This slide aims to show the practical application of unit prices in everyday life. Start by explaining that a unit price is the cost per unit of measure (like per ounce, liter, or pound) which allows consumers to compare prices of different-sized packages of the same product. Encourage students to think about how this could be useful when shopping on a budget or trying to get the most value for their money. Walk through a few examples with the class, comparing the unit prices of different brands of a common product, such as cereal or soda. This will help them understand how to make cost-effective decisions and become more financially literate consumers. The activity will involve students calculating unit prices of items they commonly see or use, fostering engagement and practical understanding.
Class Activity: Unit Price Analysis
– Find unit prices using store flyers
– Determine best value items
– Compare prices of similar items to see which is more cost-effective
– Present findings to the class
– Reflect on the activity
– Think about what you learned from this exercise
|
This activity is designed to give students practical experience with unit prices, an essential concept in consumer math. By analyzing real store flyers, students will learn how to calculate the unit price of items and determine which products offer the best value for money. Divide the class into small groups and provide a variety of flyers from local stores. Encourage students to look for different sizes and brands of the same product to compare. After calculations, each group will present their findings, discussing why certain items are a better purchase. This will help them understand the importance of unit prices in everyday shopping and budgeting. Possible variations of the activity could include comparing generic vs. brand-name products, bulk purchases vs. single items, or finding the best deals in a given budget.
