Primary 1 Mathematics Quiz – Shapes: Answer Key
Topic: Shapes (2D Shapes – Triangle, Square, Rectangle, Circle) Total Marks: 30
Section A: Identifying Shapes (Questions 1–5)
Each question carries 1 mark.
1. Which shape has 3 sides?
Answer: B. Triangle
Explanation: A triangle is a shape with exactly 3 straight sides and 3 corners. Students should recall that "tri-" means three.
Marking Notes: Award 1 mark for selecting B. No mark for any other option.
2. Which shape has 4 equal sides?
Answer: C. Square
Explanation: A square has 4 sides that are all the same length. A rectangle has 4 sides but only opposite sides are equal.
Marking Notes: Award 1 mark for selecting C. Common mistake: students may select B (rectangle) because it also has 4 sides, but the key phrase is "4 equal sides."
3. Which shape is round and has no corners?
Answer: B. Circle
Explanation: A circle is a round shape with no straight sides and no corners (vertices).
Marking Notes: Award 1 mark for selecting B.
4. Look at the shape. What is it?
Answer: C. Rectangle
Explanation: A rectangle has 4 sides and 4 corners. Opposite sides are equal. It looks like a stretched square. Students should identify it by counting sides and noting that adjacent sides are not all the same length.
Marking Notes: Award 1 mark for selecting C.
5. Which of these shapes has exactly 4 sides but NOT all sides equal?
Answer: D. Rectangle
Explanation: A rectangle has 4 sides, but only the opposite sides are equal. The top and bottom are the same length, and the left and right are the same length, but they are different from each other. A square has all 4 sides equal.
Marking Notes: Award 1 mark for selecting D. This question tests the distinction between a square and a rectangle.
Section B: Properties of Shapes (Questions 6–10)
Each question carries 2 marks.
6. A triangle has ______ sides and ______ corners.
Answer: 3 sides and 3 corners
Explanation: By definition, a triangle has 3 straight sides and 3 corners (vertices). Students can count the sides and corners of any triangle drawing to verify.
Marking Notes: Award 2 marks for both correct answers (3 sides, 3 corners). Award 1 mark if only one part is correct.
7. A square has ______ sides. All its sides are ______ (equal / not equal).
Answer: 4 sides. All its sides are equal.
Explanation: A square is a special 4-sided shape where every side is the same length. This distinguishes it from a rectangle.
Marking Notes: Award 1 mark for "4 sides" and 1 mark for "equal." Award 1 mark if only one part is correct.
8. A circle has ______ corners.
Answer: 0 corners
Explanation: A circle is a curved shape with no straight sides and therefore no corners (vertices).
Marking Notes: Award 2 marks for "0" or "zero." Accept "no corners" as a written response.
9. A rectangle has ______ sides. Its opposite sides are ______ (equal / not equal).
Answer: 4 sides. Its opposite sides are equal.
Explanation: A rectangle has 4 sides and 4 corners. The top and bottom sides are equal in length, and the left and right sides are equal in length. However, the top and left sides may be different lengths.
Marking Notes: Award 1 mark for "4 sides" and 1 mark for "equal."
10. Fill in the table.
| Shape | Number of Sides | Number of Corners |
|---|---|---|
| Triangle | 3 | 3 |
| Square | 4 | 4 |
| Rectangle | 4 | 4 |
| Circle | 0 | 0 |
Explanation: Students should recall the defining properties of each basic 2D shape. A circle has 0 straight sides and 0 corners because it is entirely curved.
Marking Notes: Award ½ mark for each correct cell. Total: 8 cells × ½ mark = 4 marks, scaled to 2 marks (award 2 marks for all correct, 1 mark for 4–6 cells correct, 0 marks for fewer than 4).
Section C: Shapes Around Us (Questions 11–15)
Each question carries 2 marks.
11. Name a shape that looks like a door.
Answer: Rectangle
Explanation: A typical door is taller than it is wide, with 4 sides and 4 corners. Opposite sides are equal. This matches the properties of a rectangle.
Marking Notes: Award 2 marks for "rectangle." Accept reasonable alternatives with explanation (e.g., "a rectangle because it has 4 sides and is tall"). Award 1 mark if the student draws a rectangle without naming it.
12. A slice of pizza looks like which shape?
Answer: Triangle
Explanation: A typical pizza slice has two straight edges and a curved crust edge, but in simplified Primary 1 context, it is treated as a triangle (3-sided shape).
