Activity objectives:
1. I like to participate in the game activities of sending letters and am willing to help others.
2, master the ordinal number within 6, and can correctly number the mailbox in sequence.
3. Have preliminary sorting ability, and try to cooperate with peers to complete the task.
Activity preparation:
1. Material preparation: six new houses for small animals, mailboxes corresponding to the six houses, and a letter with an address mark for each person (in which grandma rabbit is sick in the letter and a birthday cake is drawn in the letter of bird).
2, children's knowledge and experience preparation: learning the ordinal number within 6, knowing which floor the new home of the small animal lives on, will distinguish the up and down direction.
Activity flow:
Show "architecture" first, and introduce the topic of delivering letters in a game tone.
1, the teacher asks questions.
(1) Let's take a look at the new home that we helped the animals move last time. Please tell us who your favorite little animal is. Where does it live? (2) Please guess who the small animal lives in "which building and which floor". Focus: Help children review which building and which floor the new home of the small animal is in.
2. Put forward the task: Show me a letter, where should I send it?
(1) Please take a closer look at the above addresses: 2 and 5. The teacher helps the children understand that this refers to the fifth floor of Building 2, and find the corresponding mailbox in the mailbox. (2) Question: How to make it easier for the postman to deliver letters? Mark the mailbox with numbers according to the address.
Second, guide the children to say the email number of the new home of the small animal and master the ordinal number within 6.
1, ordinal number in exercise 6.
(1) Counting floors: Practice the bottom-up sorting method and learn which floor. The teacher used a digital card to paste the image. (2) Counting floors: Practice the method from left to right and say "which building".
2. Show the envelope and understand which building the front number represents and which floor the back number represents, such as 4-3 (the third floor of Building 4).
The teacher asked the children to work in groups and numbered each mailbox.
Third, the game "send a letter": the children press the address on the envelope and send the letter to the mailbox of the small animal. Everyone has a letter, please send it to the email address.
Characteristics of ordinal number
1, ordinal number is an integer. Because every element in the collection can be sorted, the ordinal number must be an integer.
2. Ordinal numbers are limited. Because the number of elements in a set is limited, the ordinal number must also be limited.
3. Ordinal numbers are continuous. Each element has a clear position in the sorting, so there is a clear order relationship between them.
