10 lessons in this unit
Why people trade
Define trade, surplus, specialisation and interdependence, explain why people and countries trade (different resources and skills, surplus and shortage, wanting variety, lower cost), explain how specialisation and trade benefit both sides, and give examples from household, local, national and international levels.
Lesson 2Local trade
Define retail, wholesale, vendor and weekly market, describe local trade in Sierra Leone (daily markets, weekly markets known as lumas or loumas in rural areas, street vendors, shops, traders who buy from farmers and sell in towns), explain the role of the middle trader and market associations, explain challenges (transport, storage, prices, safety), and explain fair weights and measures.
Lesson 3Regional trade
Define regional trade, ECOWAS, border crossing and customs, describe trade among West African countries including cross-border trade of food, fish, palm oil and manufactured goods, explain the role of the Economic Community of West Africa States (ECOWAS, founded in 1975) and the Mano River Union (1973) in easing trade, explain challenges at borders (delays, fees, paperwork), and explain benefits of regional cooperation.
Lesson 4Imports
Define import, customs duty, dependence and local substitute, explain why countries import goods they cannot produce or cannot produce enough of (such as fuel, machinery, vehicles, medicines, and, in Sierra Leone, a share of rice and cooking oil), describe how imports arrive through ports and airports, explain benefits and risks of depending on imports, and explain how local production can replace some imports.
Lesson 5Exports
Define export, raw material, value added and foreign exchange, describe Sierra Leone’s main exports (iron ore, rutile, bauxite, diamonds, cocoa, coffee, fish, timber), explain how exports earn foreign exchange, explain how processing raw materials adds value and creates jobs, and explain risks of relying on a few exports (world price changes) and how diversifying helps.
Lesson 6Transportation networks
Define transport network, freight, cargo and logistics, explain how roads, rail, ports and airports move goods for trade (linking with the geography of networks studied earlier), compare costs, speed and capacity of road, sea, rail and air freight, explain how transport costs affect prices, and explain why cooperation and maintenance matter.
Lesson 7Communication technologies
Define communication technology, mobile money, e-commerce and digital divide, explain how phones, radio and the internet support trade (prices, orders, payments, advice), describe benefits such as faster information and wider markets, explain challenges (network coverage, cost, scams, privacy), and explain safe and responsible use.
Lesson 8International economic connections
Define globalisation, multinational company, trade agreement and global supply chain, explain how economies connect through trade, investment, labour, aid and remittances, describe supply chains for everyday goods crossing many countries, explain the role of organisations such as the World Trade Organization (1995) and the African Union’s continental free trade area, and explain benefits and concerns of global links.
Lesson 9Benefits and challenges of trade
Define benefit, challenge, fair trade and protectionism, weigh benefits of trade (choice, lower prices, jobs, new ideas) against challenges (competition for local producers, dependence, environmental cost, unfair pay), explain how fair trade practices and rules protect producers, and practise balanced reasoning with evidence.
Lesson 10Trade simulation
Take part in a classroom trade simulation using pretend tokens and goods cards, apply ideas of surplus, specialisation, prices, transport and fair trade, record results in a table, compare outcomes, reflect on fairness and cooperation, and connect the activity to real trade without competing over real goods.
