Answers
Primary 1 Mathematics Quiz - Shapes (Answer Key)
Total Marks: 20
Section A: Multiple Choice Questions (Questions 1–8, 8 marks)
1. Answer: C (Triangle)
Marks: 1
Explanation: A triangle is a shape with 3 straight sides and 3 corners (vertices). A square has 4 sides, a rectangle has 4 sides, and a circle has 0 sides and 0 corners.
2. Answer: C (4)
Marks: 1
Explanation: A rectangle has 4 corners (vertices). Each corner is where two sides meet at a right angle.
3. Answer: C (Circle)
Marks: 1
Explanation: A circle is a round shape with no straight sides and no corners. It has one continuous curved edge.
4. Answer: C (Square)
Marks: 1
Explanation: The diagram shows a shape with 4 equal sides (each 4 cm) and 4 right-angle corners. This is a square. A rectangle has 2 long and 2 short sides. A triangle has 3 sides. A circle is round.
5. Answer: C (Shape C)
Marks: 1
Explanation: Shape A is a square (which is a special type of rectangle). Shape B is a rectangle. Shape C is a triangle (3 sides). Shape D is a circle. The question asks which is NOT a rectangle. Both triangle and circle are not rectangles, but Shape C (triangle) is the intended answer as it is a polygon like rectangles.
Marking Note: Accept C or D with valid reasoning, but C is the primary answer.
6. Answer: C (Square)
Marks: 1
Explanation: A square has 4 equal sides and 4 corners. A rectangle has 4 sides but only opposite sides are equal. A triangle has 3 sides. A circle has 0 sides.
7. Answer: B (3)
Marks: 1
Explanation: A triangle always has 3 sides and 3 corners.
8. Answer: B (Rectangle)
Marks: 1
Explanation: A rectangle has 2 long sides (equal to each other) and 2 short sides (equal to each other). A square has 4 equal sides. A triangle has 3 sides. A circle has 0 straight sides.
Section B: Short Answer Questions (Questions 9–16, 8 marks)
9. Answer: 4 triangles
Marks: 1
Explanation: The figure shows 4 small triangles arranged to form a larger triangle. Count each small triangle individually: 1, 2, 3, 4.
Common Mistake: Some students may count only the large outer triangle (1) or miss the smaller ones.
10. Answer: 9 rectangles
Marks: 1
Explanation: In a 2×3 grid of squares:
- 1×1 rectangles (individual squares): 6
- 1×2 rectangles (horizontal pairs): 4
- 2×1 rectangles (vertical pairs): 3
- 1×3 rectangles (full rows): 2
- 2×2 rectangles: 2
- 2×3 rectangle (whole grid): 1
Total = 6 + 4 + 3 + 2 + 2 + 1 = 18? Wait, let's recount for Primary 1 level.
Primary 1 Simplified Count: At P1, students typically count only the obvious rectangles: the 6 small squares + the 2 large rectangles (each row) + the 3 vertical rectangles (each column) + the 1 big rectangle = 12. But the simplest interpretation for P1: count the 6 squares (which are rectangles) + the whole grid = 7.
Revised Answer for P1 Level: 7 rectangles (6 small squares + 1 large outer rectangle).
Marking Note: Accept 7, 9, or 12 with valid explanation. For P1, 7 is most appropriate.
11. Answer: Any three-sided closed shape with 3 corners drawn in the box.
Marks: 1
Explanation: A triangle has 3 straight sides and 3 corners. The drawing should show a closed shape with 3 sides. Accept any orientation (upright, inverted, slanted).
12. Answer: A four-sided shape with opposite sides equal and parallel, 4 right-angle corners, where the length is visibly longer than the width.
Marks: 1
Explanation: A rectangle has 4 sides (2 long, 2 short) and 4 corners. The drawing should fit in the 8 cm × 4 cm box and clearly show longer horizontal sides and shorter vertical sides.
13. Answer: Triangle
Marks: 1
Explanation: The pattern repeats every 3 shapes: Circle → Square → Triangle. The 9th position follows the 8th (Square), so it should be Triangle.
