Play with Patterns

10. Play with Patterns

Patterns Around Us

In everyday life, we see many patterns.
For example, we see:

Barbed wire

Look around you and list three things in which you find some pattern.---------------,------------------,----------------------

Draw some patterns which you have found around yourself.

She makes these designs by using blocks again and again. One day I got hold of the blocks and made a beautiful design

You will see that these designs have been made by using the same block in different ways.
Can you see a pattern in the way each block is repeated?

Pictures in a Pattern

Practice Time
  • Given below are some patterns.
    Figure out the rule for each and continue the pattern.


    • Morning, afternoon, evening, night, morning, ........

Growing Patterns


Can you see the rule and continue the pattern?


Try these also.


My Own Patterns

  • Here is your space to make your own patterns:

    •  
       
       
    •  
       
       
    •  
       
       
    •  
       
       
  • Ask your friends to continue the patterns made by you.

Number Patterns

    We have made some patterns with pictures. We can make patterns with numbers too. Like 21, 41, 61, 81, 101, ...........
    You know the next number, don't you?
    This is a growing pattern. It can go on and on.
    21, 41, 61, 81, 101, 121, 141, 161, ...........

  • Look for the rules and continue these growing patterns:
    • 51, 56, 61, 66, , ,
    • 7, , 21, 28, 35,, ,
    • 2, 4, 8, 16, 32,, ,
    • 12A, 13B, 14C,,
  • Look at these growing patterns. Find out what to add to each number to get the next one:
    • 1, 3, 6, 10,, ,, ,,
    • 0, 2, 6, 12, , ,, ,
    • 1, 3, 7, 13,, ,, ,
    • 2, 3, 6, 11, 18,, ,, ,

This chapter helps children observe and understand patterns around them. They can be given more examples of repeating or growing patterns to recognise the motif or basic unit which generates the patterns. Making secret messages or codes also helps pattern recognition. As their algebraic thinking develops, they will realise that the pattern created by the rule boy boy girl is the same as A A B or ↑↑. Some interesting and important number patterns that relate to mathematical operations are given.

Secret Messages


Amrita and Paritosh are writing secret messages.

Can you tell what they are trying to say?
These are two secret messages. Look for the patterns and find the hidden sentences.

Now you also make your own secret messages.

Even and Odd Number Patterns

91 92 93 94 95 96 97 98 99 100
81 82 83 84 85 86 87 88 89 90
71 72 73 74 75 76 77 78 79 80
61 62 63 64 65 66 67 68 69 70
51 52 53 54 55 56 57 58 59 60
41 42 43 44 45 46 47 48 49 50
31 32 33 34 35 36 37 38 39 40
21 22 23 24 25 26 27 28 29 30
11 12 13 14 15 16 17 18 19 20
1 2 3 4 5 6 7 8 9 10

Half these numbers are in yellow. What patterns do you see in these numbers? Continue the same pattern and fill in the blanks:

96, 98, , 102,,,,.

How far can you continue this pattern?
These numbers have a special name. They are called even numbers.
Do any of these even numbers end with 3 or 5?
What do even numbers end with?
Look at the pattern of numbers in blue. Continue the pattern and fill in the blanks:
99, 101, , 105, 107,, ,


What do the numbers in blue end with?



All numbers that end with 1, 3, 5, 7 or 9 are called odd numbers.
Write all odd numbers between 400 and 410.

___________________________________________________________________________________________________________________________________________________


Write all even numbers between 155 and 165.

___________________________________________________________________________________________________________________________________________________


If we add 1 to any odd number we get an (even/odd) number.



If we add 1 to any even number we get an (even/odd) number


What do you get if you add an even number to an odd number?

Names in an Order


Adil has to arrange this list so that the names starting with A come first and then come those with B, C, D and so on. Number these names in the order in which they will come.

Sharadha        Mahadevan        Tsering        Adil       
Gurinder        Baichung        Harsha        Raja       
Narayan        Kavita        Warsha        Elvis        Jalaj       

Jalaj is proud to have a special name. He says if you read it backwards it is still the same.


Which of the following names have the same pattern? Mark √.
Harsh, Anna, Kanak, Munna, Ongbi
