A 60 minute lesson in which students will calculate sale price using percentage discounts of 10%, 25% and 50%.
In order to revise the content of the previous lesson, ask the students:
What is a discount?
How is a discount rate usually expressed?
What methods can be used to calculate the discount amount on a particular item?
Discuss the method to be used when calculating the sale price of an item, as outlined on slide 16 of the Calculating Discounts PowerPoint. Ensure that the students understand the difference between the discount amount and the sale price of an item.
Use the annotated examples on slides 17-18 to demonstrate how to calculate the sale price of an item. As a class, complete the example question on slide 19.
Display the review questions on slide 20. Monitor and support the students as they individually complete the questions on the slide.
Display and discuss the answers to the review questions on slide 21. As the students correct their answers, encourage them to raise any queries or concerns.
Provide the students with a copy of the Purchase Percentages (B) Worksheet from the Money and Financial Mathematics Worksheets – Year 6 (do not use the Purchase Percentages (A) Worksheet as these questions appear in the unit assessment task). Answer any questions, then monitor and support the students as they complete the worksheet.
Correct the worksheet as a class. As the students correct their answers, encourage them to raise any queries or concerns.
Encourage fast finishers to write their own calculating sale price questions to swap with a partner.
Allow less confident students to complete the review questions in a small group with the support of a teacher or teacher aide.
