Experiential Learning
1. Divide the class into groups of 4 and classify them as sellers and buyers.
3. Distribute some play-currency notes and coins to each group.
4. Ask the seller groups to collect some items, like pencils, books, notebooks, water bottles,
chalks, etc. and to put a price tag on each item.
5. The buyer groups can randomly choose some seller groups and buy items from them.
They can use the dummy money for the transactions. The seller group will return the
change, if required.
6. Each buyer group must buy atleast 4 items and each seller group must sell atleast 2 items.
7. Encourage the buyers to negotiate for better prices.
8. Teach them decision making by comparing the prices of the same article (e.g. pencil)
among the different sellers.
9. Ask questions like:
l From which seller will you buy the pencil – the one who sells it for `5 or the one who

sells it for `9?
l What will happen if the price of your items is much higher than the other sellers?
