The viewpoint of this research is the teaching of calculation that raises the awareness of relative to the number.We have developed teaching materials to spread the idea of Complement Number by the ways of addition of two one-digit numbers and subtraction as the inverse operation.We verified the effect from the actual lessons. The idea of Complement Number improves the the efficiency and certainty.The idea of Complement Number has a cultivated value, a practical value and a systematic value.To be specific, We have decided to teach the Unit Number of 20 and the Unit Number of 100.We was the development of the number models. When carrying out the verification lessons, more than 90% of all children had been able to understand. However, it was found to be difficult to spread the idea of Complement Number. In addition, it was found that the ways of the Unit Number of 10 and the ways of the Unit Number of 100 were needed teaching same as seen. |
