This medium worksheet keeps kindergartners busy as shape detectives. Part A delivers nine fill-in-the-blank prompts about rectangles (4 corners, 2 long sides), circles (0 corners), triangles (3 corners), squares (4 corners), hexagons (6 corners), and ovals—the stretched circle. A couple of clever blanks ask kids to name 'a shape with 3 sides' (triangle) and 'a shape with 6 sides' (hexagon).

Part B closes with a four-pair matching set linking rectangle to '4 corners,' oval to '0 corners,' triangle to '3 corners,' and square to '4 equal sides.' This mix of recall and matching strengthens the side-versus-corner habit kindergartners need for first-grade geometry.
