Give and Take
I start from room 2. I add 10 to 2 to reach room 12 and paint
it. To add 10 to 2, we can go all the way to the right to 10.
Then up to 11, and one step right to 12.
This is one way to go from 2 to 12.
Is there a shortcut? Of course! Follow me.
We can jump up one row.
A jump from 2 to 12 is like taking  steps.

 Now try one jump up from 14.
14 + 10 =   24   .
Colour this room.
 How will I go from 22 to 41? Jump from
22 to 42.
Then one step left. We can write it like this.
22 + 20 = 42
42 –  1  = 41
How many steps did I go in all? 
You could also go this way:
From 22 take one step left to 21.
Then two jumps up to 41.
22 –  1  = 21
21 + 20 = 41
Find My Food
Try these on Kittu's home:
Hey! I have something more interesting for you.
Ma told me, there are sweets to eat in some rooms.
Help me find that room. The answers from the next page will
help you find that room. Mark them in my home.
a) 10 less than 34 is .
b) 53 – 20 = 
c) 11 more than 31 is .
The 10×10 number grid is a useful aid for adding and subtracting two-digit numbers. Children
should be encouraged to try these operations mentally using the grid as often as possible.

Is there a
shortcut to
do this?
66  –            =  11
E.g.,   47  =   37  +  10
37 + 9  =
65 – 30 =
Will it be easier
to go to 46 + 20
first?
  98 =           + 50
36 =           +  9
45  +            =  99
+  26 = 75
40 +           = 76
  57 –            = 20 – 21 = 35
= 87 – 30
  = 46 + 21
Similarly how
will you do this?

Anisha bought apples for 37
rupees. Raja bought bananas
for 21 rupees. The woman
selling fruits said:
37 is 30 and 7
21 is  20 and 1
So 37 and 21 make 58.
We break 26 into 20 + 6
and 43 into 40 + 3.
Then it's easy:
we add 20 + 40 and
3 + 6 !
 Let us also try. Look at this sum.
The first two,
I can do.
How did she
add 37 and 21
so fast?
The answer is 69.
