B. Developmental Activities
1. Activity
a)
Presentation
·
Present
the following problem:
Joel went to a sale at SM. He saw
a Tshirt 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.
