The idea, step by step
Look at a face or outline
Everyday objects can show familiar shapes. A book's front face often looks like a rectangle.
The whole book is a solid object. Its flat front face can be described using a flat shape.
Explain what you see
A shape name needs a reason. Say that a sign looks triangular because its outline has three straight sides.
Objects and pictures may be turned. Look at the sides, corners and curves instead of which way they point.
A common trap
A box is a square because one face looks square.
Instead: A box is a solid object. One of its flat faces may be a square.
See the thinking
A clock face
A clock has a flat round face with no corners. What shape does the face look like?
- Look only at the face.
- It has a curved boundary and no corners.
A book cover
A book cover has four square corners. Two sides are long and two are shorter. What familiar shape fits?
- There are four straight sides and four square corners.
- A rectangle does not need all four sides equal.
Check your understanding
A sign's outline has three straight sides and three corners. What shape is the outline?
Show answer
A triangle.
The side and corner counts identify it.

Read the worked solutions
- A plate's top outline is round with no corners. Which flat shape does it look like?
The outline is curved all around.
A circle. - A tiled floor uses four-equal-sided tiles with square corners. Name their shape.
Each tile has four equal sides and four square corners.
Squares. - A book cover is shaped like pictured C. Name the shape.
C has four square corners with two longer sides.
A rectangle. - Is a real ball a circle or a solid object?
It takes up space, although a flat drawing can look circular.
A solid object. - A triangular sign is turned sideways. Does its outline stop being a triangle?
Turning does not change the three sides and corners.
No. - Find a safe everyday object. Draw one face or its outline and name a matching flat shape.
Name the face or outline and explain using sides, corners or curves.
Answers vary: for example, draw a rectangular book cover or circular lid.
