Buyer Beware: Rates, Ratios, Percents, and Proportions

Students first study rates through unit pricing and use graphs and calculators to find the best buy. Students then learn about different ways to think about and solve problems with ratios and proportions. Finally, students explore percents and pie charts by organizing information for sports teams and planning a sports banquet. Throughout the unit, students are in the role of consumer reporters, reporting on fictitious claims made about different products.
