Once I was in the class of (neighbor number of 1-5), a child puzzled and asked, "Teacher, what does neighbor number mean?" Facing this confused face. I started to meditate. Yes! How can I tell my children clearly and vividly? So I changed the way I used to attend classes and designed a new teaching activity. First of all, show some children's favorite animals in front of them and let them take the initiative to participate in this game (helping animals live in new homes). Secondly, let children understand the meaning of adjacent numbers through various games. Children learn while playing, and cultivate their comparative analysis ability, hands-on operation ability and simple reasoning ability.
moving target
1, learn the adjacent numbers within 5, and let the children know that the adjacent numbers of 2, 3 and 4 are 1 and 3, 2 and 4, 3 and 5.
2. Understand the simple relationship between adjacent numbers and apply it to real life.
3. Cultivate children's concentration, imagination and operational ability, and improve children's initiative to participate in and explore mathematical activities.
Teaching emphases and difficulties
1, understand the meaning of adjacent numbers.
2. Understand the law of neighbors: the median is one more than the previous digit and one less than the last digit.
Activities to be prepared
House color map card, small animal headdress, small round paper.
Activity process
First, praise the children's love of brains with small guests, create a pleasant atmosphere, and mobilize the enthusiasm of children to participate in the "Walking into a New Home" activity. Understand the meaning of perceiving proximity.
1, Teacher: Today, several children's favorite guests came to our class to help children learn new skills. Do we want to learn new skills?
Show animal headgear: chicken, duckling, kitten, rabbit, fox. )
2. Teacher: With so many guests here, who wants to be a housekeeper and help them arrange rooms?
Show the house, stick it on the blackboard in order, and let the children live small animals in their new home. )
Second, make use of the small animal house to guide children to know the neighbor number of 1-5.
1, Teacher: What room do animals live in? Who lives next door to them? The teacher asked the children to observe the animal's new home, find out the house number and write it down, and then carefully observe who lives next door to whom. )
The teacher concluded: They live together, so we call them neighbors.
2. Teacher: Who are the neighbors of the kitten, chicken and fox? What is the neighbor's house number? The teacher asked the children to observe the neighbors and house numbers of animals. )
4. Teacher's summary: We call the numbers of the houses that live together in this order the adjacent numbers.
Third, music games. Teacher: The children are really capable of arranging such a good room for their guests and helping them find out who their neighbors are. The teacher is really happy. The teacher wants to use music to express the number 1-5 with the children, ok? Children learn to sing under the teacher's demonstration, and their learning atmosphere can be adjusted through music games. )
Fourth, children operate stickers and feel the neighborhood rule. The teacher is working with the children to find out the number of neighbors of kittens, chickens and foxes. 1, Teacher: Here are some small round pieces of paper. Who would like to help the teacher put the following numbers on the paper? )
