2. Cross (7) out the objects to subtract and find the answer. One has been done
for you.

(a) (b) (c)

7 – 2 = 5 6 – 1 = 4 – 1 =

(d) (e) (f)

8 – 4 = 3 – 2 = 5 – 3 =

Subtraction: backward counting

Kiyara has 15 toys. She gave 9 toys to her brother Kavi.

Kavi: How many toys are left with you now?

Kiyara: 6 toys

Kavi: How?
Kiyara: I subtracted the toys given to you from the total number of toys.

You can count backwards to subtract. Start from 15 and count back 9 steps as follows:

15 14 13 12 11 10 9 8 7 6

1 2 3 4 5 6 7 8 9

Similarly, to subtract 5 from 12, we start with the bigger number 12 and count
backwards 5 steps.
Note
12 11 10 9 8 7 Subtraction is opposite of
addition. In addition, we
1 2 3 4 5 count forward but in case
of subtraction, we count
Thus, 12 – 5 = 7 backward.
