| Outline of Final Research Achievements |
Two categories of concepts, triangles and quadrilaterals, and fractions, are analyzed respectively, with focusing mainly on students' misconceptions, manipulatives and drawnings. The verbal explanations of triangles, quadrilaterals, and fractions are written in mathematics textbooks, however, these do not function as the criteria of mathematical decisions students make. Then adequate drawings and manipulatives are needed to support students' suitable understanding of concepts and ideas. For example, learning of mixed numbers, positioning of fractions on a number line can prompt adequate understanding of fractions. This suggests that the well-suited drawings can make students understand the meaning and significance of mathematical concepts and ideas.
