Teach How to Calculate Discounts and Sale Prices

Dad is buying a grill. It is priced at $400, but is on sale for 25% off. 

What is the discount, and how much will Dad end up paying for the grill?

To work out the answer to this question, your students will need to know how to calculate discounts and sale prices. 

• A discount is a price reduction that is being applied to the regular price of an item. Discount rates are usually expressed as a percentage.
• The sale price is the amount paid by the consumer once the discount is applied. The discount is subtracted from the original price.

This comprehensive 19-slide teaching presentation teaches your students how to calculate discounts and sale prices by finding equivalent fractions and decimals for the percentage discount. It explores each strategy in detail using annotated examples of each process. It also includes shared questions and review activities that the class can work through together as a means of checking for understanding.

The key content addressed in this teaching presentation includes:

• Discounts in everyday life
• What is a discount?
