| Popis: | 105 Study of the Padagogy for the Addition and Substraction of Fraction Fraction is a mathematical concept which is widely used in daily life. It’s importance is surpassed by only the concept of integer. The concept of fraction plays an significant role in mathematics learning. The purpose of this study is to explore the addition and subtraction of fraction in teaching materials of elementary school. This study introduces the situations which fractional numbers are needed to be used. With the diagrams, the concept will be shown more clearly. After the preliminary introduction of fraction, the addition and subtraction of fraction will be explored. The author makes an effort to understand why students make mistakes on learning fraction. By doing this, the more profound understanding of fraction learning can be persuaded. The author also makes a research on the addition and subtraction of fraction through the purring water questions. Fraction learning is an important sector in elementary mathematics, it is taught from the third grade to the fifth grade. Students spend a long time building the concepts and mastering the operations of addition, subtraction, multiplication and division. And thus they obtain correct concepts. The study also helps teachers acquire more accurate concepts. They have a more systematic teaching. And students grasp the relative informations more easily while learning fraction. |
