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
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.
Conclusion
Recognizing patterns for coding and decoding is important for the development of Mathematical skills. With these basic rules and concepts of patterns now you can solve any kind of reasoning questions. You just need to observe the pattern very carefully and then decode it.
