Third, we evaluated differences in accuracy according to which CCSS domain each vocabulary term was associated. Differences between vocabulary terms within the same domain were also examined. For example, within Geometry terms, stu- dents correctly identified 51.3% of plane figures and 56.9% of solid figures. More than 70% of students correctly identified the plane figures circle, rectangle, rhombus, square, and triangle, and more than 60% of students recognized cone, cube, and sphere.
