Pattern 1:

Pattern 2.

Pattern 3.

The answer may vary from student to student.  The answer provided here is only for reference.

2. Yamini has used her blocks to make a few patterns. Help her to take these patterns forward.

Ans:

Pattern 1:

In this pattern the leaf is rotated by 90 degrees each time as we move forward and attached to the previous one until we get the same pattern as 1st. so this pattern continues as follows.

Pattern 2:

In this pattern in the 1st row 1 column there are 2 sticks having an upward arrow and in the 1st row 2 column there are 2 sticks having a downward arrow and the pattern continues with an increase of 1 stick having one upward and 1 downward pattern respectively. So this pattern continues as follows.

Pattern 3:

As we move forward in this pattern we see that the circle is rotated by 90 degrees each time. So this pattern continues as follows.

3. We can also make patterns with numbers and letters. Below are a few examples. Can you take them forward?

Ans: Pattern 1: In this pattern the alphabets of the English language are written in the pair of 3 alphabets in one. So this pattern continues as follows.

Pattern 2: In this pattern the counting and the alphabet’s both are in reverse order as we move forward. So this pattern continues as follows.

Pattern 3: In this pattern the upcoming triangle is filled by a number which is obtained by subtracting 100 from the previous one. So this pattern continues as follows.

Pattern 4: In this pattern the upcoming triangle is filled by a number which is obtained by adding 100 in the previous one. So this pattern continues as follows.

4. Now write your own number patterns.

13. Teenu wants to write to his friend ‘Good Morning’. What will he write by using the same rule?

Ans: In this question, we have to follow the rule of the previous question.

As,

G=7; O=15; O=15; D=4

And M=13; O15; R=18; N=14; I=9; N=14; G=7;

So, by using the same rule ‘Good Morning’ is written as.

14. If we change the rule and write 1 in place of ’B’, 3 in place of ‘D’ and so on, then how will we write ‘Let Us Dance’?

Ans: In this question, it is mentioned that ‘B’ is coded as ‘1’ and ‘D’ is coded as ‘3’

That means the counting of letters starts from ‘0’ for this question.

So, L=11; E=4; T=19

U=20; S=18

D=3; A=26; N=13; C=2; E=4

Glimpses of Class 4 Maths Chapter 10 – Play with Patterns

Class 4 Maths Chapter 10 – Play with Patterns, teaches us how to recognize growing and reducing patterns in pictures and numbers. You will also be able to identify the rule for growing and reducing patterns and extend the patterns using rules. 

We see patterns everywhere around us. They could be in our clothes that we wear or bed sheets or curtains in our homes or in the toys that we play, etc. So what is a pattern? Patterns are created when figures, shapes, objects, etc. are arranged in a particular order and repeated over and over again. We must have seen different kinds of patterns in our daily life. 

Let us look at the pattern below.

ΟΔ• ------ ΟΔ• ----- ΟΔ•

↑          ⎯⎯⎯⎯⎯⎯

This is a Pattern      this is repeated.

Maths is full of patterns. We find patterns in alphabets, numbers, shapes, etc. 

For example: Let us see the Table of 2.

2, 4, 6, 8, 10, 12, 14, 16, 18, 20,……. We are skipping each number by 2. 

Once you know the rule for a pattern you can continue the pattern. 

Growing and Reducing patterns

Picture Patterns: A picture can be made by increasing or decreasing the number of objects.

This is a growing pattern. The rule followed in the pattern is that the number of squares increases by 1 each time. 

In the next picture

(image will be uploaded soon)

This is a reducing pattern. The rule followed is that the number of circles decreases by 1 each time. 

Number Patterns: Increasing and decreasing patterns can be formed with numbers also.

Example: 1, 3, 5, 7, 9, ….. ? What will be the next number ?

This is a growing pattern. The rule followed is that the next number is obtained by adding 2 to the previous number. 

So, the next number is: 9 + 2 = 11.

Let us see the reducing pattern. 

Example: What is the next number in the pattern: 20, 18, 16, 14, …..?

This is a reducing pattern. The rule followed is that the next number is obtained by subtracting 2 from the previous number. 

So, the next number is: 14 – 2 = 12.

What is a Number Tower?

Number Tower is a fun puzzle for children where numbers are arranged in a tower. We start calculating from the below of the tower and get to the number at the top of the tower following the rule of pattern. 

48

20      28

8       12         16

Let us check how we arranged the numbers in the above tower. We start from the below and get this number pattern. Can you follow the rule of this pattern?

We added 2 numbers in the below boxes to get the number in the box above them.

We add 8 + 12 = 20; 12 + 16 = 28; 20 + 28 = 48

Same Sum Rule

In this rule, we get the same result each time when we add two numbers.

Example:  10 + 5 = 15

        11 + 4 = 15

        12 + 3 = 15

We can use the pattern in creating secret messages like coding and decoding. 

Say, we code a particular word with a pattern of numbers and then the word is decoded. This can be used when we have to send some secret message to someone.
