Primary 1 Mathematics Quiz - Shapes - Answer Key

Total Marks: 30

Marking Note: For each question, 1 mark is awarded per correct answer unless stated otherwise. Spelling of shape names must be correct (e.g., "triangle", "rectangle", "circle"). Accept "square" but not "box". Accept "half circle" (two words) or "semicircle". Accept "quarter circle" (two words) or "quarter-circle".

Section A: Identifying Shapes

Concept Recap: A shape is the outline of a 2D (flat) figure. We name shapes by how they look. Recognising shapes is a key skill in P1 Geometry.

1. Triangle

1 mark
Teaching Note: A shape with 3 straight sides and 3 corners is always a triangle. "Tri" means three.

2. Circle

1 mark
Teaching Note: A circle is a round shape. It is special because it has no straight sides and no corners (no pointed parts).

3. Square

1 mark
Teaching Note: A square has 4 sides that are all equal in length and 4 corners. A square is a special type of rectangle, but for P1, treat it as its own shape.

4. Rectangle

1 mark
Teaching Note: A rectangle has 4 sides and 4 corners. The opposite sides are equal in length, but the long sides are longer than the short sides (unless it is a square).

5. Half circle

1 mark
Teaching Note: When you cut a circle into 2 equal parts, each part is called a half circle. It has 1 straight side and 1 curved side.

6. Quarter circle

1 mark
Teaching Note: When you cut a circle into 4 equal parts, each part is called a quarter circle. It has 2 straight sides and 1 curved side.

Section B: Counting Sides and Corners

Concept Recap: Sides are the straight or curved lines that form a shape. Corners (also called vertices) are the points where two sides meet. Circles have no sides and no corners.

7. 3

1 mark
Teaching Note: The triangle in the picture (Q7-fig1) has 3 corners, one at each tip. Each corner is where two straight sides meet.
Common Mistake: Some students count the inside of a triangle as a corner. Only count the pointed parts.

8. 4

1 mark
Teaching Note: A square has 4 equal straight sides. This is a defining property of a square.
Common Mistake: Confusing sides with corners. "Sides" are the lines; "corners" are the points.

9. 4

1 mark
Teaching Note: All rectangles have exactly 4 sides, even though the sides are not all equal in length.

10. 0 (zero)

1 mark
Teaching Note: A circle is perfectly round and has no corners and no straight sides.
Common Mistake: Students may write "1" or "4". Remind them that circles are smooth all the way around with no pointed parts.

Section C: Describing Shapes

Concept Recap: We can describe shapes by counting their straight sides, curved sides, and corners. This helps us tell shapes apart.

11. (a) Half circle — 1 mark (b) 1 — 1 mark

Total: 2 marks
Teaching Note: A half circle has 1 straight side (the cut edge) and 1 curved side (the round part). The two ends of the straight side are the 2 corners.
Expected visual (Q11-fig1): A dome shape with a flat bottom (straight side) and a curved top.

12. (a) Quarter circle — 1 mark (b) 1 — 1 mark

Total: 2 marks
Teaching Note: A quarter circle has 2 straight sides (the two cuts) and 1 curved side (the round edge). The two straight sides meet at 1 corner.
Expected visual (Q12-fig1): A pie-slice or pizza-slice shape.

Section D: Shapes in Real Life

Concept Recap: Many everyday objects look like basic 2D shapes. Recognising shapes in real life helps us connect maths to the world around us.

13. (a) The Clock — 1 mark (b) The Book — 1 mark

Total: 2 marks
Teaching Note: A clock face is round like a circle. A book is shaped like a rectangle (longer than it is wide).
Expected visual (Q13-fig1): Three objects — clock, book, triangular slice.

14. (a) 3 — 1 mark (b) 3 — 1 mark

Total: 2 marks
Teaching Note: A traffic sign (warning sign) shaped like a triangle has 3 straight sides and 3 corners. A triangle always has 3 of each.

Section E: Sorting and Classifying Shapes

Concept Recap: We can sort shapes by their names or by their properties. This is a key skill in geometry.

15. (a) B — 1 mark (b) C — 1 mark (c) D — 1 mark

Total: 3 marks
Teaching Note: Look at the order in the picture: A is a square, B is a triangle, C is a circle, D is a rectangle. Students should match each letter to the correct shape name.
Expected visual (Q15-fig1): 4 shapes labelled A (square), B (triangle), C (circle), D (rectangle), in that order.
Common Mistake: Confusing the square and rectangle. A square has all 4 sides equal; a rectangle has 2 long sides and 2 short sides.

16. (a) 2 — 1 mark (b) 2 — 1 mark (c) 1 — 1 mark

Total: 3 marks
Teaching Note: Count carefully. Each correct count earns 1 mark.
Expected visual (Q16-fig1): 2 squares, 1 triangle, 2 circles, 1 rectangle. Total of 6 shapes.
Common Mistake: Students may miscount circles and squares. Remind them to count each shape type one at a time.

Section F: Combining Shapes

Concept Recap: We can make new shapes by joining two or more basic shapes together. This is called combining or composing shapes.

17. (a) Triangle — 1 mark (b) Square — 1 mark

Total: 2 marks
Teaching Note: A common house shape uses a square for the body and a triangle for the roof. The triangle sits on top of the square, sharing the top side of the square.
Expected visual (Q17-fig1): A house made of 1 square (body) and 1 triangle (roof).

Section G: Properties of Shapes

Concept Recap: Properties are the special features of a shape, like the number of sides or corners. Comparing properties helps us tell shapes apart.

18. (a) Shape 1 (the circle) — 1 mark (b) Shape 2 (the square) — 1 mark

Total: 2 marks
Teaching Note: A circle has 0 corners because it is round. A square has 4 corners, one at each corner where two sides meet at a right angle.
Expected visual (Q18-fig1): A circle labelled "Shape 1" and a square labelled "Shape 2" for clear comparison.

Section H: Word Problems

Concept Recap: When we read a word problem, we look for clues (numbers of sides, corners, equal/unequal) to identify the shape. This connects words to shape properties.

19. (a) Square — 1 mark (b) 4 — 1 mark

Total: 2 marks
Teaching Note: A shape with 4 equal sides and 4 corners is a square. A square always has 4 corners.
Marking: Spelling: accept "square". For (b), accept "4" or "four".

20. (a) Half circle — 1 mark (b) Yes — 1 mark

Total: 2 marks
Teaching Note: When a circle is cut into 2 equal parts, each part is a half circle. Each part has a curved side (the round part of the original circle) and a straight side (the cut).
Marking: For (a), accept "half circle", "semicircle", or "half of a circle". For (b), the answer "Yes" is correct because each half circle still has the curved edge from the original circle.
