Real world shapes
Let’s match the shape to the following real-world object.
Select the correct answer, then press ‘Check Answer’ to reveal how you did.
Brainstorm
What do you notice?
While exploring the shapes, reflect on the following questions:
- What do you notice about each shape?
- How are the shapes similar?
- How are the shapes different?
Record your ideas in a notebook or a method of your choice.
Action
Shapes attributes
What makes each two-dimensional shape special?
Each shape has something called attributes.
An attribute is a characteristic that can be used to describe and compare things.
Some attributes of shapes include:
- number of sides
- number of equal side lengths
- number of corners, and if they are square
- types of sides (straight or curved)
Here are some attributes found in a circle and a hexagon.
Circle
A circle is a two-dimensional shape with a curved side.
A real-world example of a circle is a hula hoop.
Hexagon
A hexagon is a two-dimensional shape with six sides and six corners.
A real-world example of a hexagon is beehive cell. The six sides of a beehive cell form a hexagon.
Student Tips
Did you know?
A polygon is a closed shaped with at least three sides and corners.
For example, a triangle, pentagon, hexagon, and octagon are all polygons.
A polygon cannot have curved sides.
Now, let’s explore how shapes are similar and different.
Comparing two-dimensional shapes
How are shapes similar? How are they different?
Let’s examine a square and a rectangle.
Both a square and a rectangle have four sides and four square corners.
A square has four equal side lengths.
A rectangle has two short sides, and two long sides.
Compare: Triangle and pentagon
Now, let’s examine and compare a triangle and a pentagon.
Consider the following:
- How many sides does each shape have?
- How many equal side lengths does each shape have?
- How many corners does each shape have?
- Are the sides straight or curved?

Sorting rule
Let's examine the following groups of shapes.
Determine the sorting rule and explain your thinking. Record your ideas in a notebook or a method of your choice.
Press ‘Sorting Rule’ to reveal the sorting rule for Group 1 Shapes.
Sorting RuleThe sorting rule is to group shapes with more than 3 sides.
Hence, the group has shapes with more than 3 sides.
The triangle is outside of the group because it has 3 sides.
Press ‘Sorting Rule’ to reveal the sorting rule for Group 2 Shapes.
The sorting rule is to group shapes with 4 equal sides.
Hence, the group has shapes with 4 equal sides.
The rectangle is outside of the group because it has 2 sides that are long, and 2 sides that are short.

Shape riddle
Let’s create a shape riddle!
Your riddle should include three different shape attributes:
- the number of sides
- the number of corners
- the real-world object your shape resembles
Riddle example:
