Market Maths: Costs, Combinations, and Change
Lesson
A common error is treating the price list as per-item rather than per-kilogram; draw attention to the unit of sale before children begin computing costs. When checking combinations for ₹163, encourage children to record their working systematically so they can confirm no combination is counted twice. The currency-option task sharpens understanding of how notes and coins compose a total.
0–8Introduce the Mawlynnong market scene using the price list on p.97. Children read the prices aloud and handle play-money notes to build familiarity with the denominations. Pose: 'If you buy 2 kg of oranges and 1 kg of tomatoes, what do you pay?' Let pairs compute and share.
8–25Let Us Do, p.97 ("find costs and combinations that sum to ₹163...."). Children work in pairs, listing different fruit-vegetable combinations from the price list that together cost exactly ₹163. Emphasise that more than one answer is valid; pairs compare combinations with a neighbouring pair.
25–37Let Us Do, p.98 ("which currency options can be used to pay ₹165...."). Children examine the five currency-combination options for buying 3 kg of bananas. They check each option by totalling the coins/notes shown and deciding if the total meets or exceeds ₹165. Groups share reasoning.
37–40Quick class discussion: 'Which combinations worked and why? What made some options impossible?' Assign the Cost–Paid–Balance grid task on p.98 as home practice.
Homework
Complete 9 Cost–Paid–Balance grids by finding the missing value in each row. (**Let Us Do, p.98**)
Let Us Do, p.97 — Find costs for different quantities of fruits/vegetables; find what combinations sum to ₹163 (more than one possibility).
Apples cost ₹40 per kg and mangoes cost ₹60 per kg. Priya's mother wants to spend exactly ₹200. Which combination could she buy?
- A 1 kg apples and 3 kg mangoes
- B 2 kg apples and 2 kg mangoes
- C 3 kg apples and 1 kg mangoes
- D 4 kg apples and 1 kg mangoes
B. 2 kg apples and 2 kg mangoes
What each wrong option reveals
- A Child computed 1×40+3×60 = 40+180 = ₹220, exceeding the target — did not verify equality.
- C Child computed 3×40+1×60 = 120+60 = ₹180, not ₹200 — did not check the target sum.
- D Child computed 4×40+1×60 = 160+60 = ₹220, exceeding the target — confused 'at most' with 'exactly'.
