Math Kindergarten Quiz Identify shapes as two-dimensional (lying in a plane, “flat”) or three-dimensional (“solid”)-K.G.A.3

CCSS.MATH.CONTENT.K.G.A.3 In this standard, students are expected to differentiate between two-dimensional (2D) and three-dimensional (3D) shapes. Two-dimensional shapes are flat and lie in a plane, like a drawing on a piece of paper. Examples include squares, circles, and triangles. Three-dimensional shapes, on the other hand, are solid and have depth, such as cubes, spheres, and cones. Recognizing the difference between these types of shapes helps students better understand the world around them and lays the foundation for more advanced geometry concepts.
