Flat or solid worksheets
A square is flat and a cube is solid, and telling the two apart is the first sorting a child does in geometry. These free printable worksheets draw one figure per row and ask for one of two words.
If they get stuck

The answer key prints on a separate page.
What's on this sheet
Two words, not four. Flat or solid is a yes-or-no question and dressing it up as a longer list would only test reading — a kindergartner who knows a cone is solid should be able to say so without picking their way through six names they have not met yet.
Why this sheet works
The four solids are the four the standard itself names: cube, cone, cylinder and sphere. A triangular prism belongs to a later year, and putting one here would be asking a different grade's question in a kindergarten row.
