Kindergarten · Geometry
2D Shapes and 3D Objects
Shapes are the language of space. Before students can navigate geometry, they must be fluent in the shapes that tile the world around them. But in Kindergarten, the goal is not to name shapes — it is to describe them by their attributes (sides, corners, curves). A square is interesting not because it is called a square but because all four sides are equal and all four corners are the same. Noticing these properties is geometric thinking.
