教学目标与重点上面让学生联系分数的意义,初步掌握用分数表示具体情境中简单事件发生的可能性的方法,会用分数表示可能性的大小,进一步加深对可能性大小的认识。使学生在用分数表示可能性大小的过程中,进一步体会数学知识间的内在联系感受数学思考的严谨性和数学学习的趣味性。进而体验数学的实用性,提高学好数学的信心。
Teaching Objectives and Emphasis The purpose of getting students to associate points is to gain an early understanding of the ways in which points are used to indicate the likelihood of a simple event in a particular situation. Points are used to indicate the likelihood of the event, further deepening the understanding of the likelihood. Enable students to score the possibility of the size of the process, to further understand the inherent relationship between mathematical knowledge experience the rigor of mathematical thinking and mathematical learning fun. And then to experience the practicality of mathematics and improve the confidence of learning mathematics.
