#### Question 1:

Growing Patterns

Can you see the rule and continue the pattern?

In 1st image, there is only 1 arrow head pointing in the upward direction. In 2nd image, there is only 1 arrow head and is pointing in the downward direction. In 3rd image, there are only 2 arrow heads pointing in the upward direction. In 4th image, there are only 2 arrow heads pointing in the downward direction.

Similarly, the arrowheads become 3 in 5th and 6th image, pointing upward and downward alternately. So, in 7th and 8th image of the pattern, there will be 4 arrowheads, pointing upward and downward alternately.

Try these also.

Disclaimer: The patterns may vary from student to student. It is highly recommended that the student prepares the answer on their own.

#### Question 3:

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, ………

21, 41, 61, 81, 101, 121, 141, 161, 181201221241261281301………….

#### Question 1:

A Look for the rules and continue these growing patterns: (a) 51, 56, 61, 66, _____, _____ ……. (b) 7, _____, 21, 28, 35, _____, _____ …… (c) 2, 4, 8, 16, 32, _____, _____, _____ (d) 12A, 13B, 14C, _____, _____.

(a) 51 + 5 = 56 56 + 5 = 61 So, we keep adding 5 in the next number to complete the pattern further. 51, 56, 61, 66, 717677 …….

(b) 7

×1 = 7 7

×2 = 14 7

×3 = 21 So, we keep writing table of 7 to complete the pattern further. 7, 14, 21, 28, 35,4249, ……

(c) 2

×1 = 2 2

×2 = 4 2

×4 = 8 2

×8 = 16 So, we keep multiplying 2 with the previous answer received to complete the pattern further. 2, 4, 8, 16, 32, 64128256

(d) Here each number increases by 1 and alphabets are written in their order along with the increasing numbers. 12A, 13B, 14C, 15D16E.

#### Question 2:

Look at these growing patterns. Find out what to add to each number to get the next one: (a) 1, 3, 6, 10, _____, _____, _____, _____, _____ (b) 0, 2, 6, 12, _____, _____, _____, _____, _____ (c) 1, 3, 7, 13, _____, _____, _____, _____, _____ (d) 2, 3, 6, 11, 18, _____, _____, _____, _____, _____

(a) 1 + 2 = 3 3 + 3 = 6 6 + 4 = 10 10 + 5 = 15 1, 3, 6, 10, 1521283645.

(b) 0 + 2 = 2 2 + 4 = 6 6 + 6 = 12 12 + 8 = 20 0, 2, 6, 12, 2030425672.

(c) 1 + 2 = 3 3 + 4 = 7 7 + 6 = 13 13 + 8 = 21 1, 3, 7, 13, 2131435773

(d) 2 + 1 = 3 3 + 3 = 6 6 + 5 = 11 11 + 7 = 18 2, 3, 6, 11, 18, 2738516683.

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.

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?

All these numbers have either 0, 2, 4, 6 or 8 at their units place. 96, 98, 100, 102, 104106108110112……

This can be continued without any end.

No, none of these even numbers end with 3 or 5.

Even numbers end with 2, 4, 6, 8 or 0. 99, 101, 103, 105, 107, 109111113…….

Numbers in blue end with 1, 3, 5, 7 or 9.
