Money: Adding and Subtracting AmountsActivities & Teaching Strategies
Working with real coins and notes makes money calculations come alive for Class 3 learners. When students physically handle amounts, they move beyond abstract symbols to see how rupees and paise combine and separate during transactions. This hands-on practice builds both skill and confidence in everyday money tasks.
Learning Objectives
- 1Calculate the total cost of multiple items by adding their individual prices in rupees and paise.
- 2Determine the correct change to be received after a purchase by subtracting the cost from the amount paid.
- 3Compare different combinations of currency notes and coins to find the most efficient way to pay for an item.
- 4Construct a simple shopping list for a given scenario and calculate its total cost accurately.
- 5Explain the importance of accurate money calculations for making informed purchasing decisions.

Role Play: Mini Market Shop
Divide class into shopkeeper and buyer roles with priced fruits and vegetables using play rupees and paise. Buyers select 3-4 items, add totals aloud, and receive change. Switch roles after 10 minutes, with shopkeepers noting calculations on charts.
Prepare & details
Analyze the most efficient way to add different amounts of money.
Facilitation Tip: During Role Play: Mini Market Shop, circulate with a small basket of coins to nudge pairs who forget to exchange ₹1 coins for 100 paise when borrowing during subtraction.
Setup: Adaptable to standard classroom seating with fixed benches; fishbowl arrangements work well for Classes of 35 or more; open floor space is useful but not required
Materials: Printed character cards with role background, objectives, and knowledge constraints, Scenario brief sheet (one per student or one per group), Structured observation sheet for students watching a fishbowl format, Debrief discussion prompt cards, Assessment rubric aligned to NEP 2020 competency domains
Pairs: Shopping List Total
Pairs draw a shopping list of 5-6 household items with prices. They calculate total cost two ways: column addition and mental grouping. Discuss which method is faster and share with class.
Prepare & details
Construct a shopping list and calculate the total cost.
Facilitation Tip: When Pairs: Shopping List Total work on their lists, remind students to align rupee and paise columns vertically in their notebooks to avoid place-value errors.
Setup: Adaptable to standard classroom seating with fixed benches; fishbowl arrangements work well for Classes of 35 or more; open floor space is useful but not required
Materials: Printed character cards with role background, objectives, and knowledge constraints, Scenario brief sheet (one per student or one per group), Structured observation sheet for students watching a fishbowl format, Debrief discussion prompt cards, Assessment rubric aligned to NEP 2020 competency domains
Whole Class: Change Calculation Race
Project purchase scenarios on board, like ₹20 note for ₹14.75 bill. Teams race to board, subtract, show change with coins, and explain steps. Correct teams earn points.
Prepare & details
Justify the importance of accurate money calculations in daily life.
Facilitation Tip: For Change Calculation Race, display a large subtraction model on the board so students can see how borrowing from ₹1 turns into 100 paise before subtracting.

Individual: Money Puzzle Sheets
Students solve worksheets matching amounts to coin combinations, then add or subtract pairs. They colour correct answers and self-check with answer keys before sharing one puzzle with neighbour.

Teaching This Topic
Teachers should start with concrete objects before moving to symbols, because research shows children aged 8-9 grasp money best through physical handling. Avoid rushing to algorithms; instead, let students verbalise steps while handling coins so their internal logic matches the action. Include frequent peer checks so children correct each other’s mistakes in real time.
What to Expect
By the end of these activities, students will add and subtract rupees and paise accurately in shopping scenarios, explain their regrouping steps clearly, and verify totals using play money or drawings. They will also justify change amounts and suggest efficient methods like grouping coins before adding.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Pairs: Shopping List Total, watch for students who add only rupee parts first and leave paise aside.
What to Teach Instead
Ask pairs to sort play coins into rupee and paise piles, then combine paise first and physically carry over to rupees if needed before adding totals. Hold a quick group discussion where volunteers show their regrouping on the board.
Common MisconceptionDuring Role Play: Mini Market Shop, watch for children who subtract paise directly when the paise part is smaller, leading to negative paise.
What to Teach Instead
Give each shopkeeper and customer a ₹1 coin to exchange for 100 paise whenever borrowing is needed; let students repeat the transaction until the correct change is found. Peers at adjacent stalls can verify the result before moving on.
Common MisconceptionDuring Whole Class: Change Calculation Race, watch for students who confuse addition totals with subtraction change calculations in word problems.
What to Teach Instead
Label three stations clearly with green ‘Add’ and red ‘Subtract’ signs. Students rotate and solve only the labelled tasks, then justify their choice of operation to the next pair before checking answers together.
Assessment Ideas
After Pairs: Shopping List Total, give each pair a new list with three items whose total you know. Ask them to show the calculation on mini whiteboards and hold up the answer; scan for correct regrouping of paise and rupees.
During Role Play: Mini Market Shop, collect each student’s final change card after they calculate payback from a ₹50 note for a ₹25.75 purchase. Keep a small set aside to review common errors before the next session.
After Whole Class: Change Calculation Race, ask students to share efficient methods they discovered during the race. Listen for evidence of grouping coins first or using place-value language when explaining totals.
Extensions & Scaffolding
- Challenge early finishers to create a balanced shop menu under ₹100 where the total is exactly ₹99.99 using no more than five items.
- Scaffolding for strugglers: Provide a template with separate boxes for rupees and paise and pre-printed coin images to glue while calculating.
- Deeper exploration: Invite students to research and present how shopkeepers in their area round off paise to the nearest rupee during daily transactions.
Key Vocabulary
| Rupee (₹) | The basic unit of Indian currency. It is represented by the symbol ₹. |
| Paisa (p) | A smaller unit of Indian currency, where 100 paise make 1 rupee. It is often used for smaller amounts. |
| Addition | The process of combining two or more amounts to find their total sum. This is used to find the total cost of items. |
| Subtraction | The process of taking away one amount from another to find the difference. This is used to calculate change. |
| Change | The amount of money returned to a customer after they pay more than the cost of their purchase. |
