"Understanding Single and Double Numbers" in Mathematics Activities of Large Classes
Design intent
First, in order to let children distinguish and understand the odd and even numbers within 10 in a relaxed and pleasant atmosphere, I introduce the game scene of finding friends.
Second, use PPt operation to let children know a group of objects. If there are two numbers, the last count is a double number, and the last count is a singular number.
Third, let children know the difference between odd numbers and even numbers within 10 by looking for perception, using school tools to operate independently and playing games.
moving target
1, use visual teaching AIDS to guide children to understand the concept of odd and even numbers, and let children understand odd and even numbers within 10 in game activities.
2. Understand the relationship between odd and even numbers.
3. Develop the flexibility of children's thinking.
Teaching emphases and difficulties
Teaching emphasis; Know odd and even numbers within 10
Teaching difficulties; Understand the meaning of singular and even numbers
Activities to be prepared
1. Put some items in pairs in the classroom.
2. Small animals, Diandian and digital baby have one home, Diandian 1- 10 has one card and several digital cards.
Activity process
1, find friends to import the game. Teacher: Little friends, do you like playing games? Let's play the game of finding friends, shall we? Through the game of finding friends, we know that the number of people who find friends is even and the number of people who can't find friends is odd.
2. Introduce the concept of odd and even numbers, and use visual teaching AIDS to guide children to know the skills of distinguishing odd and even numbers.
A, Teacher: Many small animals want to play games today. Let's see who they are. Little monkey. Teacher: How many little monkeys are there? Young: 4. Teacher: That can be represented by the number 4. Teacher: How many chickens are there? Young: 5. Teacher: That can be represented by the number 5. Teacher: How many little blackbirds are flying in the sky now? Young: 6. Teacher: How many numbers can that represent? 6, so who is singular? Who is the even number? Let's see, monkeys can circle in pairs here, and even numbers can find good friends. After two chickens are kept together, one more chicken can't find friends.
Teacher: Small animals have come to join our game. What small animals are there? Strange beasts seek strange homes, and even beasts seek my home. The teacher stepped forward to operate.
B. Teacher's summary: We both found a home, looking for friends and animals.
C, Teacher: Little Dot has come to our game, please help them find their own home.
Ask a child to operate forward.
D, Digital Baby also wants to join our game. Would you please take the digital baby home?
Let the children take the digital baby home.
3. Understand the meaning of odd and even numbers through children's practical operation.
A, Teacher: Children, each of you has a baby card next to your chair. Listen with your little ears. Come on, come on, take out the odd numbers. Listen and take out the cards. Teacher:
Quick, quick, please find the even number one, so that children can understand the meaning of even and even numbers again.
4. Guide children to practice.
Teacher: Today, we have some new games waiting for you. The new games are all behind. Please operate them in an orderly manner.
Children's group operation, teachers tour guidance.
5. Summarize the skills learned above to distinguish between odd and even numbers, and further consolidate how to distinguish between odd and even numbers.
Teacher: Now the teacher shows the children the last game. Ask the child to move forward. Children will guide them in front of the machine and tick the odd and even numbers.
Teacher: Children know even numbers and odd numbers, and they can also express them with our songs, right? Come on, let's sing! End the activity with a song.
