Understand the idea.
Look at a face or outline
Look for familiar shapes on everyday objects. A book is a solid object, but its flat front face often looks like a rectangle. Say which face or outline you are describing.
The whole object and one face need different descriptions. A box may have a square face, yet the whole box has depth. Calling that face a square does not mean the box itself is a flat square.
Explain what you see
Give a reason for a shape name. A triangular sign has three straight sides around its outline. A rectangular cover has four square corners. Point to the feature that supports your description.
Check sides, corners and curves even when an object is turned. Turning a book does not change the shape of its cover. The direction it points is less useful than the features of its boundary.
See the method in action.
A clock face
A clock has a flat round face with no corners. What shape does the face look like?
Worked solution
- 1
Look only at the clock face.
The question asks about the flat face, rather than the whole clock.
- 2
Check its boundary.
It is round and curved, with no corners.
- 3
Name the familiar shape.
These features match a circle.
A circle.
A book cover
A book cover has four square corners. Two sides are long and two are shorter. What familiar shape fits?
Worked solution
- 1
Check the sides and corners.
The cover has the corners needed for a rectangle.
- 2
Check the side lengths.
There are two long sides and two shorter sides; they are not all equal.
- 3
Name the cover shape.
A rectangle fits because it has four square corners without needing four equal sides.
A rectangle.
Try it yourself.
Check your understanding
A sign's outline has three straight sides and three corners. What shape is the outline?
Show answer & reasoning
A triangle.
The outline is a triangle. It has the defining three straight sides and three corners, even if the sign is turned.

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.