Marking Notes: Award 2 marks for "triangle." This connects real-world objects to mathematical shapes.
13. A wheel looks like which shape?
Answer: Circle
Explanation: A wheel is round with no corners, matching the properties of a circle.
Marking Notes: Award 2 marks for "circle."
14. A chessboard is made up of small ______ (squares / circles / triangles).
Answer: squares
Explanation: A chessboard is a grid of 64 small equal-sized squares (8 rows × 8 columns). Each small section has 4 equal sides and 4 corners.
Marking Notes: Award 2 marks for "squares."
15. The face of a clock looks like which shape?
Answer: Circle
Explanation: Most traditional clock faces are round, which is the shape of a circle. Some clocks may be square or rectangular, but the standard reference for Primary 1 is a circle.
Marking Notes: Award 2 marks for "circle." Accept "rectangle" or "square" if the student explains they are thinking of a digital clock or a specific clock they have seen, but the expected answer is "circle."
Section D: Drawing and Combining Shapes (Questions 16–20)
Each question carries 3 marks.
16. Draw a triangle. Label the number of sides and corners.
Answer: (Student should draw a shape with 3 straight sides and 3 corners.)
Explanation: The drawing must show a closed shape with exactly 3 straight sides and 3 corners. It does not need to be a perfect equilateral triangle — any triangle (scalene, isosceles, or equilateral) is acceptable.
Marking Notes:
- Award 1 mark for drawing a closed 3-sided shape.
- Award 1 mark for correctly identifying/labeling 3 sides.
- Award 1 mark for correctly identifying/labeling 3 corners.
- If the shape is not closed or has the wrong number of sides, award 0 marks for the drawing component.
17. Draw a square and a rectangle. Write one way they are the same and one way they are different.
Answer:
- (Student should draw a square and a rectangle.)
- Same: Both have 4 sides and 4 corners. (Also accept: both are 4-sided shapes / both have 4 corners.)
- Different: A square has all 4 sides equal; a rectangle has only opposite sides equal. (Also accept: a square's sides are all the same length but a rectangle's sides are not all the same length.)
Explanation: This question assesses whether students understand the relationship between squares and rectangles. A square is a special type of rectangle where all sides happen to be equal.
Marking Notes:
- Award 1 mark for correct drawings of both shapes.
- Award 1 mark for a valid similarity (e.g., both have 4 sides, both have 4 corners).
- Award 1 mark for a valid difference (e.g., side lengths differ).
18. How many triangles can you see in this figure?
(A large triangle divided into 4 smaller triangles by connecting the midpoints of each side.)
Answer: 5 triangles
Explanation: There are 4 small triangles inside the large triangle, plus the large triangle itself. Total = 4 + 1 = 5 triangles.
Marking Notes:
- Award 3 marks for the correct answer: 5.
- Award 2 marks if the student counts only the 4 small triangles (missing the large outer triangle).
- Award 1 mark if the student counts some but not all triangles.
- Common mistake: Students often forget to count the large outer triangle.
19. Use two squares to make a new shape. Draw the new shape and name it.
Answer:
- (Student should draw two squares placed side by side or one on top of the other, forming a rectangle.)
- Name of new shape: Rectangle
Explanation: When two identical squares are joined along one complete side, the resulting shape is a rectangle. The new shape has 4 sides, with the two longer sides equal to twice the side of one square, and the shorter sides equal to the side of one square.
Marking Notes:
- Award 1 mark for a drawing showing two squares joined together.
- Award 1 mark for the resulting shape being a rectangle (or a valid composite shape).
- Award 1 mark for naming the new shape correctly as a rectangle.
- Accept creative arrangements (e.g., L-shape) with appropriate naming, but the most straightforward answer is a rectangle.
20. Look at the pattern. What shape comes next? Draw it.
(Pattern: circle, square, triangle, circle, square, triangle, circle, square, ____)
Answer: Triangle
Explanation: The pattern repeats every 3 shapes: circle → square → triangle. The sequence is:
- Position 1: circle
- Position 2: square
- Position 3: triangle
- Position 4: circle
- Position 5: square
- Position 6: triangle
- Position 7: circle
- Position 8: square
- Position 9: triangle
Since 9 is a multiple of 3, the 9th shape is a triangle.
Marking Notes:
- Award 2 marks for the correct answer: triangle.
- Award 1 mark for a correct drawing of a triangle.
- Total: 3 marks (2 for identifying, 1 for drawing).
- Common mistake: Students may not recognise the repeating pattern and guess randomly.
