Teaching content: PEP Edition “compulsory education curriculum standard experimental textbook · Mathematics” third grade volumes on the first 92 ~ 93 pages. Teaching Objectives: 1. Combination of specific situations, so that students initially understand the meaning of the score, recognize a fraction of the score. 2. In the teaching process to develop students’ observation skills, hands-on ability and language skills. 3. Through the observation, operation, comparison and other mathematical activities, to develop the courage to explore the spirit of students so that students get a successful experience. 4 to make students feel the score is generated from the actual needs of life, feel the connection between mathematics and life, to further generate curiosity and interest in mathematics. Teaching points: understanding the meaning of the score, to know a fraction. Teaching Difficulties: Comparison of molecules is a fraction of the size.
