This study aims to examine the possibility of the teaching definition and geometric property of the parabola in mathematics II. In this report, I recommend teaching materials for the parabola and describe the practice of mathematical lessons using such resources. I was able to further students’ understanding about the geometric property of the parabola via numerous mathematical activities. Furthermore, I promoted a variety of viewpoints regarding the parabola by working on a new problem derived from the solution to original problem. However, some difficulties were encountered, including the setting of coordinates when students searched the property of the figure using an equation.
