Answers

Primary 2 Mathematics Quiz - Shapes

Answer Key

Topic: Shapes (2D and 3D Shapes) Total Marks: 30

Section A: Identifying 2D Shapes (Questions 1–5)

1. Answer: Triangle

Marks: 1
Explanation: A triangle is a 2D shape with exactly 3 sides and 3 corners (vertices).
Common mistake: Students may write "rectangle" or "square" — remind them these have 4 sides.

2. Answer: 4

Marks: 1
Explanation: A rectangle has 4 sides and 4 corners. Opposite sides are equal in length.
Common mistake: Some students may confuse sides with corners.

3. Answer: Square

Marks: 1
Explanation: A square has 4 equal sides and 4 corners. All sides are the same length.
Common mistake: Students may write "rectangle" — a square is a special type of rectangle where all 4 sides are equal.

4. Answer: 0

Marks: 1
Explanation: A circle is a round shape with no straight sides and no corners (vertices).
Common mistake: Students may write "1" — remind them a circle has no corners.

5. Answer: Pentagon

Marks: 1
Explanation: A pentagon is a 2D shape with 5 sides and 5 corners.
Note: Students may not yet know "pentagon" by name; accept any reasonable attempt. However, "pentagon" is the expected answer at this level.

Section B: Identifying 3D Shapes (Questions 6–10)

6. Answer: Cube

Marks: 1
Explanation: A cube is a 3D shape with 6 equal square faces. A dice is a common everyday example of a cube.

7. Answer: Cylinder

Marks: 1
Explanation: A cylinder has 2 flat circular faces (top and bottom) and 1 curved face. A can of baked beans is a real-life example.

8. Answer: 3

Marks: 1
Explanation: A cylinder has 3 faces in total: 2 flat circular faces and 1 curved face.
Common mistake: Students may say "1" (counting only the curved face) or "2" (counting only the flat faces). Remind them to count all faces including the curved one.

9. Answer: Sphere

Marks: 1
Explanation: A sphere is a perfectly round 3D shape. A ball (such as a basketball or football) is a common example.

10. Answer: Cylinder

Marks: 1
Explanation: A cylinder has 2 flat circular faces (top and bottom) and 1 curved face wrapping around.
Common mistake: Students may say "cone" — a cone has 1 flat circular face and 1 curved face (not 2 flat faces).

Section C: Properties of Shapes (Questions 11–15)

11. Answer: 12 cm

Marks: 2
Working: 4 + 5 + 3 = 12
Explanation: To find the total length of all three sides, add the lengths together: 4 cm + 5 cm + 3 cm = 12 cm.
Marking note: Award 1 mark for correct working and 1 mark for the correct answer with unit. If the answer is correct but the unit (cm) is missing, deduct ½ mark.

12.

(a) Answer: A square has 4 sides and 4 corners.
(b) Answer: A triangle has 3 sides and 3 corners.
Marks: 2 (1 mark for each part, all blanks correct)
Explanation: A square has 4 equal sides and 4 corners. A triangle has 3 sides and 3 corners.
Common mistake: Students may mix up the number of sides and corners between the two shapes.

13. Answer: Rectangle

Marks: 2
Explanation: A shape with 4 sides where opposite sides are equal (two sides of 6 cm and two sides of 4 cm) is a rectangle. Since not all 4 sides are equal, it is not a square.
Marking note: Award 1 mark for identifying it as a 4-sided shape and 1 mark for naming it correctly as a rectangle. Accept "oblong" as an informal answer but "rectangle" is preferred.

14. Answer: 12 edges

Marks: 2
Working: A cube has 12 edges. Each of the 6 square faces has 4 edges, but each edge is shared by 2 faces. Alternatively, count: 4 edges on the top face + 4 edges on the bottom face + 4 vertical edges connecting them = 12 edges.
Explanation: A cube has 12 edges in total. Students can count them systematically: 4 on top, 4 on the bottom, and 4 connecting the top to the bottom.
Common mistake: Students may say "6" (confusing edges with faces) or "8" (confusing edges with corners/vertices).
Marking note: Award 1 mark for correct working/method and 1 mark for the correct answer.

15. Answer: 6 shapes

Marks: 2
Working: 3 + 2 + 1 = 6
Explanation: Add the number of each type of shape together: 3 triangles + 2 squares + 1 rectangle = 6 shapes in total.
Common mistake: Students may multiply instead of add, or miscount.
Marking note: Award 1 mark for correct working and 1 mark for the correct answer.

Section D: Applying Shape Knowledge (Questions 16–20)

16. Answer: 21 cm

Marks: 2
Working: 7 + 7 + 7 = 21 cm (or 7 × 3 = 21 cm)
Explanation: The perimeter is the total distance around the shape. Since the triangle has 3 equal sides of 7 cm each: 7 + 7 + 7 = 21 cm.
Common mistake: Students may only add two sides, or confuse perimeter with area.
Marking note: Award 1 mark for correct working and 1 mark for the correct answer with unit.

17.

(a) Answer: Triangle
(b) Answer: Rectangle
Marks: 2 (1 mark for each part)
Explanation: In a typical house drawing, the roof is triangular (a triangle shape) and the door is rectangular (a rectangle shape).
Note: This question assumes a standard house drawing with a triangular roof and rectangular door/wall. If students have a different interpretation, use professional judgment.

18. Answer: 6 faces

Marks: 2
Working: A cuboid has 6 faces. It has 8 corners (vertices) and 12 edges. The faces are: top, bottom, front, back, left side, and right side = 6 faces.
Explanation: A cuboid (like a box or brick) has 6 rectangular faces. Even though the question gives the number of corners (8), students need to recall that a cuboid always has 6 faces.
Common mistake: Students may say "8" (confusing faces with corners) or "12" (confusing faces with edges).
Marking note: Award 1 mark for correct working/explanation and 1 mark for the correct answer.

19. Answer: 20 cm

Marks: 2
Working: 5 + 5 + 5 + 5 = 20 cm (or 5 × 4 = 20 cm)
Explanation: A square has 4 equal sides. Each side is 5 cm, so the perimeter is: 5 × 4 = 20 cm.
Common mistake: Students may calculate area (5 × 5 = 25) instead of perimeter. Remind them perimeter is the distance around the outside.
Marking note: Award 1 mark for correct working and 1 mark for the correct answer with unit.

20.

(a) Answer: 12 flat faces
- Working: Each cube has 6 flat square faces. 2 cubes: 6 × 2 = 12 flat faces.
- Explanation: A cube has 6 faces, all of which are flat squares. Two cubes have 6 × 2 = 12 flat faces altogether.
(b) Answer: 1 curved face
- Explanation: A cylinder has 1 curved face (the surface that wraps around the cylinder).
(c) Answer: No, the sphere does not have any flat faces. A sphere has only 1 curved surface all around it.
- Explanation: A sphere (like a ball) is completely round. It has no flat faces at all — only one continuous curved surface.
- Common mistake: Students may think a sphere has 2 flat faces or 1 flat face. Remind them a sphere is perfectly round with no flat parts.
Marks: 3 (1 mark for each part)
Marking note: For part (c), award the mark for a clear explanation that a sphere has no flat faces. Accept answers that demonstrate understanding even if wording differs.
