Joyful Mathematics 2 — Shapes Around Us. Matching shape properties (sides, corners) in Shapes Around Us supports shape analogies.
What you'll learn
- Shape analogies match properties: sides, corners, roundness.
- Square : 4 sides :: Triangle : 3 sides
- Compare one feature at a time.
Key concepts
Verbal: Shape analogies compare one fact — sides, corners, or round vs straight.
Symbolic: Square : 4 sides :: Triangle : 3 sides. Circle : round :: Square : 4 corners.
Level 1 — Side count
| Shape A | Feature | Shape B | Feature |
|---|---|---|---|
| Square | 4 sides | Rectangle | 4 sides |
| Triangle | 3 sides | Pentagon | 5 sides |
Level 1 — Round vs straight
Circle : no corners :: Square : 4 corners
Level 2 — Same family
Cube : square face :: Box shape with six square faces
Level 2 — Draw it
Sketch shapes to see sides and corners clearly.

Worked example
Circle : Round :: Square : ?
Step 1 — Circle is **round** (no corners)
Step 2 — Square is not round — it has **4 straight sides / corners**
Step 3 — Answer: **4 sides** (or **not round**)
Answer: 4 sides
Common mistakes
| Mistake | Why | Fix |
|---|---|---|
| Colour match | Colour not asked | Match shape facts |
| Size match | Bigger/smaller wrong | Sides/corners |
| 3 sides for square | Count error | Square = 4 |
Quick check
- Triangle : 3 sides :: Pentagon : ?
- Rectangle : 4 sides :: Oval : ?
- Why is 'round' wrong for square?
Stretch: Rectangle : 4 sides :: Oval : ? — is "4 sides" still the best answer? Explain.
Revision tip: Sketch both shapes in an analogy — counting sides beats guessing from memory.
