Advantages:

1. The thinking is clear, the mathematical language is concise and infectious, which embodies the requirements of student-oriented education and the teaching effect is very good. Teachers have done a lot of preparatory work and prepared lessons carefully. Make full use of courseware to show students how to make up ten directly.

2. Add a few carry addition, students think of many methods, and teachers can focus on guidance, especially teachers who explain the ten-point method in detail, and teach by watching, speaking, swinging and circling.

3. Create life situations and lead to mathematical problems. The teacher combined the age characteristics and psychological characteristics of the first-grade primary school students to create the teaching situation of the sports meeting. Let the students observe the scene map of the sports meeting, find out the mathematical information and ask the mathematical questions. This arrangement not only communicates the connection between mathematics and life, but also cultivates children's ability to look at pictures to get information and ask questions.

4. Use a variety of methods to break through teaching difficulties. "Making up ten" is the key and difficult point of this lesson. The teacher has been paying attention to the knowledge point of "make up ten" from the introduction exercise before class to the explanation of the newly given example calculation method.

Especially when solving the problem that * * * * has several footballs, students can clearly see the dynamic demonstration process of "filling ten" through the combination diagram. With the help of multimedia technology, turning static into dynamic, turning difficult into easy, let students understand the algorithm of rounding ten intuitively and vividly, and solve the original difficult teaching difficulties.

Shortcomings and suggestions:

1. After students study the "Ten-Point Method" in groups, they can use their own learning tools to demonstrate it to the whole class with slides, which is more conducive to the understanding and application of the "Ten-Point Method". It's much better than what students just say with their mouths.

2. Students' cooperative learning time is short, so children should be given enough learning time to make group learning effective, let them share their own small algorithms, and let every child have a chance to speak.
