Activity objectives:

1. Learn how to count objects in a closed arrangement to improve children's counting ability.

2. You can mark the starting point in various ways, count independently and record the results.

3. Experience the fun of counting in different ways.

Activity preparation:

1, children's book mathematics;

2. A photo of a little monkey in a circle and a big record sheet;

3. The number of strokes is equal to that of sub-strokes; Small stickers, plasticine in the basket.

Activity flow:

First, children play "Walking in a Circle" and learn to count objects in a closed arrangement.

Teacher: The teacher wants to invite the children to play the game of "walking in a circle", and ask them to come up and pull in a circle and walk in the same direction.

1, please 10 Children join hands to form a circle and play the game of "Walking in a Circle".

2. How many children are guiding their children to count mobile games in their own way?

Teacher: How many children are playing games here? Count gently, raise your hand and tell me immediately after counting!

3. Let the children try to count in their own way: How many children are there? How do you remember where to start counting?

Ask a child to come up and demonstrate counting: who should I start counting? And then who will be finished? So who is the starting point? What is the starting point? How do you remember the starting point?

4, the teacher summed up according to the children's method: Originally, counting from the starting point to the end point next to the starting point can be counted clearly.

Second, count monkeys and learn to mark the starting point in various ways.

1, put the little monkeys in a circle to show PPT: Look, who's in the middle? Naughty little monkeys learn to play in circles, and the mother monkey can't count how many little monkeys there are. What can we do to help the mother monkey count how many little monkeys there are? What good idea have you come up with? There are many materials in the basket on the table to mark, so you can choose what you like to try later.

2. Children use "Naughty Little Monkeys" on page 16 of Children's Book Mathematics: Please mark the starting point in your own way, and then count how many little monkeys there are. Circle the corresponding numbers on the tree.

3. Experience sharing: Please introduce your own methods. What method did you use? How many little monkeys are there? Is there a different way?

Ask individual children to say their own methods, and the teacher will record them on the form according to the methods said by the children.

Summary: There are so many ways to mark and count monkeys clearly.

Third, children practice the counting method of closed arrangement and record it.

1, derivative operation

Teacher: We have learned how to count objects in a circle. Now we use this method to help the little monkey count the patterns on some objects in his house.

2, put forward the operation requirements

Teacher: Count the number of patterns arranged on each item in the picture, and then record the answers in () under the item with dots. Children who can write numbers can record directly with numbers.

3, children's operation, teachers tour guidance, teachers focus on guiding individual children with weak ability, and help them master the method of closed arrangement and counting in further guidance.

4. AC counting method.

Teacher: After finishing, the children can introduce their own methods to each other and see if the results calculated by your methods are all the same.

Fourth, the conclusion is over:

Today, we learned to count the items arranged in a circle by using the starting point mark method. After the children go home, they can continue to look for and count, and become a little expert in counting.
