QUICK CONCEPT REVIEW
Have you seen a rangoli? Rangoli is made by following a particular pattern
A pattern is a repetitive design and can be seen around us.
How pattern is formed?
A pattern can be formed by using numbers, alphabets shapes or colours.
When objects or shapes are placed in an order, they form a pattern. A pattern follows a rule that allows us determine to what comes next in the sequence.
The migratory birds fly in V-Shape pattern so that they can reach the destination.
Real Life Examples:
The traffic light follows a pattern of 3 colours which repeats after few seconds to avoid traffic jam.
The pattern of white and black strip is present on the bod of zebra.
Where do we see Patterns in our everyday life?
We see patterns everywhere around us. For example: in the designs of a dress, in the design of an umbrella (on the basis of colours) and in the design of mehendi.
A repeating pattern is a cyclic repetition of a particular element.
TYPES OF PATTERN
There are different types of patterns. Let us discuss them in detail.
1. NUMBER PATTERN
A list of numbers that follow certain sequence of pattern is known as number pattern
Hence, number of pencils is increasing by the difference of 2 in each step.
Same is happening in the case of example of pattern of number of butterflies shown below.
2. LETTER PATTERN
Patterns can also be made with either same or different letters.
AA BB CC DO EE
A AB ASC ABCD ABCDE
A B A B A
A 5 A S A
3. COLOUR PATTERN
An arrangement of different colours to form a pattern is called a colour pattern.
In Rangoli we use different colours to make different designs.
Pattern is a particular arrangement made in different styles of numbers and various shapes and sizes.
Pattern of various designs are made on various monuments and temples in ancient time.
4. INCREASING AND DECREASING PATTERNS
Increasing Number Pattern: A growing pattern in which number keeps on increasing is called increasing number pattern.
In this pattern, the numbers are increasing by adding number '2' to each previous number.
Decreasing Number Pattern: A degrowing pattern in which number decreases is called decreasing number pattern.
In this pattern, the numbers are decreasing by subtracting number '1' from each previous number.
