Activity objectives:
1, learn the ordinal number of 1-5, and initially understand the meaning of ordinal number.
2. Ordinal numbers will be used to indicate the arrangement order of objects and establish a one-dimensional spatial position correspondence.
3. Develop children's observation and spatial imagination.
4. Let the children judge the quantity correctly.
Activity preparation:
1. A picture of a small animal (monkey, fox, panda, giraffe, elephant).
2. A small train with five carriages (painted on the blackboard.
3. Children's books and teaching wall charts.
Activity flow:
First, the concept of ordinal number is naturally derived from stories.
1, story import:
There is a small train in the animal kingdom, and the small animals decide to go to Beijing to play by train. The teacher showed a schematic diagram of a small train consisting of five carriages. Let the children count how many cars there are in the small train (1, 2, 3, 4, 5, * * * has five cars). Let's mark these cars with the mathematical treasures in the digital kingdom! (Guide the children to stick the digital baby on the carriage. )
2. Teacher identification number card:
Teacher: How do we mark these numbers? Let's find the locomotive first and number it from the side of the locomotive. )
3, the teacher said while demonstrating:
Here is the first section. We use the number 1 and put the number 1 on it. In the second part here, we use the number 2 and put the number 2 on it. ...
The teacher asked the children to count and said, "Section 1, Section 2, Section 3, Section 4, Section 5".
Teacher's summary:
"The first section, the second section ..." What we just said is the ordinal number in mathematics.
4, the teacher asked:
What small animals are going to travel? The teacher takes out pictures of animals, demonstrates and explains them, and puts the corresponding animals in the corresponding carriages. The little monkey sits in the first carriage, the little fox in the second carriage, the panda in the third carriage, the giraffe in the fourth carriage and the elephant in the fifth carriage.
Second, understand the concept of ordinal number and verbally express who is in which car.
1. The train has been driving for a long time, so we stopped to let the passengers off and have a rest. All the animals came down.
When the train was about to leave, the panda was in a hurry, because she couldn't find her own carriage and couldn't remember which carriage she was sitting in.
Who wants to help him? How can we help him? Tell him which car it is, or take him directly. )
Please tell the children who is in which car.
Third, through the operation, try to correspond the ordinal number with the spatial position.
Please put the pictures of small animals in the corresponding spaces of the train and practice the corresponding relationship between ordinal number and spatial position.
Fourth, open the children's book, or look at the wall chart and complete the operation exercise.
1, * * * How many small animals are playing on the slide? Where are they ranked?
Please tick the corresponding box behind each small animal.

Mathematics can create the best scene for children to start work, talk, think and all kinds of senses to participate in learning activities, stimulate children's interest in learning, arouse students' enthusiasm, maximize students' physical and mental potential, save time, complete learning tasks efficiently, infiltrate ideological and moral education, cultivate good learning habits and psychological quality, and make intellectual quality and non-intellectual quality develop harmoniously. Guide students to "play" middle school, practice in "fun", increase their talents in "fun" and increase their courage in "competition". Improve learning efficiency and cultivate students' good study habits and organizational discipline.
