Core accomplishment is the essential character and key ability that students should have to adapt to the needs of lifelong development and social development. Since the reform and opening up in China, the curriculum objectives have undergone three important changes, from the "double-base" curriculum objectives that emphasize basic knowledge and basic skills, to the "three-dimensional goals" that emphasize knowledge and ability, process and method, and emotional attitude values, to the curriculum reform based on core literacy. Each reform reflects China's reflection on the reform of basic education and the consideration on what kind of talents to cultivate. However, the current situation of education is still in the transitional stage from knowledge imparting to ability cultivation. It is important to develop students' core literacy and give full play to the function of discipline education, which points out the direction for the reform of the mathematics curriculum in China. It is necessary to clarify the background of curriculum reform and the connotation of mathematics core accomplishment, and discuss the strategy of mathematics curriculum reform and the change of teaching mode under the guidance of core accomplishment, so as to make beneficial exploration and important supplement for China's mathematics teaching reform.