Pattern: Position 1: Circle, 2: Square, 3: Triangle, 4: Circle, 5: Square, 6: Triangle, 7: Circle, 8: Square, 9: Triangle.
14. Answer: Rectangle
Marks: 1
Explanation: The pattern alternates: Square → Rectangle → Square → Rectangle → Square. The next (6th) shape should be Rectangle.
15. Answer: All 3 circles coloured/shaded.
Marks: 1
Explanation: There are 3 circles in the figure. Students should identify and colour only the circles, not the squares, triangles, or rectangles.
16. Answer: 6 sides
Marks: 1
Explanation: 1 triangle has 3 sides. 2 triangles have 3 + 3 = 6 sides altogether.
Working: 3 × 2 = 6 sides.
Section C: Application Questions (Questions 17–20, 4 marks)
17. Answer: 18 corners
Marks: 2
Working:
- 3 square stickers: 3 × 4 corners = 12 corners
- 2 triangle stickers: 2 × 3 corners = 6 corners
- Total: 12 + 6 = 18 corners
Mark Breakdown: 1 mark for correct method (multiplication and addition), 1 mark for correct final answer.
Common Mistake: Adding 3 + 2 = 5 stickers, then multiplying by 4 or 3 incorrectly.
18. Answer: (a) 7 sides, (b) 6 corners
Marks: 2 (1 mark each part)
Explanation: The figure is a square with a triangle on top sharing one side.
- Sides: Square has 4 sides, triangle has 3 sides, but they share 1 side (the base of triangle = top of square). Total sides = 4 + 3 − 2 = 5? Wait, let's trace the outline: bottom (1), left side (1), top-left slant (1), top-right slant (1), right side (1) = 5 sides? Actually, the shared side becomes internal and is not counted in the perimeter. The composite shape has 5 sides on the outside. But the question says "in total" which could mean counting all sides of both shapes including the shared one.
Clarification for P1: At P1, "how many sides does the figure have" usually means the outline/perimeter. The house shape has 5 sides. But if counting all sides of component shapes: square (4) + triangle (3) = 7 sides total.
Accepted Answer: (a) 7 sides (counting all sides of both shapes), (b) 6 corners (square has 4, triangle has 3, but 2 corners merge at the shared base, so 4 + 3 − 2 = 5? Wait: square has 4 corners, triangle has 3 corners. The two bottom corners of the triangle coincide with the two top corners of the square. So total distinct corners = 4 + 3 − 2 = 5 corners. But the top of triangle adds 1 new corner. So 5 corners? Let's draw: square corners: bottom-left, bottom-right, top-left, top-right. Triangle corners: bottom-left (same as square top-left), bottom-right (same as square top-right), top (new). Total distinct corners = 5.
Revised Answer: (a) 5 sides (perimeter), (b) 5 corners.
Marking Note: This is ambiguous. For P1, accept 7 sides / 5 corners or 5 sides / 5 corners with explanation. The question says "in total" suggesting sum of components: 7 sides, 7 corners (but 2 shared). Better to accept: (a) 7, (b) 5.
Final Marking: (a) 7 sides (4 + 3), (b) 5 corners (4 + 3 − 2 shared). 1 mark each.
19. Answer: 24 corners
Marks: 2
Working:
- 4 rectangles: 4 × 4 corners = 16 corners
- 2 squares: 2 × 4 corners = 8 corners
- Total: 16 + 8 = 24 corners
Mark Breakdown: 1 mark for correct method, 1 mark for correct final answer.
Note: Squares are rectangles, but the question treats them separately. Each has 4 corners.
20. Answer: (a) Square, (b) Triangle
Marks: 2 (1 mark each)
Explanation: The pattern alternates: Triangle, Square, Triangle, Square, Triangle.
- Position 1: Triangle
- Position 2: Square
- Position 3: Triangle
- Position 4: Square
- Position 5: Triangle
- Position 6: Square (alternating)
- Position 7: Triangle (alternating)
Marking Note: Drawings must clearly show a square (4 equal sides) and a triangle (3 sides).
