Class 2 Maths Worksheet: Addition and Subtraction by Splitting with Answers

Every sum on this sheet is worked the way NCERT teaches it in Class 2 - by splitting the second number into tens and units and adding or subtracting in two steps, never by writing a column and carrying. Word problems at the end ask your child to apply the same method without the steps laid out.

Which is bigger: 56 + 30, or 56 + 3? Answer: 56 + 30, because adding 3 tens increases the number by 30, while adding 3 units increases it by only 3.

1)Without adding fully, which is bigger: 45 + 30, or 45 + 3? How do you know?
2)Which is bigger: 67 − 20, or 67 − 2? How do you know?
3)In the sum 58 + 34, why do we split 34 into 30 and 4 instead of some other way, like 20 and 14?
4)If 63 + 25 = 88, what is 63 + 26 without working it out fully? How do you know?
5)If 90 − 34 = 56, what is 90 − 35 without working it out fully? How do you know?
6)Which will give the bigger answer: 48 + 40, or 48 + 4? How do you know?
7)Meena says you can split either number in an addition sum, not just the second one. Is she right? Give an example to show why.
8)In 82 − 45, why must the number 45 be split, and not 82?
9)If 76 + 19 gives an answer close to 100, roughly what should the final answer be? How do you know?
10)Why does splitting never need carrying, but the column method sometimes does?

Answers

1) 45 + 30, because you are adding 3 tens (30) instead of 3 units (3), so the total increases by much more.
2) 67 − 2, because you are taking away only 2 units instead of 2 tens (20), so more of the original number stays.
3) Because 34 is made of 3 tens and 4 units, so splitting it that way matches its actual place value and keeps the steps simple.
4) 89, because 26 is just 1 more than 25, so the total is 1 more than 88.
5) 55, because 35 is just 1 more than 34, so 1 more is being taken away, making the answer 1 less.
6) 48 + 40, because adding 4 tens increases the number far more than adding 4 units.
7) Yes - for example, 34 + 57 can also be split as 30 + 4 + 57, first 57 + 30 = 87, then 87 + 4 = 91, the same answer either way.
8) Because 45 is the number being taken away - splitting it lets you subtract the tens first, then the units, from 82.
9) About 95, because 76 is close to 80 and 19 is close to 20, and 80 + 20 = 100, so the true answer should be just under 100.
10) Because splitting adds or subtracts the tens and units as separate, complete steps along a number line, instead of stacking digits in columns where a group of ten has to be carried across.

While your child works

If your own school years taught the column-and-carry method, resist correcting your child back to it - this splitting approach is the current NCERT method, not a shortcut.
Bundles of ten straws or ten-rupee coins make the splitting steps concrete if your child is guessing rather than working through them.
A wrong final answer with correct splitting steps still shows understanding - check the steps, not only the last number.

Questions parents ask

About this worksheet

Why is my child not carrying digits in these sums?

Because Class 2’s NCERT syllabus does not teach the carried column method yet - it teaches splitting the second number into tens and units instead. Carrying arrives in Class 4.

What if my child reaches the right answer a different way?

That is fine as a mental check, but ask her to also show the splitting steps on this worksheet, since that is what her class and exams currently expect.

Are any of these sums three-digit?

No, every number here stays within the Class 2 range of 1 to 100. Three-digit addition and subtraction belong to Class 3.

Does this Class 2 Maths worksheet come with answers?

Yes. Every exercise has a full answer key, and it prints on its own page at the end rather than beside the questions - so you can hand your child the sheet and keep the answers back. Some exercises also show one question already worked out, with the method rather than just the result, which is the part most answer keys leave out.

Is there a free printable PDF?

Yes, and there is no sign-up, no email and no account. The download button at the top of the sheet gives you the whole thing - all 76 questions across 7 exercises, plus the answer key - laid out to print on A4.

How long does this worksheet take?

About 30 minutes for 76 questions, though that is a guide rather than a target. It is designed to be split: the exercises are ordered so stopping halfway still leaves a complete piece of work, which matters more than finishing at this age.

Can I use it if my child is in a different class?

Often, yes - these topics are taught across several years and schools vary in when they arrive. Judge by the questions rather than the class on the label. If the first exercise is a struggle the level below is the better start, and the same topic at other levels is linked further up this page.
