PERIOD 1 and 2:

PRESENTATION

Step

Teacher’s Activity

Pupil’s Activity

STEP 1 – INTRODUCTION

Introduces the concept of profit and loss percentage.

Pupils listen and ask questions.

STEP 2 – EXPLANATION

Explains how to calculate profit and loss percentage using the formula: Profit/Loss Percentage = (Profit/Loss ÷ Cost Price) × 100.

Pupils listen and take notes.

STEP 3 - DEMONSTRATION

Demonstrates calculating profit and loss percentage with an example.

Pupils observe and work on an example.

STEP 4 - NOTE TAKING

Teacher writes examples and formulas on the board.

Pupils take notes on profit and loss calculations.

NOTE (On the Board):
Profit and Loss Percentage:

  • Formula: Profit Percentage = (Profit ÷ Cost Price) × 100
  • Example: Cost price = N100, selling price = N120. Profit = N120 - N100 = N20. Profit percentage = (20 ÷ 100) × 100 = 20%.

EVALUATION:
• Ask pupils to calculate the profit percentage for given prices.

CLASSWORK:
• Solve 5 problems on calculating profit and loss percentage.

ASSIGNMENT:
• Calculate profit or loss percentage for 5 different sales.

CONCLUSION:
Teacher commends pupils and encourages practicing at home.

 

PERIOD 3 and 4:

PRESENTATION

Step

Teacher’s Activity

Pupil’s Activity

STEP 1 – INTRODUCTION

Introduces the concept of discount and commission.

Pupils listen and participate.

STEP 2 – EXPLANATION

Explains how to calculate discount and commission with examples.

Pupils listen and take notes.

STEP 3 - DEMONSTRATION

Demonstrates calculating discount and commission using sample bills.

Pupils practice calculating discount and commission.

STEP 4 - NOTE TAKING

Teacher writes examples and formulas on the board.

Pupils take notes on discount and commission calculations.

NOTE (On the Board):
Discount and Commission:

  • Formula for discount: Discount = (Discount Percentage × Price) ÷ 100
  • Formula for commission: Commission = (Commission Percentage × Sale Price) ÷ 100
    Example:
    • Discount on a N500 item at 10% = (10 × 500) ÷ 100 = N50
    • Commission on N1,000 sale at 5% = (5 × 1000) ÷ 100 = N50

EVALUATION:
• Ask pupils to calculate discount and commission for given prices.

CLASSWORK:
• Solve 5 problems on calculating discount and commission.

ASSIGNMENT:
• Complete 5 real-life problems on discount and commission calculations.

CONCLUSION:
Teacher encourages students to keep practicing.

 

PERIOD 5:
