Standard: Use Math to Solve Problems and Communicate

Component of Performance How activity addresses component Understand, interpret, and work with pictures, numbers, and symbolic information. Students work with decimals, fractions and percents to solve percent problems. Apply knowledge of mathematical concepts and procedures to figure out how to answer a question, solve a problem, make a prediction, or carry out a task that has a mathematical dimension Students decide what numbers can be used to make a reasonable estimate to a percent problem and use problem solving to identify the parts of a percent problem. Define and select data to be used in solving the problem Students determine the parts of a percent problem. Determine the degree of precision required by the situation Students decide if making an estimate is appropriate for the situation and round to appropriate place. Solve problem using appropriate quantitative procedures and verify the results are reasonable Students will determine if their answer (price) is reasonable. Communicate results using a variety of mathematical representations, including graphs, charts, tables, and algebraic models Students will verbally explain their procedure to find the estimate.

Purposeful, Transparent, Building Expertise

Purposeful and Transparent Adults want to be economical shoppers. To save money, students want to determine how much they will save and the actual item cost by using percentage off sales. Contextual Students will be using newspaper ads to practice their percentage off skills in order to become more economical shoppers. Building Expertise Students are familiar with calculating percentages, but now are using this knowledge for a real-life experience and not just classroom practice.
