1 Class angle and intersection line
Test requirements 1, can compare the size of angles, can estimate the size of an angle, can calculate the sum and difference of angles, and can carry out simple conversion.
2. Understand and master the angular bisector and its properties.
3. Understand and master the meaning of complementary angle, complementary angle and vertex angle, calculate the complementary angle and complementary angle of an angle, and know that the complementary angle of an equal angle is equal, the complementary angle of an equal angle is equal and the vertex angle is equal, and use it for simple calculation.
In the review process of teaching and learning, students are the main body and teachers are the assistants. The suggestions are as follows:
1, the knowledge points are told by the students first, and then the teacher strings the knowledge points in this section;
2. After the students finish the exercises, they can dictate the thinking process and answers. Because the calculation of the angle and the bisector of the angle are the key and difficult points in the review content of this section, students must write the answers to related exercises, and teachers should also have some blackboard demonstrations.
Teaching process arrangement
Review the flow chart, review the content and purpose
Activity 1 Exam has clear exam requirements for related knowledge points.
Activity 2 Knowledge points and method knowledge points explain and review the corresponding examples, get familiar with the knowledge points and skillfully solve problems.
Activity 3 Classroom practice Consolidate exercises and break through review difficulties.
Activity 4 Knowledge Quiz Quiz to see if the knowledge points pass the test.
Activity 5 Consolidate homework and cycle exercises after class.
