1, the cartoon character "lazy sheep" was introduced to the school, and the life of sheep in the school runs through the teaching, which is full of fun.
2. Jonie, the monitor of cartoon characters, is clever and kind, and it is very helpful to summarize the whole time with vivid cartoon characters.
Fourth, write the whole teaching time in two ways.
1, Teacher: Students, now let's look at these three clocks on the blackboard. Everyone can tell the time. Can you write it down?
Health 1: Yes
Teacher: OK, now please listen to Pleasant Goat and tell us how to write "7 o'clock". (Teacher demonstrates blackboard writing)
Teacher: Who can write the following two clocks?
Student 1: Play on the blackboard.
The teacher concluded: This representation is called literal representation. Just add the word "when" after the word "when".
2. Teacher: There is another expression (courseware shows electronic clock). What is this?
Student: Electronic watch.
Teacher: We call this method of recording time like an electronic watch digital representation.
Teacher: Who will write 1 and 4 o'clock?
Student: Play on the blackboard.
Teacher's summary: (Showing courseware) Monitor Jonie told us that when the whole hour is expressed by numbers, there are two "0s" on the right side of the colon, and what hour is on the left side of the colon. (Students follow)
(emphasize that two points cannot be written as periods)
3. Teacher: Can you write down the time of three clocks on the blackboard in figures?
Teacher: Let's play a little game "Pleasant Goat vs Big Big Big Wolf". Big Wolf said, If Pleasant Goat answers wrong, eat it and see if it can help Pleasant Goat, OK?
The exercises are relatively simple, and the exercises are designed step by step, so that the middle and lower classes have the opportunity to play and experience the joy of success.
Verb (abbreviation for verb) consolidation exercise
1, Teacher: With the help of classmates, Pleasant Goat finally defeated Big Wolf and escaped the fate of being eaten. Big Wolf was not convinced, so he asked the teacher to test everyone again to see if the students had learned the content of this lesson.
2. Exercise 1: The teacher dials and the students say (2 o'clock, 5 o'clock, 12 o'clock).
3. Exercise 2: When student A dials an integer, student B says it.
4. Exercise 3: Write and write the time in two ways.
5. Exercise 4: Draw a picture (showing the clock face and time). Students draw minute or hour hands.
Correct the answer with projection
Abstract of intransitive verbs
Sleepy lazy sheep tells our classmates that time is precious. We spent 40 minutes learning how to look at the clock. There are two ways to show the time. For us, time is knowledge. I hope that students will make good use of time, cherish time and be the little masters of time in the future.
1, deepen students' understanding, consolidate learning content, and let students understand and internalize knowledge in practical operation through rich exercises such as teachers' teaching, students' teaching, writing and drawing, so as to complete cognitive construction.
2. Educate students through the words of cartoon characters-time is precious, and educate students to cherish time and be the little master of time. It shows that teachers make good use of teaching resources and carry out moral education thoughts, so as to achieve the purpose of teaching and educating people.
