What mathematical term corresponds with the developmental vocabulary 'shapes'?

The term that corresponds with the developmental vocabulary 'shapes' is "Figures." In a mathematical context, "figures" is a broad term that encompasses various types of shapes, including polygons, curves, and three-dimensional objects. The term "figures" is commonly used in educational settings to refer to any form of geometric representation, making it more inclusive and aligned with the concept of 'shapes' that children are learning to identify and describe.

While "polygons" is a specific type of shape characterized by straight edges and vertices, it does not encompass all types of shapes, such as circles or other variations that may be introduced to young learners. The other options, "curves" and "objects," similarly refer to specific types or categories of shapes but do not capture the full range of what 'shapes' can entail in a developmental vocabulary context. Therefore, "figures" serves as the most appropriate term to represent the broader understanding of shapes in mathematical learning.
