Title: The Application of Mathematics in Daily Life - Lesson Plan for Buying Mineral WaterObjectives

Title: The Application of Mathematics in Daily Life -Lesson Plan for Buying Mineral Water Objectives: ● To understand the importance of mathematics in daily life ● To learn how to use simple mathematical equations in buying mineral water ● To improve mathematical skills Materials: ● Calculator ● Mineral water price list Introduction (10 minutes): Begin the lesson by asking students if they know how mathematics is applied in daily life. Give examples such as calculating change, measuring ingredients for cooking, and budgeting money. Tell the class that today's lesson will focus on buying mineral water. Body (40 minutes): 1. Show the class amineral water price list. Ask them to study the list and calculate the price of one bottle of mineral water. Demonstrate how to use the formula: Price of 1bottle =Price per pack ÷ Number of bottles per pack. Do some practice problems with the class, using different pack sizes. 2. Discuss with the class the concept of discounts. Show them aprice list that offers discounts for bulk purchases. Demonstrate how to use the formula: Total price after discount =Original price × (100% -Discount percentage) ÷ 100%. Do some practice problems with the class, using different discount percentages. 3. Ask the students to use their mathematical skills to compare the prices of different brands of mineral water. Give them afew price lists from different stores and ask them to find the cheapest brand. 4. Encourage the students to use estimation to make quick calculations. For example, if the price of one pack of mineral water is $5 and there are 6bottles in
