2. Motivation

·         Discuss that the man in mystery picture is Henry Sy, the owner of SM Malls and the richest man in the Philippines. Share his successful life story to the students.

Valuing: What do you think made Henry Sy successful? Was he wise in managing his money? In what way can we manage and save our money?

·         Ask:  Do you go to malls like SM or Robinson? Have you gone to a mall-wide sale? Why do people like going to a sale?

B. Developmental Activities
1. Activity

a) Presentation
·         Present the following problem:

Joel went to a sale at SM. He saw a T-shirt that costs P350 with 20% discount.
How much is the discount? The sale price?

·         Define the terms discount, original/old price, discount rate and the sale/new price to the students
·         Let students identify the terms in the given problem.

2) Analysis

·         Analyze the problem using block model approach.

 80% (New/Sale Price) 20% (Discount)

100%
(Old/Original Price)

3) Abstraction and Comparison

·         Have students derive the formula of solving the discount using Techan’s triangle.

P = B x R
Discount = Original Price x Discount Rate

·         Let students solve the problem using the derived formula.
Discount = Original Price x Discount Rate
= P350 x 20%
= P70
Sale Price = Original Price – Discount
= P350 – P70
= P280

Therefore, Joel got P70 discount and paid P280.

4) Application
a) Exercises (Pair-Share Activity)
·         Solve for the discount and the sale price of the following items:

 Item Original Price Discount Rate 1. Blouse P400 50% 2. Pants P950 20% 3. Socks P90 15% 4.  Cap P150 30% 5. Jacket P1200 10%

5) Generalization

·         Ask: What is the formula in solving discount? New/sale price?

C. Reinforcement Activities
a) Independent Practice
·         Solve the following word problems independently:
1. Lotlot wants to buy a doll worth P800 with 50% off. What is the new price of the doll?
2. A set of utensils is on sale with 12% discount. How much is the discount if the original price is P500?
3. Kiko buys a pair of shoe which is on sale with 10% discount. How much will he pay in the cashier if the shoe originally costs P1500?

IV. Evaluation

·         Solve the following problems:
1. Mr. Yu bought a rice cooker which costs P600. How did he pay if the rice cooker had 30% discount?
2. A dress costs P750 with 20% discount. How much is the new price?
3. Boyet wants to buy a toy truck worth P800 with 40% off. What is the new price of the toy truck?
