Q1. Share your observations about the different pieces and the whole.
Answer Here is what the fraction kit shows.
The fraction kit laid out in rows, from the whole down to tenths.
- All the pieces in one row are of the same size.
- Every row, put together, covers the whole strip exactly.
- The 1/2 piece is the biggest piece; the 1/10 piece is the smallest.
- As we go down, the pieces become more in number and smaller in size.
2 pieces of 1/2 = 1 whole
4 pieces of 1/4 = 1 whole
10 pieces of 1/10 = 1 whole
Why it happens: Each row is the same whole cut into a different number of equal parts, so more parts always means smaller parts.
Q2. Take any two different pieces of the fraction kit and compare them. Discuss which one is smaller and why.
Answer Sample answer: Take the 1/4 piece and the 1/8 piece. The 1/8 piece is smaller.
The 1/4 piece placed above two 1/8 pieces.
Put the 1/8 piece on the 1/4 piece
It covers only part of it
In fact 2 pieces of 1/8 cover 1 piece of 1/4
Why it happens: For 1/8 the whole was cut into 8 equal parts and for 1/4 into only 4. Cutting the same whole into more parts makes each part smaller.
Try This: Compare 1/3 with 1/6, and 1/5 with 1/10. Each time the piece with the bigger number below the line is the smaller piece.
Q3. Sumedha noticed that when a whole is equally divided in a larger number of parts, each part gets smaller. Do you agree with Sumedha?
Answer Yes, Sumedha is right.
The same roti cut into 2, 4 and 8 equal parts. One part is coloured each time.
Same roti, 2 parts → each part = 1/2
Same roti, 4 parts → each part = 1/4
Same roti, 8 parts → each part = 1/8 — the smallest
Why it happens: The whole never changes. If it has to be shared among more parts, every part must take less.
Q4. Sumedha says, “When I join 5 pieces of 1/5, it makes a whole dhokla.” Try to do it yourself with your fraction kit.
Answer Sumedha is right. Five pieces of 1/5 make one whole.
Four of the five one-fifth pieces are drawn above the whole strip; the fifth one completes it.
- Take out all five 1/5 pieces from your kit.
- Place them end to end in a line.
- Put the whole strip below them.
- The five pieces cover the whole strip exactly, with nothing sticking out.
1/5 + 1/5 + 1/5 + 1/5 + 1/5 = 1 whole
Why it happens: 1/5 means the whole was cut into 5 equal parts, so putting all 5 parts back gives the whole again.
Q5. Sumedha says that this part is one-third of the complete whole. Why is she saying so?
Answer Because the whole dhokla was cut into 3 equal pieces and she is holding 1 of them.
The whole dhokla cut into three equal pieces, and one single piece beside it.
Dhokla cut into 3 equal pieces
Sumedha holds 1 piece
1 out of 3 equal pieces = 1/3 (one-third)
Why it happens: The number below the line counts the equal pieces of the whole, and the number above counts how many we have taken.
Check it yourself: The two pieces left on the plate are also 1/3 each. All three pieces together make the whole dhokla.
