NCERT Revision Notes for Class 2 Maths Chapter 7: Rani’s Gift – Free PDF Download

Chapter 7 of Class 2 Maths, Rani’s Gift, uses a gift-giving story to build addition and subtraction skills with two-digit numbers, including simple regrouping (carrying and borrowing) as numbers get a little bigger than in Class 1.

Last Updated: September 23, 2026

Key Concepts

Adding two-digit numbers: adding tens with tens and ones with ones, such as 23 + 15 = 38.

Regrouping in addition (carrying): when the ones digits add up to 10 or more, one ten is carried over to the tens column, such as in 27 + 15 = 42.

Subtracting two-digit numbers: subtracting ones from ones and tens from tens, such as 48 − 23 = 25.

Regrouping in subtraction (borrowing): when the ones digit being subtracted is bigger than the ones digit on top, one ten is borrowed from the tens column.

Number stories: real-life situations, like giving and receiving gifts, written as addition or subtraction number sentences.

Worked Examples

Example 1

Rani has 24 stickers. Her friend gives her 15 more. How many stickers does she have now? 24 + 15 = 39 stickers.

Example 2

Add 27 + 15 using regrouping. Ones: 7 + 5 = 12, write 2 and carry 1 ten. Tens: 2 + 1 + 1 (carried) = 4. So 27 + 15 = 42.

Example 3

Subtract 42 − 18 using regrouping. Since 2 ones is less than 8 ones, borrow 1 ten from the tens place: 12 − 8 = 4 ones, and 3 − 1 = 2 tens. So 42 − 18 = 24.

Quick Recap

• When adding two-digit numbers, add ones to ones and tens to tens.
• If the ones add up to 10 or more, carry 1 ten to the tens column.
• When subtracting, if the top ones digit is smaller, borrow 1 ten from the tens column.
• Gift-giving and receiving stories can be turned into addition or subtraction number sentences.
• Checking a subtraction answer by adding it back to the number subtracted helps confirm it is correct.

Common Mistakes to Avoid

• Forgetting to carry the extra ten when the ones digits add up to 10 or more.
• Subtracting the smaller digit from the larger one in the wrong column instead of borrowing correctly.
• Adding or subtracting the tens and ones columns in the wrong order.
• Forgetting to reduce the tens digit by 1 after borrowing in subtraction.
• Misreading the word problem and using addition instead of subtraction, or the other way around.

Home Practice Tips

• Use bundles of ten straws or ice cream sticks along with loose ones to physically show carrying and borrowing.
• Practise a few two-digit addition and subtraction sums daily, mixing regrouping and non-regrouping questions.
• Make up simple gift-themed word problems together, like sharing sweets or toys.
• Ask the child to check subtraction answers using addition.
• Use play money in tens and ones to practise adding and subtracting small amounts.

Frequently Asked Questions

Q1. What is regrouping, and why is it needed in this chapter?
Regrouping means carrying extra tens in addition or borrowing a ten in subtraction when the ones digits do not add or subtract simply, and it is needed to correctly solve many two-digit sums.

Q2. How can I help my child understand carrying in addition?
Use physical bundles of ten objects to show that once the ones reach 10, they form one full new ten that moves to the tens column.

Q3. Why is borrowing sometimes confusing for children?
Borrowing involves temporarily reducing the tens digit and adding 10 to the ones digit, which is a new and less intuitive idea compared to simple subtraction without regrouping.

Q4. How can I check if my child’s subtraction answer is correct?
Add the answer back to the number that was subtracted; if the result matches the original number, the subtraction was done correctly.

Q5. What comes after this chapter in the addition and subtraction sequence?
Later chapters and classes build on this by introducing larger numbers, three-digit addition and subtraction, and more complex regrouping situations.
