NCERT Solutions for Class 6 Maths Chapter 3 - Number Play Exercise 3.1

Exercise 3.1

1. What are these numbers telling us? 

Some children in a park are standing in a line. Each one says a number.

2. What do you think these numbers mean?

Ans: The numbers that the children are saying could indicate a pattern or sequence. Based on the image, it looks like there is a repetition of the numbers 0, 1, and 2 in a specific order. These numbers could represent:

• A counting sequence or a cycle: The children may be involved in a game where they are counting in a cyclic manner, repeating the sequence of numbers 0, 1, and 2.

• Positions in line: The numbers could also represent the children's positions or steps in a game or activity, where each child is assigned a number.

• Group identification: The children may be grouped based on these numbers (for example, 0s in one group, 1s in another, and so on).

Try answering the questions below and share your reasoning. 

1. Can the children rearrange themselves so that the children standing at the ends say ‘2’?

Ans: Yes, the children can rearrange themselves so that the children standing at the ends say ‘2’. As long as two children are assigned the number ‘2’, they can be positioned at the ends of the line.

2. Can we arrange the children in a line so that all would say only 0s?

Ans: No, the children cannot all say ‘0s’ unless all of them are assigned the number 0. Based on the image, it appears the numbers are predetermined as 0, 1, and 2, so it is not possible to have all of them saying only 0.

3. Can two children standing next to each other say the same number?

Ans: Yes, two children standing next to each other can say the same number, as long as they are assigned the same number in the sequence. There is no restriction against adjacent children saying the same number.

4. There are 5 children in a group, all of different heights. Can they stand such that four of them say ‘1’ and the last one says ‘0’? Why or why not?

Ans: No, it is not possible for four children to say ‘1’ and the last one to say ‘0’, as the pattern in the image includes more than just 1s and 0s (it includes 2s as well). Based on the existing set of numbers (0, 1, 2), you cannot assign ‘1’ to four children while leaving one child with ‘0’.

5. For this group of 5 children, is the sequence 1, 1, 1, 1, 1 possible?

Ans: No, the sequence 1, 1, 1, 1, 1 is not possible, as the pattern involves a variety of numbers (0, 1, and 2), and all the children cannot be assigned the same number, in this case, all 1s.

6. Is the sequence 0, 1, 2, 1, 0 possible? Why or why not?

Ans: Yes, the sequence 0, 1, 2, 1, 0 is possible. This sequence follows a valid pattern where each child can be assigned one of the numbers 0, 1, or 2. The pattern repeats but still includes the available numbers.

7. How would you rearrange the five children so that the maximum number of children says ‘2’?

Ans: To maximise the number of children saying ‘2’, you would arrange the children so that as many as possible are assigned the number ‘2’. If there are no restrictions, and based on how the numbers are assigned, you could potentially arrange the children so that 3 out of 5 say ‘2’, while the remaining two children could be assigned 0 or 1.
