Let us do it on Ginladi!
A. 25 + 12 =
Count 12 ahead of 25
Result: 37
B. 57 + 34 =
Count ahead of 57
Let us understand this way.
57 + 34 = 57 + 30 + 4
87 + 4 = 91
C. 24 + 43 =
We can write 24 + 40 + 3 = 64 + 3 = 67
We can get the number 43 in another way: 20 + 20 + 3
It is difficult to count the beads of ginladi every time. Let me write the numbers in place of beads.
Now add numbers on the number line.
I am calling this a number line.
A. 23 + 14 =
B. 24 + 16 =
C. 11 + 22 =
Read the number line and fill the boxes.
A. 22 + = 38
B. 18 + =
C. + =

Playing with Blocks
Mahi has some blocks. Isha came with her blocks to play. Let us help them in finding how many blocks they have in total.
| Person | Blocks | Total |
|---|---|---|
| Mahi's Blocks |  2 tens 3 ones |
23 |
| Isha's Blocks |  3 tens 8 ones |
38 |
| Total |  5 tens 11 ones |
 61 (6 tens 1 ones) |
Let us find the total number of blocks.
 3 tens 6 ones 4 tens 7 ones |
 7 tens 13 ones 8 tens and 3 ones |
 80 + 3 = 83 |
4 tens 5 ones 4 tens 9 ones |
||
 5 tens 8 ones 3 tens 2 ones |
||
 8 tens 1 ten 4 ones |
||
 2 tens 6 ones 4 tens 8 ones |
Mahi, do you
know, we can add
without
counting all
the blocks again
and again?
Oh really, Isha!
Can you show
me how?

Let us Do
- A. Rahim made 43 runs in one match and 58 runs in another match. How many runs he made in the two matches together?
- B. Simarpreet had 12 colour pencils. Her mother gifted her 36 more colour pencils. How many total colour pencils does she have now?
- C. Heena collected 34 red marbles and 57 blue marbles. How many total marbles does she have now?
- D. Sarika spent ₹56 in the fair, while Manish spent ₹35 in the fair. What is the total money they both spent in the fair?
- E. There are 36 men and 47 women in the bus. How many people are there in the bus?
Let us Count Diyas
I made 75 diyas in a day and sold 35 out of them. Let me count how many diyas are left now? 1, 2, 3...
I have another way of doing it. We can draw as many lines as the number of diyas left. Interesting! Is there any other way to find out? Yes, we can do this on ginladi too.
I count 75 first and then I will go 35 steps backward.
That means if we take away 35 from 75, then the answer will be 40.
75 – 35 = 40
If we have 32 diyas in the morning and 12 diyas are sold by the evening. How many diyas are left?
On taking away 12 from 32, we get 20.
32 − 12 = 20We can also use the ginladi to find the answers of the following.
-
A. Take away 9 from 18
18 − 9 =
-
B. Take away 8 from 12
12 − 8 =
-
C. Take away 18 from 30
30 − 18 =
-
D. Take away 14 from 23
23 − 14 =
-
E. Take away 17 from 26
26 − 17 =
Yesterday,
we counted left
out diyas on the
ginladi.
Tell me how you did
it? But,
I don’t have a
ginladi at my home.
Let us make a
ginladi on the
paper then.
If I want to
take away
15 from 19,
I count till
19 first,
then move 15
steps backward.
19 − 15 = 4
I have another
way of doing
subtraction on
the number
line.
We can directly
jump back 10 steps
and then go 5 steps
back to reach 4.

Discuss with children about subtracting zero and subtracting the number with itself by taking examples from daily life situations, like, spending all money or spending no money.
Playing with Blocks
I have 45 blocks.
I give 12 to

Decorating with Garlands
Jyoti, can I have 1 and 8 ?
I have only 6 loose I think I should open a. Now I can give 8 to mummy.

Now, Jyoti has 28 flowers in all. She gives 5 to her friend. Help Jyoti to find out how many flowers is she left with?
Now, Jyoti has 54 flowers in all. She gives 28 to her mother. How many flowers is she left with?
Oh! I need to open one garland. Then I will have 4 garlands and 14 flowers, from it I can give 8 flowers.
14 − 8 = 6
I am left with 2 garlands and 6 flowers or 26 flowers in all.
Jyoti has 73 flowers in all. She gives 47 to her mother. How many flowers is she left with?
| Garlands | Flowers | |

Skip the Rope
Aman and Avni are playing 'skip the rope'. Both have to complete 20 skips. A skip can be counted when the rope passes under the feet. They will get two chances to skip. If one misses any skip in the first time then they will get one more chance to complete 20 skips.
- A. Aman skipped 14 times in the first chance. How many more skips he has to make to complete 20 skips?
20 - 14 =
14 + ____ = 20
- B. Avni skipped 12 times in the first chance. How many more skips she has to make to complete 20 skips?
20 − 12 = ____
12 + ____ = 20
