superiority

From the introduction of the classroom to the teaching process, from the mastery of teaching materials and harmonious communication with students, from the teacher's conception and implementation of the classroom, we can all see the hard work of the teacher in teaching these contents, and that he is a thoughtful teacher and a teacher with strong practical ability.

His classroom teaching is wonderful in the ordinary, revealing the way of thinking in communication and showing the charm of teachers in evaluation. I really have a feeling that "one class of your teacher is better than three years of teaching".

disadvantaged

When listening to calculation, if you listen to the unit conversion of the last lesson, rather than the calculation problems unrelated to this lesson, you can not only save time, but also consolidate it. Because the master has thoroughly explained the knowledge points, he has repeatedly asked the students why they should answer the reasons. There is not enough practice time in the back, insufficient training time in class and less class hours. If you say the method, you will feel that you have not done it thoroughly enough.

Textbook analysis

The teaching task of this unit is to enable students to initially form the concepts of 1 hectare and 1 square kilometer. Experience their connection with reality and leave a clear impression in your mind;

Combined with the calculation of land area, it is felt that hectares and square kilometers can easily express the size of land by applying the propulsion rate between square meters and hectares and square meters and square kilometers, so as to understand the land area; Sort out all the area units that have been taught successively, organize a new cognitive structure, and rationally apply the area units. The textbook teaches hectares first, and then square kilometers. Because the square kilometer is a larger area unit than the hectare, the establishment of the concept of square kilometer needs the support of the hectare.

Teaching objectives

1, to help students understand the actual meaning of square kilometers and experience the actual size of 1 square kilometers.

2, know the progress rate between square kilometers, square meters, hectares, and can carry out unit conversion.

3. Let students understand the relationship between mathematics and life, which can solve corresponding practical problems and cultivate students' habit of active exploration.

It plays an indispensable role for students to understand mathematical concepts, consolidate what they have learned in class, cultivate their practical ability and use mathematical knowledge to solve practical problems in life. When students face a certain knowledge point, they will encounter some difficulties. As teachers, it is necessary to find a good way for them to learn knowledge. In order to better combine teaching with learning and improve classroom teaching efficiency.
