Now doubt, the idea of shopping for shoes will certainly engage a middle school student. This comprehensive performance task will help your class apply their knowledge of decimals and percent to find the best price for Kuan's new shoes. The students will examine sales information from three different stores, which are located in three different sales tax districts. To extend the activity, there are guided questions to help students compare the offers in depth. Finally students will create their own store advertisement, price, and discount to help Kuan find an even better deal.

Log in to see state-specific standards (only available in the US).
Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent.
Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. For example: If a woman making $25 an hour gets a 10% raise, she will make an additional 1/10 of her salary an hour, or $2.50, for a new salary of $27.50. If you want to place a towel bar 9 3/4 inches long in the center of a door that is 27 1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation.
Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related. For example, 𝘢 + 0.05𝘢 = 1.05𝘢 means that “increase by 5%” is the same as “multiply by 1.05.”
