This challenging worksheet asks second graders to compare 2D and 3D shapes side by side. Part A multiple choice covers which polygon has the most sides among pentagon, hexagon, and triangle, how many faces a square pyramid has in all (5), and which 3D shape has 2 flat circular faces and 0 vertices (cylinder). Part B fills in deeper relationships: a hexagon has 3 more sides than a triangle, both a cube and a rectangular prism have 6 faces, and a square pyramid has 5 faces, 8 edges, and 5 vertices. Strong attribute reasoning builds the foundation for classifying quadrilaterals in third grade.
