The learning objectives of this course are as follows:
1, combined with life situation, realize that there are angles everywhere in life and the connection between mathematics and life.
2. Guide students to understand the angle intuitively through activities such as "looking for it", "folding it" and "comparing it".
3. Compare the angles.
4. Cultivate students' observation ability, hands-on operation ability and cooperative learning ability with peers, so that students can succeed.
"Understanding Angle" teaching material analysis:
This lesson is based on students' preliminary understanding of geometric figures such as rectangles, squares and triangles. Teaching materials combine life situations to guide students to gradually abstract angular geometric figures from observing things in life.
This lesson is to learn new knowledge about activities from characters to angles. Through students' practical operation, deepen the understanding of diagonal. Teaching material analysis, a student, is proficient in this part, which will lay a foundation for learning deeper geometry knowledge. The general requirement of the curriculum standard for the graphic part of this textbook is to know the angle, know the names of each part of the angle, and compare the angles.
