First, the teaching objectives (A) knowledge and skills Objectives 1. To understand the historical background of the number of Pythagorean polygons 2. Experience the mathematical thinking of Pythagorean polygons 3. Use the existing knowledge to generalize the law, Reasoning (2) Process and Method Objectives Fully give students the opportunity to independently explore and cooperate in communication so that students experience thinking processes such as intuition, observation and discovery, abstract summarization, and inductive reasoning, and make them realize the important significance of combining figures and figures (3) Modality, Attitude and Values Aims Learn the contribution of ancient mathematicians to mathematics through the study of the number of polygons of Pythagoras, fully understand the long history of mathematics and culture, and further stimulate
