Joyful Mathematics 2 — Give and Take. Totalling rupee amounts uses the same tens-and-ones addition skills practised with buying and selling stories.
What you'll learn
- To add rupee amounts the same way as adding numbers, using the ₹ symbol.
- To add round amounts (₹20 + ₹30) and two-digit amounts (₹24 + ₹35).
- To solve simple money word problems with two or three amounts.
Key concepts
Verbal: Adding money is just adding numbers — remember to write ₹ in the answer.
Symbolic: ₹24 + ₹35 → ones: 4+5=9, tens: 2+3=5 → ₹59.
Level 1 — Round amounts
₹30 + ₹40 = ₹70.
Level 2 — Two-digit amounts
₹42 + ₹16 = ₹58.
Level 3 — Three amounts (savings over weeks)
₹18 + ₹24 + ₹15 = ₹57.
Worked example
Ramu has a ₹24 note and a ₹35 note. What is the total?
Step 1 — Add ones: 4 + 5 = 9
Step 2 — Add tens: 2 + 3 = 5
Answer: ₹59
Common mistakes
| Mistake | Why | Fix |
|---|---|---|
| Forgetting the ₹ symbol in the answer | Treating it like plain numbers | Always write ₹ before the total |
| Adding tens and ones incorrectly | Column mix-up | Add ones to ones, tens to tens |
| Missing one amount in a three-part sum | Rushing | List all amounts before adding |
Quick check
- ₹20 + ₹50 = ?
- ₹33 + ₹25 = ?
- Priya saved ₹18, ₹24, and ₹15 over 3 weeks. Total saved?
Stretch: Add ₹47 + ₹38 (this needs regrouping — carry the extra ten).
Revision tip: Practise with play-money notes, laying them out before adding.
