Primary 2 Mathematics Quiz - Shapes (Answer Key)
Total Marks: 20
Topic: Shapes (2D and 3D, P2 Syllabus)
Q1. (1 mark) Triangle
Teaching note: A triangle is a flat (2D) shape with 3 straight sides and 3 corners (vertices). Count the sides to check.
Q2. (1 mark) Square
Teaching note: A square has 4 equal sides and 4 right-angle corners. A rectangle also has 4 corners but its sides are not all equal.
Q3. (1 mark) 5
Teaching note: The diagram shows a pentagon (labelled A–E). A pentagon has 5 straight sides and 5 corners. Count each side between two labels.
Q4. (1 mark) Circle
Teaching note: A circle is a curved shape with no straight sides and no corners. It is a 2D shape.
Q5. (1 mark) Circle
Teaching note: The red shape in the placeholder has a curved closed line and no corners, so it is a circle, not a square.
Q6. (1 mark) Shape B (rectangle)
Teaching note: Shape B is longer than wide with 4 corners and opposite equal sides — that is a rectangle. Square (A) has equal sides; triangle (C) has 3 sides.
Q7. (1 mark) 3
Teaching note: A triangle always has 3 corners (vertices). This matches the 3 sides.
Q8. (1 mark) Sphere
Teaching note: A sphere is the 3D shape like a ball; it has 1 curved surface and no flat faces.
Q9. (1 mark) Cube
Teaching note: A cube has 6 flat square faces, 12 edges, 8 vertices. A cuboid has rectangular (not all square) faces.
Q10. (1 mark) Cone
Teaching note: A cone has a flat circular base and a pointed top (vertex). It is a 3D shape.
Q11. (1 mark) 6
Teaching note: The cuboid diagram shows a rectangular prism. It has 6 flat rectangular faces (top, bottom, front, back, left, right).
Q12. (1 mark) Sphere
Teaching note: A sphere has only a curved surface so it rolls. A cube has flat faces and slides but does not roll.
Q13. (1 mark) Cylinder
Teaching note: A cylinder has 2 flat circular faces (top and bottom) and 1 curved surface around the side.
Q14. (1 mark) C (cone)
Teaching note: In the diagram, C is the cone: circular base, point at top. A=cube, B=sphere, D=cylinder.
Q15. (1 mark) Circle
Teaching note: Pattern repeats every 2: circle, square. After "circle, square, circle, square" the next is circle.
Q16. (1 mark) Triangle
Teaching note: Pattern is triangle, triangle, square (repeat). After the given 6 items, the 7th is triangle.
Q17. (1 mark) Red

Q18. (1 mark) Big
Teaching note: Size pattern is big, small repeating. After big, small, big, small, the next is big.
Q19. (1 mark) Cube (or cuboid)
Teaching note: A cube or cuboid has flat faces so it can slide on a flat table and does not roll because it has no curved surface.
Q20. (1 mark) Pentagon
Teaching note: Triangle=3 sides, square=4 sides, pentagon=5 sides. Pentagon has the most sides.
