1. Can you see how Tinu has made different patterns using the same block? Now you too make 3 different patterns using

.

Pattern 1.

Pattern 2.

Pattern 3.

Ans: In this question we have to make 3 patterns such that they repeat after some blocks. So, the reference patterns are as follows.

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 1^st. 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.

Ans: In this question, we have to make our own number patterns. This pattern are for reference only.

Pattern 1:

In this pattern, we start with 100 and add 100 as we move forward.

Pattern 2:

In this pattern, we start with 850 and subtract 100 as we move forward.

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

5.Make a pattern without numbers.

Ans: In this question, we have to make a pattern which does not contain the numbers.

So, In this pattern we write English alphabets in pairs of 2.

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

6.Now you try writing the letters – A, B, C in the box so that no letter comes twice in any line.

Ans: In this question, we have to fill the above squares with the letter’s A, B, and C. Such that no letter comes twice in any line. So, the pattern is as follows.

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

7.Now you fill these stars. Use numbers 1-9 and the rule that the number on each line adds up to 15.

Ans: In this question, we have to fill the above stars with the numbers 1 to 10. Such that the number on each line adds up to 15. So, the pattern is as follows.

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

8.Now use numbers 1-6 to make your own magic triangle. Rule: numbers on each side must add up to 10.

Ans: In this question, we have to fill the above stars with the numbers 1 to 6. Such that the number on each side adds up to 10. So, the pattern is as follows.

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

9.Now you write any number and the three numbers after that. Make a pattern using the rule.

Ans: In this question, it is given that we have to write the numbers in series and we can start that series with any number. Such that the additional table given makes a rule for this particular question. So the pattern is as follows. And the rule is that the sum of the first and last number and the sum of 2^nd and 2^nd last number is equal in this case the sum in 15.

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

10. Using the same rule. Complete these number towers.

Ans: Pattern 1:

In this pattern, the rule is that the sum of numbers in the lower 2 circles is the number in the upper circle. So the pattern continues as follows.

Pattern 2:

In this pattern, the rule is that the sum of numbers in the lower 2 squares is the number in the squares. So the pattern continues as follows.

11.Now, you try to make such a pattern with 5 numbers in order.

Ans: In this question, we have to make a pattern such that the sum of the first 5 numbers of a row is equal to the 6th number. And that 5 numbers and the respective sum also makes a pattern itself. So, the pattern is as follows.

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

12.Complete this list of letters and numbers to help you.

Ans: In this question, it is clearly seen that the 1^st row continues with English alphabets and the 2^nd row continues with the numbers of that alphabet according to the English language. So the pattern is as follows.

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

15.What was Kahuli's secret message?__________

What did shablu and jaggu write?_________________________. Use the same rule to write- ‘Meet me on the moon’.__________________________Make different rules and ask your friends to crack the secret message.
