Playing with a Grid
Solution:
Yes, 1/3 is seen in all the grids. The marked portion in the grids below represents 1/3.
Is 1/3 equal to 2/6? Let us find out.
Look at the picture and identify the fractions.
Are there two different ways to write the fraction represented by the shaded part? Yes
Do you see that 1/3 = 2/6? Yes. These are called ‘equivalent fractions’.

Q. When a 1/2 piece is broken into 2 equal parts, each part is a 1/4 piece. 2 pieces of 1/4 are equal to 1/2.
What else is equivalent to 1/2?
Solution:
Textbook Page 19 – 20
Let Us Do
1. In groups of 3 or 4, find different ways of making a whole with different fraction pieces from your kit. Write the equivalent fractions for the following that you may find in the process.
Do you see how to generate equivalent fractions for any given fraction? Discuss in class.
Solution:
Hence, to generate equivalent fractions, we have to multiply (or divide) the numerator and denominator by the same number.
2. Find the following using your kit. You can also shade and check by shading the following. The first one is partially done for you
Solution:
B.
C.
3. Do as instructed using your fraction kit.
• Make a whole using only 1/6 and 1/12 pieces.
• Make a whole using 1/12 , 1/4, and 1/2 pieces.
• Make a whole using any five pieces of the same size.
• Make a whole using any seven pieces.
Play in a group with this kit and find other interesting combinations to make a whole. Write or draw your findings.
Solution:
We found that if each piece is 1/n, then n pieces will always make a whole.

Q. Divide the wholes given below into more equal parts and find fractions equivalent to 1/3. Write them in the boxes below the images.
Solution:
Q. Do you see any pattern in all the equivalent fractions that you found?
Solution:
Equivalent fractions are made by multiplying both the numerator and denominator of 1/3 by the same number.
Q. How do you know when a fraction is equivalent to another? Discuss in class.
Solution:
Two fractions are equivalent if you can get one from the other by multiplying or dividing both the numerator and denominator by the same number.
Q. The below pictures show 2/5 of a whole. Find the different fractions that are equivalent to 2/5 and write your fractions below each image.

Raman’s sister Radhika took 6 pieces of 1/2 paratha. How many parathas did she eat?
Q. Dadiji had 7 pieces of 1/2 parathas. How many parathas did she eat? Find out.
Solution:
Q. Raman ate 6 pieces of 1/2 paratha, Dadaji ate 7 pieces of 1/2 paratha, and Baba ate 5 pieces of 1/2 paratha. How many parathas did each of them eat? Use the number line to find the answer.
Solution:
Q. How many parathas were made on this day? Find out.
Solution:
Q. Raman ate 7 pieces of 1/4, Radhika ate 6 pieces of 1/4, Maa ate 8 pieces of 1/4, Dadiji ate 10 pieces of 1/4, and Baba ate 12 pieces of 14 paratha. Use a number line to find out how many parathas were eaten by each of them.
Solution:

Let Us Do
1. Use parathas and number lines to show the following fractions in your notebook.
Solution:
2. Circle the fractions that are greater than one (whole). How do you know? Discuss your reasoning in the class.
Solution:
7/9 → less than 1
3/9 → less than 1
7/11 → less than 1
9/4 → greater than 1
9/4 → greater than 1
2/5 → less than 1
5/4 → greater than 1
7/3 → greater than 1
5/7 → less than 1
4/9 → less than 1
2/3 → less than 1
13/11 → greater than 1
12/5 → greater than 1
12/8 → greater than 1
A fraction is greater than one when the numerator is more than the denominator.
