This medium worksheet drills the parts of shapes children meet every day. Part A's nine fill-in-the-blanks have students explain that a 2D shape is flat like paper, count a cube's 8 vertices and a cylinder's 2 edges, identify a sphere as ball-shaped with 0 faces, and recall a cone's single edge. Part B is a matching grid that pairs triangle, rectangle, circle, and square with '3 sides,' '4 corners,' '0 corners,' and '4 equal sides.' Switching between 'solid shape' for 3D and 'flat' for 2D builds the precise language Grade 1 standards expect.
