All 66 questions of the chapter (textbook pages 64 – 81) are answered below, in the order of the book – in-text questions, activities and the end-of-chapter exercises. Each answer is written the way you would write it in the exam.

In-text Questions — Page 64The triangular toran at the mela

Q1How many triangles are there in a line of triangular toran?
4 lines1 line1010101010
The triangular toran at the mela. Each bunch under the last line holds ten triangles.
Answer

One line of the toran has 50 triangles.

One line = 10 + 10 + 10 + 10 + 10
= 50 triangles
Q2Try counting all the triangles.
4 lines1 line1010101010
The triangular toran at the mela. Each bunch under the last line holds ten triangles.
Answer

There are 250 triangles in all.

  1. Each line has 50 triangles.
  2. Two lines make 50 + 50 = 100.
  3. Four lines make 100 + 100 = 200.
  4. One line is left: 200 + 50 = 250.

In-text Questions — Page 65Bangles, toffees and the toran

Q1Guess how many bangles there are. Try counting the total number of bangles.
Figure
Bangles hanging on seven rods. Each rod carries four bunches.
Answer

There are 280 bangles.

  1. Each bunch has 10 bangles.
  2. One rod holds 4 bunches, so one rod has 40 bangles.
  3. Count the bunches in tens: 10, 20, 30 … 100, 110 … 200, 210 … 270, 280.
Q2Guess how many toffees there are in the boxes. Count and check.
Figure
Three jars of toffees. Each row inside a jar holds ten toffees.
Answer

There are 298 toffees in the three jars.

Jar 1 = 100
Jar 2 = 100
Jar 3 = 98
100 + 100 + 98 = 298

Each row inside a jar holds ten toffees. Two jars are full, the third is two short.

Q3Jojo has 2 toffees in his hand. How many toffees are there altogether?
Figure
Three jars of toffees. Each row inside a jar holds ten toffees.
Answer

Altogether there are 300 toffees.

298 + 1 = 299
299 + 1 = 300
Q4How many more triangles to make 300?
4 lines1 line1010101010
The triangular toran at the mela. Each bunch under the last line holds ten triangles.
Answer

We need 50 more triangles.

250 + 50 = 300

That is one more line of toran, because one line has 50 triangles.

Q5How many bangles less than 300?
Figure
Bangles hanging on seven rods. Each rod carries four bunches.
Answer

The bangles are 20 less than 300.

280 + 20 = 300
So 300 – 280 = 20

Two more bunches of ten would make three hundred.

Q6Which is more: bangles or triangles?
Figure
Bangles hanging on seven rods. Each rod carries four bunches.
4 lines1 line1010101010
The triangular toran at the mela. Each bunch under the last line holds ten triangles.
Answer

The bangles are more.

Bangles = 280
Triangles = 250
280 is more than 250

Let us Play — Page 69Flag game

Q1Why does the flag point to the right?
200201202203204205206207208209210
Jojo’s first guess, 205, with the flag beside it.
Answer

Because the hidden number is more than the guess.

Jojo guessed 205. The flag at 205 points to the right. So the number is bigger than 205.

Q2Why does the flag point to the left?
200201202203204205206207208209210
The second guess, 208, with both flags.
Answer

Because the hidden number is less than the guess.

Jojo then guessed 208. The flag at 208 points to the left. So the number is smaller than 208.

Now we know the number is more than 205 and less than 208.

Q3Now, try and play with your friends, and guess the number.
200201202203204205206207208209210
All three flags after the guesses 205, 208 and 206.
Answer

In the book’s game the hidden number is 207.

  1. 205 is wrong, flag points right: more than 205.
  2. 208 is wrong, flag points left: less than 208.
  3. 206 is wrong, flag points right: more than 206.
  4. Only 207 is left.

Numbers on a line — Page 70The next hundred number

Q1Tell Teji, Jojo and Bholu what will be the next hundred number. Write it on the number line below.
0100200300
Hundreds on a number line. The last box is empty.
Answer

The next hundred number is 400, four hundred.

100, 200, 300, 400

Each jump on this line is one hundred more.

