The lesson focuses on applying ratios and proportions to solve applications. Students begin by dividing a whole (such as a candy bar, amount of money, or group of people) into parts with given ratios. They then extend ratios to 3 and 4 terms, and use ratios to find percents. Next, students write and use proportions to solving real-world problems, including currency exchange.
