Free Flat or Solid Shapes Worksheets for Kindergarten – 2D vs 3D Shapes

These free printable flat or solid worksheets help kindergarten and first grade children tell flat shapes and solid shapes apart. Flat shapes, like a circle or a triangle, are drawn on paper and have no thickness. Solid shapes, like a ball or a box, take up real space and can be picked up. On each row kids look at a shape and circle whether it is flat or solid. This builds on learning flat shapes and solid shapes separately, and helps children sort the shapes they see every day into the two groups. The final page is an answer key. Just download, print, and sort!
