Yunlin County Shuidi Elementary School─Understand the calculation and application of the area of circles and sectors

1. I hope that through mathematical understanding of circles and sectors and their applications in life, students can learn about circles, sectors and their constituent elements from these three courses, and use the circles drawn in class to do this course Guide to make it easier for students to enter this unit (the definitions and calculation methods of circles, central angles, and sectors).

2. Discuss common fan shapes in daily life, and use composite aesthetic flower window graphics to allow students to connect the knowledge learned in the course with life, extend it to aesthetic artistic creation, and improve students' ability to change the combination of graphics. There are different understandings and applications of beauty in daily life. By integrating artistic knowledge, cultivating aesthetic literacy, expanding students' learning experience, and implementing students' aesthetic education.
