# 6. Fun with Give and Take

## Cricket Match

In a cricket match, Sri Lanka made 235 runs.

India has made 123 runs. How many more runs does India need to win?

To win India must make 236 runs. Runs India needs to win:

236 - 123 = ?

## Try it Yourself

Geeta had Rs 368 in her purse.

She bought a book for Rs 123.

How much money is left in her purse?

Money left in her purse is Rs 368 - Rs 123 = ?

## Can You Help Nabeela?

Nabeela's mother sent her to the market to buy some things.

She gave her Rs 245. Nabeela bought 1 kg ghee for Rs 127. The shopkeeper gave her back Rs 98.(Kilogram is written as kg.)

Did the shopkeeper give her the right amount?

Let's find out.

The shopkeeper had to give Nabeela Rs 118.

How much more money should the shopkeeper give Nabeela? |

The teacher should encourage students to discuss and correct the wrong answers. Children love to correct others' mistakes (for a change!) and also learn from this process. |

## Let's Deliver Letters

Postman Uncle is ill today. Let's deliver the letters for him.

Write the correct room numbers on the letters. Then find the rooms in the above building and circle them.

The teacher should encourage students to solve the problems mentally using the above chart. |

## Find the Missing numbers

Look at the number patterns. Write the missing numbers.

100, 200, 300, ,, 600,.

50, 100, 150, 200,, ,,.

280, 260, 240,, ,,.

## Mental Maths

## Story Problems

Nisha and Sonu were making story problems. Nisha said - 13 boys and 14 girls in a class. Sonu, can you make a problem on it?

There are 13 boys and 14 girls in a class. |

How many students are there altogether? |

You can also make story problems with your friends. Look at each picture and the words next to it. Write your problem below it.

36 men and 52 women waiting for their turn

We have our mid-day meal in 20 minutes and play for 15 minutes.

The post office is 1 kilometre from Shahid's home and 2 kilometres from his school.

Bunty has read 27 books and Babli has read 34 books.

## Count to Subtract!

Dolma bought 4 dozen (48) bananas and gave one to each of her friends. 13 bananas were left. How many friends got a banana?

As you know, this can be found by counting forward from 13. It is easier to count in jumps of 10.
You can also use Kittu's home shown on page 29 to solve these problems.

48 - 13

10 + 10 + 10 + 5 = 35

So 48 - 13 = 35

56 - 37 =

10 + 10 + 1 = So, 56 - 37 =60 - 45 =

5 + 10 = So, 60 - 45 =80 - 59 =

++ =63 - 85 =

84 - 69 =

60 - 20 =

59 - 50 =

So, 80 - 59 =

## All the King's Horses....

Once there was a king who could count only up to 9. Up to what number can you count?

The king loved horses. But he could never count all of them. He kept them in such a way that he needed to count only up to 9 from each side.

How many horses in all did the king have?.

One day a visitor with 4 horses came there. It was getting dark so he wanted to stay there at night. But the horse-keeper was scared.

If the king saw these extra horses he would be very angry! The visitor said - do not worry. The king will never know. So he arranged the horses like this:

How many horses are there now?

At night the king came to count the horses. Along each side he counted 9 horses. Ah! That's fine - he said. Then he happily went to sleep.

In the morning the clever visitor tried another trick. He took out his own 4 horses. But he also ran away with some of the king's horses.
He left the king's horses standing in this way.

The silly king did not find any horse missing. Can you help him?

How many horses are now left?

How many of the king's horses were taken away?

(Based on a Tamil folk story from the book "Numeracy Counts!")

What numbers are we?

If you add us both you get 100.

The difference between us is also 100.
