After this lesson, students will be able to:

Calculate the discount amount and sale price of an item given the original price and the percent discount.

Solve problems involving finding the original price of an item given the sale price and the percent discount.

Determine the total cost including tips based on a percentage of the bill amount.

Apply the concepts of discount, sale price, and tips to real-life situations, such as shopping and dining out.

Before this lesson, students should be familiar with:

How to convert between decimals and percents

Basic understanding of multiplication and division of integers and decimals

Pencils

Colored pencils or markers

Discount

Sale price

Tips

Percentage

As a hook, ask students why it is important to calculate discounts, sale prices, and tips in real life situations. Refer to the last page of the guided notes as well as the FAQs below for ideas.

Use the first page of the guided notes to introduce the concept of discounts. Walk through how to calculate the discount amount and the sale price. Explain the difference between the discount and the sale price. Have students fill in the steps to calculating discount and sale price. Then, have students practice using the 3 problems in the "you try" section on the page. Students will have to calculate the sale prices of the different furniture shown.

Next, use the second page of the guided notes to introduce tip calculations. Discuss the purpose of tipping and how it is typically calculated as a percentage of the total bill. Show students how to calculate the tip amount and the total amount, including the tip. Emphasize the importance of good tipping etiquette and have students fill in some services like waitressing, salons, and food delivery that often accept tips.

Based on student responses, reteach concepts that students need extra help with. If your class has a wide range of proficiency levels, you can pull out students for reteaching, and have more advanced students begin work on the practice exercises.

After finishing the first two pages of the guided notes, have students practice finding discounts, sale prices, and tips using the maze activity (page 3). Walk around the classroom to answer any questions students may have.

Fast finishers can dive into the color by number activity (page 4) for extra practice. You can assign it as homework for the remainder of the class.

Bring the class back together, and introduce the concept of calculating tips and sale price in real-life situations. Explain that understanding how to find the tip when dining at a restaurant or calculating the sale price when shopping can be useful in everyday life. Use the last page of the guided notes where students will read about a detailed example of real life applications.

Provide examples and scenarios where calculating tips and sale prices are relevant. For example, you can discuss scenarios such as:

Dining at a restaurant: Explain that when dining out, it is customary to leave a tip for the server. Show the students how to calculate a specific percentage tip based on the total bill. Discuss common tipping percentages, such as 15%, 18%, and 20%, and emphasize the importance of considering the quality of service when determining the appropriate tip.

Shopping during a sale: Explain that when there is a sale at a store, the price of an item is often reduced by a certain percentage. Show the students how to calculate the sale price of an item by applying the discount percentage to the original price. Discuss the concept of finding the better deal between items with different sale prices and comparing the savings.

Discounts and coupons: Explain that discounts and coupons are often used to reduce the price of items. Show the students how to calculate the discounted price using a specific percentage discount or a fixed amount coupon. Discuss the importance of reading the fine print to understand the terms and conditions of the discounts or coupons.

Encourage students to share their own experiences or examples of situations where they have encountered the need to calculate tips or sale prices. This will help them see the relevance and practicality of the concept in their daily lives.

Refer to the FAQ section or provide additional examples and scenarios to reinforce the concept further, if needed.

A fun, no-prep way to practice discount, sale price, and tips is Doodle Math — they’re a fresh take on color by number or color by code. It includes multiple levels of practice, perfect for a review day or sub plan.

Here is an activity to try:

A discount is a reduction in price or cost. It is usually expressed as a percentage off the original price.

To calculate the sale price, you need to subtract the discount amount from the original price. Here are the steps:

**Step 1:**Convert the discount percentage to a decimal by dividing it by 100.**Step 2:**Multiply the decimal by the original price to find the discount amount.**Step 3:**Subtract the discount amount from the original price to get the sale price.

To calculate the amount of discount, you need to multiply the original price by the discount percentage. Here are the steps:

**Step 1:**Convert the discount percentage to a decimal by dividing it by 100.**Step 2:**Multiply the decimal by the original price to find the discount amount.

To find the tip for a bill, you need to multiply the bill amount by the tip percentage. Here are the steps:

**Step 1:**Convert the tip percentage to a decimal by dividing it by 100.**Step 2:**Multiply the decimal by the bill amount to find the tip.

Sure! Here's an example:

Original price: $100

Discount percentage: 20%

To find the sale price:

**Step 1:**Convert the discount percentage to a decimal: 20% = 0.2**Step 2:**Multiply the decimal by the original price: 0.2 * $100 = $20**Step 3:**Subtract the discount amount from the original price: $100 - $20 = $80

So, the discount amount is $20 and the sale price is $80.

To find the total amount after adding a tip, you need to add the tip amount to the original bill. Here are the steps:

**Step 1:**Find the tip amount by multiplying the bill amount by the tip percentage (converted to a decimal).**Step 2:**Add the tip amount to the bill amount to get the total amount.

Certainly! Here are some real-life examples of sale price:

A store offers a 30% discount on a $50 shirt. The sale price would be $35.

A restaurant reduces the price of a meal by 15% during a special promotion. If the original price of the meal was $100, the sale price would be $85.

An online retailer offers a 20% discount on a $200 electronic gadget. The sale price would be $160.

Percentages and discounts are commonly used in everyday situations. Here are some examples:

Calculating how much you will save during a sale or promotion.

Determining the amount of money to tip at a restaurant or for a service.

Understanding the discount applied to a coupon or promotional code when shopping online.

Comparing prices of products with different discounts to find the best deal.
