【Abstract】 The main purpose of the present study is to design a rating scale of number sense for high graders in elementary school. Based on previous theoretical framework and current primary mathematics textbook,the first edition of the scale was complied. It was tested on 575 primary school children in grade six. The results showed that:(1) "Number Sense Rating Scale for High Grader" included five components:Understanding numbers meanings and relationship,applying number and comparing magnitude in real context,representing numbers in various means,developing the computational strategies and judging the reasonableness. (2) The scale showed good psychometric properties and can be used to evaluate the status of number sense for primary school children.更多还原
