One of a series of teaching units designed to introduce secondary school students to the Canadian economy, this handbook contains instructional materials on Canada's role in the world economy. Ten sections contain readings and suggestions for activities related to Canadian trade, tariffs, the Canada-United States automobile pact, Canada-United States free trade, trade policies in the 1980's, balance of payments, the foreign exchange market, capital flows, the Canadian exchange rate, and the international monetary system. Readings are illustrated with charts, graphs, and cartoons. A final section, a teacher's guide, clarifies learning objectives, terms, and suggested activities for each of the student sections. (LP)
