Learning Outcomes

Students will be able to learn:
 patterns with a unit of repeat and their extension.
 progressive patterns and their extension.
 patterns with more than one characteristic.
 triangular and square numbers.

Patterns are a group of shapes, numbers, designs or letters that are arranged in a particular
sequence according to a rule. They usually repeat themselves or grow or reduce in a predictable
manner.
An element is any single item or step of the pattern. We can arrange numbers, shapes and figures
together to make patterns. Let’s revise the concepts related to patterns that we have studied
earlier and learn more about patterns in this class.
Patterns with a Unit of Repeat Remember

A pattern with an identifiable unit of repeat is called a repeating A unit of repeat or core
pattern. It can be made using different shapes, sizes, colours, is the smallest unit that
letters and numbers. repeats again and again
in a pattern.
Observe the patterns shown below and their unit of repeat.
