Activity 01
Role-Play: Market Stall Exchange
Divide class into small groups with one shopkeeper per group. Shopkeeper displays 3-4 priced items using tags. Customers choose items, add totals mentally or with fingers, pay with play money, and receive change. Rotate roles every 10 minutes and discuss transactions.
Why do we use money instead of just trading toys for snacks?
Facilitation TipDuring Market Stall Exchange, circulate and ask each pair to explain their total cost and change aloud to reinforce verbal reasoning.
What to look forPresent students with pictures of 2-3 items with prices clearly marked (e.g., a pencil for 5 rupees, an eraser for 3 rupees). Ask them to write down the total cost and then, if they pay with a 10 rupee note, calculate the change they should receive.

Activity 02
Coin Match: Equivalence Game
Prepare cards with amounts like 10 rupees and sets of coins. Pairs draw cards and find matching combinations, such as five 2-rupee coins or two 5-rupee coins. They record findings and explain to the group why values match.
How can different combinations of coins equal the same total value?
Facilitation TipIn Coin Match, circulate and ask students to justify why a set of coins equals a certain amount, using phrases like 'because five 1-rupee coins equal 5 rupees'.
What to look forShow students a picture of an item costing 15 rupees. Ask: 'If you have one 10 rupee note and two 2 rupee coins, do you have enough money? How do you know?' Encourage them to explain their reasoning by calculating the total money they have.

Activity 03
Change Jar: Total Calculation
Teacher announces item prices and payment amount for the whole class. Students suggest change using a shared coin jar on the board. Demonstrate by removing coins step-by-step, then let volunteers lead next rounds.
What information do we need to know if we have enough money to buy something?
Facilitation TipWhile playing Change Jar, check students’ totals by asking them to count coins aloud before recording the answer.
What to look forGive each student a card with a scenario, such as: 'You bought a fruit for 8 rupees and paid with a 10 rupee note.' Ask them to write down the amount of change they should get back. Collect these as students leave the class.

Shopping Budget: Enough Money Check
Give each student a shopping list of 2-3 items with prices and a set of play coins. They calculate total cost, compare to coins, and decide if they can buy. Share results and adjust budgets in pairs.
Why do we use money instead of just trading toys for snacks?
Facilitation TipDuring Shopping Budget, encourage students to compare their total cost to their budget aloud so peers can hear the comparison.
What to look forPresent students with pictures of 2-3 items with prices clearly marked (e.g., a pencil for 5 rupees, an eraser for 3 rupees). Ask them to write down the total cost and then, if they pay with a 10 rupee note, calculate the change they should receive.

Generate Complete Lesson→A few notes on teaching this unit
Start with concrete coins and notes before moving to pictures or digital representations. Avoid rushing to worksheets; manipulatives build number sense that paper cannot. Research shows that peer teaching during role-plays strengthens understanding faster than teacher-led explanations alone. Model clear steps for addition and subtraction with money and provide sentence stems to support language development.
By the end of these activities, students will confidently add prices of two or three items to reach totals up to 50 rupees. They will pay exact amounts or more and calculate change correctly in role-plays and games. Discussions will show they understand why we use money instead of bartering toys for snacks.
Watch Out for These Misconceptions
During Coin Match, watch for students who count coins by quantity rather than value. Place 10 one-rupee coins and two five-rupee coins on the table and ask them to group coins that make the same total.
Ask them to place ten 1-rupee coins in one row and two 5-rupee coins in another, then count aloud to see both rows total 10 rupees. Repeat with different sets until they recognise that quantity alone does not determine value.
During Market Stall Exchange, listen for comments like 'the shopkeeper gave extra money for free'. Pause the role-play and ask the buyer to explain why the shopkeeper returned money using the words 'change' and 'cost'.
Ask the shopkeeper to show the cost on a price tag and subtract it from the money received while explaining each step aloud. Repeat the scenario with a peer demonstration.
During Shopping Budget, notice students who insist they must pay exact amounts. Ask them to consider a scenario where they only have a 20-rupee note to buy a 15-rupee item and discuss what happens next.
Guide them to calculate the difference and introduce the word 'change' in context. Use real coins to show the overpayment and subtraction process step-by-step.