The next hundred number written in.
Q2Can you show the number using matchsticks?
0100200300
Hundreds on a number line. The last box is empty.
Answer

Yes. Take 4 bundles of a hundred matchsticks.

400 = 4 H + 0 T + 0 O
= 100 + 100 + 100 + 100

No small bundles and no loose sticks, so tens and ones are 0.

Four hundred shown with four bundles of a hundred matchsticks.

Q3Tell how far is 387 from 400: ……………..
370380387390400387
A number line from 370 to 400 with a jump drawn on it.
Answer

387 is 13 away from 400.

387 + 3 = 390
390 + 10 = 400
3 + 10 = 13

Jump in small steps to the next ten, then take one big jump of ten.

370380387390400387+3+10
From 387 to 390 is 3 steps; from 390 to 400 is 10 steps.

Q1How many pieces of mysore pak are in one tray? ……………..
Figure
Farooq chacha’s counter. Each open tray has ten rows of ten places; the packed trays below are marked 100.
Answer

A full tray holds 100 pieces. The open tray on top has 45 pieces.

4 lines of 10 = 40
1 line of 5 = 5
40 + 5 = 45
Q2How many pieces of mysore pak are there in total? ……………..
Figure
Farooq chacha’s counter. Each open tray has ten rows of ten places; the packed trays below are marked 100.
Answer

In all there are 445 pieces of mysore pak.

4 packed trays = 100 + 100 + 100 + 100 = 400
Open tray = 45
400 + 45 = 445
Q3How many laddoos does chacha have in the trays? ……………..
Figure
Farooq chacha’s counter. Each open tray has ten rows of ten places; the packed trays below are marked 100.
Answer

Chacha has 469 laddoos.

4 full trays = 400
Open tray = 69
400 + 69 = 469

The open tray has 10 lines of 7 laddoos, but the last line has only 6. So it has 70 – 1 = 69.

Q4How many dhoklas does chacha have? ……………..
Figure
Farooq chacha’s counter. Each open tray has ten rows of ten places; the packed trays below are marked 100.
Answer

Chacha has 470 dhoklas.

4 packed trays = 400
Open tray = 70
400 + 70 = 470

The dhokla tray is filled just like the laddoo tray.

Q5Chacha is going to fill the tray with more laddoos. How many more laddoos will make the tray full? ……………..
Figure
Farooq chacha’s counter. Each open tray has ten rows of ten places; the packed trays below are marked 100.
Answer

31 more laddoos will fill the tray.

A full tray = 100
69 + 1 = 70
70 + 30 = 100
1 + 30 = 31

One place in the laddoo tray is empty, and 3 more lines of ten are empty.

Q6How many total laddoos will he have after the last tray is full? ……………..
Figure
Farooq chacha’s counter. Each open tray has ten rows of ten places; the packed trays below are marked 100.
Answer

He will have 500 laddoos.

469 + 31 = 500

Then he has five full trays: 100 + 100 + 100 + 100 + 100 = 500. Five hundred.

Q7Mark the following numbers on the number line below: 423, 487, 438, 476. Mark Five Hundred (500) on this number line!

The same four pieces with every house named.
Q3Who am I? I have digits 9, 1 and 5. I am less than 200. I have 9 ones. Which number am I?
Answer

The number is 159.

  1. It is less than 200, so the hundreds digit must be 1.
  2. It has 9 ones, so the last digit is 9.
  3. Only 5 is left, and it goes in the tens place.
1 hundred + 5 tens + 9 ones = 159
Q4Who am I? I am a 3-digit number. I have only digits 4 and 0. Which number am I?
Answer

I can be 400, 404 or 440. Any one is correct.

A 3-digit number cannot begin with 0, so the hundreds digit must be 4.

Q5Who am I? I am greater than 300 but less than 400. I have no tens. My ones and hundreds digits are the same. Which number am I?
Answer

The number is 303.

  1. It lies between 300 and 400, so the hundreds digit is 3.
  2. It has no tens, so the tens digit is 0.
  3. The ones digit is the same as the hundreds digit, so it is 3.
300 + 0 + 3 = 303
