Understand the activity goal of 1 in the teaching plan of large classes with even and odd numbers within 10;
1, through the creation of situations and gamification teaching, let children understand and distinguish between single and even numbers within 10 in operation;
2. Cultivate children's ability to find even and odd numbers from things around them;
3. Stimulate children's interest in odd and even numbers and actively participate in math activities.
Activity preparation:
2 yuan supermarket scene, 1- 10 coupon, one red marker per person, children's group operation information.
Activity flow:
First, the scene import, stimulate interest
Look! We came to 2 yuan Supermarket. Please guess, why is it called 2 yuan Supermarket?
Second, experience and perceive odd and even numbers in shopping games.
1, the teacher explained the rules of the game.
Count, how much do you have? How many things can I buy in one lap?
Children play shopping games to remind them to be civilized customers.
Third, understand odd and even numbers in communication and comparison.
1, discussion: How much do you have? How many things did you buy? Do you have a lot of money?
2, recycling coupons: children with one yuan left will send coupons to one side, and all used ones will be sent to the other side.
3, collective investigation, solve the problem: "1" which side should be sent?
4. Teacher's summary:
(1) Like 1, 3, 5, 7, 9, there is always an odd number left; 2, 4, 6, 8, 10 can all add up to two numbers, which are called even numbers.
② There are five odd numbers and five even numbers within10.
Odd numbers are next to even numbers and even numbers are next to odd numbers. They are all good friends holding hands.
Fourth, distinguish between odd and even numbers in games and operations.
1, find the odd and even numbers around you.
2. Grouping operation
Prepare 4 sets of operation materials, and children can choose the operation freely.
Round and round: two circles, which distinguish between odd and even numbers.
Divide one point: distinguish single and double numbers among many point cards and map cards.
Turn: Turn the turntable, and when the turntable stops, record whether the number pointed by the pointer is odd or even.
Roll the dice: roll the dice, record the odd number of the sequence, and write down its two adjacent numbers.
3. Team games
Hug: singular-hug yourself; Even number.-find a friend to hug.
Understand the design intention of teaching plan 2 for large classes with even and odd numbers within 10.
The math activity "Knowing Even Numbers within Ten" was selected from the textbook of the big class last semester. Singular and even numbers are new knowledge for children in large classes. How to integrate boring math activities into children's lives and stimulate children's interest in math activities is the main goal of math activities. So I will let teachers and children, children and children, children and materials communicate with each other through games, and guide children to learn even numbers and even numbers.
moving target
1, learn to distinguish between odd and even numbers within 10.
2. Experience the fun of mathematics and fall in love with mathematical activities.
Important and difficult
Emphasis and difficulty: identify and distinguish odd numbers and even numbers within 10.
Activities to be prepared
1, management materials: each person 10 ice cream stick.
2. Each person has a record card.
3.55 small sandbags.
Activity process
First, teachers and children say hello to each other.
Second, imports:
Teacher: In the forest kingdom, King Tiger wanted to build a new palace, so King Tiger hired a construction team. King Tiger told the architect, "My palace needs 65,438+00 rooms, and each room is bigger than the other." The architect thought for a moment and said, "No problem, Tiger King, it's my treat." As a result, architects began to carry the most important material for building houses-wood. Children, do you want to be the architects of the new palace of Tiger King? Let's build a new palace together.
Third, children will distribute "wood"-ice cream sticks.
1. Children operate desktop materials.
Teacher: The first room needs 1 piece of wood, and each piece in the back is one more piece of wood than the previous one. But each architect can take two pieces of wood at a time, and make a record in the wood collection. Now, please manipulate the materials on your desk and take notes. You can mark these two pieces of wood as circles instead of triangles and record them on your record card.
2. Discuss and share the record form.
Teacher: Excuse me, which rooms are marked with circles?
Health: 2, 4, 6, 8, 10.
Teacher: Excuse me, which rooms are marked with triangles?
Health: 1, 3, 5, 7, 9.
Teacher: We call even numbers marked with circles, which can be put together in pairs and have no remainder. Numbers marked with triangles, two of which add up to a remainder, are called singular numbers. Let's talk about it together What is an even number? What is singular?
Student: Even numbers are 2, 4, 6, 8, 10, and odd numbers are 1, 3, 5, 7, 9.
Fourth, the teacher summary:
Even numbers are numbers that can be connected together without a remainder, such as 2, 4, 6, 8, 10, and odd numbers are numbers that are connected together with a remainder, such as 1, 3, 5, 7, 9.
Activity extension: Ask children to find out the odd and even numbers that are common in life, make records and bring the records back to the kindergarten for exchange and sharing. The teacher put the corresponding materials in the math area, so that the children can distinguish independently.
Activity reflection
This activity is still difficult for large class children to recognize odd and even numbers within 10. Children have the experience of perceiving things in pairs in life, so they quickly find a pair and have a high degree of interest in games. Therefore, children carry out this activity, which is to let them sum up and sort out their experiences in life and let them learn knowledge through games.
