Chapter 5

Ikra and her little sister, Samina, decide to make a drawing, but they are left with a single drawing sheet. Ikra wants to share the paper by dividing it in half, but Samina insists on having a bigger part of the paper. Ikra thought for a moment and proposed a solution.

One Half	One Quarter
	One Quarter

Let Us Discuss

Let Us Do

1. Samina has divided some figures into two parts. Colour the figures that are divided into halves correctly. How did you get the answer? 2. Divide the shapes into halves by drawing a line. 3. Divide these shapes into 4 equal parts/quarters. Think: How would we write the fraction for each part if we divided an object into 5 equal parts?

Many Ways to Make Halves and Quarters

Let Us Try

1. In how many different ways can you fold/cut a rectangular paper in two equal parts? Try it with a rectangular paper. 2. Now try to draw and show five different ways in which we can fold/cut a rectangle into four equal parts (1/4 or quarter). 3. Match the following parts with their corresponding wholes.

	I am 1/2 of
	I am 1/2 of
	I am 1/2 of
	I am 1/4 of

My Flower Garden

Idha has seeds of 5 different flowering plants—Rose, Mogra, Lily, Marigold, and Jasmine. She decides to plant them equally in her garden as shown in the picture. I have very few Lily seeds so I will plant Roses in two parts. Her revised plan is shown here.

Look at the garden and answer the questions. Look at the garden and answer the questions. Look at the garden and answer the questions.

Let Us Do

Make a flower garden with seven flowering seeds—Mogra, Marigold, Jasmine, Rose, Lily, Hibiscus, and Periwinkle?

Mogra	a) Marigold in one-seventh (1/7) and Rose and Hibiscus in three-sevenths (3/7) part each.	Rose
Marigold	b) Lily in three-sevenths (3/7), Marigold in two-sevenths (2/7) and Periwinkle in another two-sevenths (2/7).	Lily
Jasmine	c) Mogra in five-sevenths (5/7) part and Hibiscus in two-sevenths (2/7).	Hibiscus
Periwinkle

DREAM DOSA DESIGNER!!

Karan makes dosas differently. He makes dosas based on the customer’s choice with various toppings on a single dosa.

Customers can choose from the following toppings:
1. Classic potato
2. Spicy onion
3. Chilly paneer
4. Tangy tomato

Help Karan in making these special dosas.

Flavour of Dosa	Part of the Dosa
Classic potato	1/4
Spicy onion	1/4
Chilly paneer	1/4
Tangy tomato	1/4

Do It Yourself

Write the fractions for each of the toppings in the following dosas.

	1) Chilli paneer =_______
	2) Classic potato =_______

	1) Spicy onion =_______
	2) Tangy tomato =_______

	1) Tangy tomato =_______
	2) Classic potato =_______
	3) Spicy onion =_______

	1) Tangy tomato =_______
	2) Classic potato =_______
	3) Spicy onion =_______

Now you can make different dosas based on demand.

Now let us try to find fractions for the situations given below. Circle the appropriate parts in the pictures.

1. There are 12 cookies. What fraction of cookies will each get if the number of children are as follows:
a) 3 children
b) 6 children
c) 2 children
d) 4 children

5. Simran calls her school friends for her birthday party. 1/3 of her friends receive a hairband as their return gift. Place hairbands on 1/3 of her friends.

6. Draw flowers in 1/5 of the given number of pots.

Let Us Do

1. Take a rectangular piece of paper and fold the paper into three equal parts and then unfold it.
2. Colour one of the three equal parts as shown in the image.
3. Fold the paper back into three equal parts like before, and then fold it in half.
4. Observe the colored part. What is the fraction for the shaded part now? What does this mean?
5. Fold the paper again and check how the coloured part changes.
6. Write down what fraction you observe after each fold. 1/3 = 2/6 = _____ = ______=_____

Let Us Try

Take another piece of paper and try the same starting with two equal parts, and halving every time. Share the findings with your friends.

1/2 = 2/4 = _____ = ______=_____

Let Us Discuss

Observe the fraction chart and discuss the following questions. You may use your fraction kit also to explore the answers.

1. How many 1/4 s are equal to 1/2 ?
____________________________

2. Is 2/3 less than or greater than 1/2 ?
____________________________

3. Ten pieces of 1/10 make a complete whole.
Is this statement true?
____________________________

4. Three pieces of 1/6 are equal to two pieces of 1/8.
Is this true?
____________________________

5. How many pieces of 1/8 make 1/4 ?

6. Find the pieces that you can put together to make another bigger piece.

Let Us Do

1. Bablu is playing with square shapes. He wants to cut them in such a way that each piece is equal in size. Circle the squares which have been cut into equal parts. Write the fraction for the shaded part, whenever possible. 2. Check if the children’s claim below about the shaded parts of each of the pictures is correct. Circle the ones which you think are correct, cross out the ones which are not correct. You can draw additional lines to make the parts equal. Discuss your thinking.

Ameena says: 1/3 Kishore says: 1/4	Perry says: 1/6 Kunj says: 1/3	Balu says: 1/5 Gita says: 1/4

3. Identify the fractions represented by the coloured parts in the given pictures.

__________	__________	__________
