Pattern 

• A pattern is a recurring arrangement of numbers, forms, colours, and so on. The Pattern can be associated with any kind of event or object. 

• If a group of numbers is connected to one another in a certain way, such a rule or manner is referred to as a pattern. Patterns are also referred to as sequences. 

• For example, 2,4,8,16,32,... these are related to each other in the sense that the next number is the previous number multiplied by 2.

Number Pattern 

• Patterns or number patterns in maths are a set of numbers that follow a specific order. Number pattern for class 3 is classified as algebraic or mathematical patterns. 

• For example: 1,3,5,7,9,....

Shape Pattern 

• Shape patterns form when a set of shapes is repeated repeatedly. 

• These patterns adhere to a specific sequence, or order, of forms, which is then repeated at least twice. For example, 

Shape Patterns

Solved Example for Shape Pattern

a.   

Shape pattern of flowers

Answer:

Shape pattern of flower

In the above figure, if we observe, it is a repeating pattern, therefore after the 4 petals diagram, the full-grown flower is the successive pattern.

b.

Shape pattern of Ice cream

Answer:

 

Ice cream

In the above figure, if we observe, it is a repeating pattern, therefore after the half-drawn ice cream, full ice cream with the eye is the successive pattern.

c. 

Shape pattern of Cartoons

Answer:

 

Shape pattern of Cartoon

d.

Shape pattern of Semicircles

Answer: If we look at the last semicircle given, it is the same as the first one. Therefore, the pattern is repeated.

 

Shape pattern of Semicircles

e. 

Shape pattern of planets

Answer:

 

Shape pattern of planets

If we look at the given pattern, it is a repeating pattern, therefore after the purple planet, the yellow moon will come.

f. 

Shape pattern of rotating semicircle

Answer:

 

Shape pattern of rotating semicircle 

In this pattern, the hollow semi-circle is rotating clockwise, therefore the next hollow semi-circle facing upwards.

Pattern Varieties: In Discrete Mathematics, there are three types of patterns:

Repeating pattern: 

• It is a form of pattern in which the rule is repeated again and over again.

Repeating pattern

• In the above image, we can see that after each blue triangle we have two reverse yellow triangles, hence it has a repeating pattern.

Growing: 

• If the numbers are in increasing order, the pattern is said to be a growing pattern. 

Growing pattern

• In the above image, the dots are increasing from 1 dot to 4 dots then to 9 dots, these numbers are squares of 1, 2,3 and so on, therefore these patterns are growing.

Shrinking: 

• The numbers in the shrinking pattern are in decreasing order. 

Shrinking pattern

• In the above image, the blocks are decreasing from 10 to 8 to 6, since the numbers are reducing therefore we can say that the pattern is shrinking.

Even Number 

• Even numbers may be split into two equal groups or pairs and are completely divisible by 2. 

• For instance, 2, 4, 6, 8, 10, and so forth.

Odd Number 

• Odd numbers are those that cannot be divided evenly by two. It cannot be equally split into two independent integers. 

• For example, 1,3,5,7,...

Ascending Order

• When numbers are sorted from smallest to greatest, they are said to be in ascending order. 

• For example, 91,92,93,94,.... 

Solved Example for Ascending Order

Ascending Order of certain alphabets

Answer:

 

Ascending Order of certain alphabets

In this ascending pattern, the vowels are listed therefore, after A, E, I, O, U will come.

Descending Order

• When numbers are organised from largest to smallest, they are said to be in descending order. 

• For example, 99,98,97,96,95,....

Solved Example 1. 90,85,80,75,70,___,____,_____. Fill in the blanks.

Ans: If we look at the numbers, they are reduced by five. Therefore, the next three numbers should be 65,60,55.

Practice Problems

1. Observe the growing pattern and fill in the blanks: 

1. 1,3,5,7,9,___,___,___.

Ans: If we observe the numbers here they are increasing by 2 therefore, the next 3 numbers are 11,13,15.

b. 2,4,6,8,___,___,____

Ans: If we look at the pattern here it is increasing by 2 therefore, the next 3 numbers are 10,12,14.

c. 10A, 11B,12C,____,____,____

Ans: In this pattern, there are two things to keep in mind. First, the numbers are increasing by one and the second are the letters are also increasing by one therefore, the next three numbers will be 13D,14E, and 15F.

d. 3,6,12,24,___,___,___

Ans: In this case, it is a growing pattern where 3 is added by 3 to give 6, then 6 is added by 6 to give 12, similarly 12 is added by 12 to give 24, therefore the next three numbers are 48,96,192.

e. 0,5,15,30,___,___,___

Ans: Here the difference between the first and the second number is 5, the second and third number is 10, third and fourth is 15 therefore, the next number should be 30+20, 50+25 and 75+30, therefore the answer is 50,75,105.

 2. Let’s have fun with patterns, mark the correct answer from the following.

Shape Pattern Question

Ans:

 

Shape Pattern

Importance of CBSE Class 3 Maths Chapter 10 Play with Patterns

As mentioned earlier, this chapter explains the different types of patterns for the Class 3 standard. Arithmetic questions involving pictures related to patterns will benefit the students in the following ways.

• Recognition of different patterns

Class 3 students will be able to understand the different types of patterns. Eventually, they will learn how to determine a pattern and understand the meaning of a question.

• Developing logical reasoning skills

Students will develop logical reasoning skills by solving questions related to patterns in maths for Class 3. The questions will require comprehension of different patterns in pictures. They will learn how to concentrate and explain the existence of a pattern in every question with their logic.

• Using geometrical skills

As we proceed deeper into the concepts related to object and number pattern for Class 3, we will observe that the problems contain geometrical shapes too. It helps the students to become better at recognising geometric figures along with other intricate patterns.
