Activity goal: 1, know the neighbors within 5, and find out the neighbors with each number within 5.
2. Be able to understand the operation requirements and carry out the operation activities seriously.
3. Concentrate on activities and be able to answer the teacher's questions loudly.
Activity preparation: experience preparation: children know the numbers within 5, perceive the numbers within 5, and know what neighbors are.
Material preparation:
Teaching aid: five drop-shaped digital cards (the numbers are 1-5) and a picture (with five identical houses painted on it, lined up together). Houses are written with the numbers 1-5 respectively)
-school tools: "children's books", children have pens. Some digital seals and inkpad of 1-5.
Activity flow:
First, the game: digital solitaire.
Teacher: Let's play a game of "digital solitaire". I say a number, then you say a number.
Teachers and children play the same game. The teacher said 1, the child said 2, and so on.
Second, find neighbors.
Teacher (number plate showing the shape of water droplets): It's raining, and five small raindrops are falling from the sky in a row. Let's get to know them.
-The teacher showed the picture of the house and asked individual children to send the water drop counting cards to the house according to the numbers, and said: 1 Water drop lives in room 1. ...
Teacher: Xiao Shuidi wants to play with his neighbors. Who are the neighbors of No.2 water drop? 1 1 Is it more than 2 or less than 1? Does water drop 2 have any other neighbors? How about 3 to 2? ...
Third, the game: see who speaks fast.
Fourth, the teacher gave the numbers and asked the children to name one of their neighbors. For example, Teachers' Newspaper 3 and Children's Newspaper 4, and explain why 3 is 1 less than 4.
Five, children's operation activities.
-Fill in the numbers. Let the children observe the numbers and ideas on the pigeons, and print the corresponding numbers or draw dots in the blanks.
-Looking for neighbors. Observe the number of frogs in the picture above, find out the neighbors in the picture below and connect them. This activity, the whole teaching process is a game. Children learn and master knowledge in the process of playing. I found that they master the knowledge learned in this class very well through after-class observation. Although some children can't blurt out the neighbor number of a certain number because of individual differences, they will definitely tell the learning process of that lesson and then find out the answer slowly.
Activity reflection:
The focus of this lesson should be to learn to find adjacent numbers first, and then to understand the relationship between adjacent numbers, so that children will be more acceptable. But how to introduce the concept of adjacent number? I use the word "beside", which is easy for children to understand, to introduce adjacent numbers to children. First, please ask five children to stand in a row in front of everyone with digital headdresses, and then ask the following children to tell who the five digital babies are next to them and point them out one by one. Children can say digital baby 1 next to digital baby 2, and digital baby 2 next to 1 and "3" ... Although there is no number "6" on the stage, children can say that 5 is next to "4".
