PRESENTATION

TEACHER’S ACTIVITY

PUPIL’S ACTIVITY

STEP 1 – INTRODUCTION

Introduces real-life problems involving multiplication and division of money, including scenarios like online shopping.

Pupils listen and participate in a brief discussion.

STEP 2 – EXPLANATION

Demonstrates real-life problems involving the multiplication and division of money:

  

Example 1: You buy 3 pens at 5 Naira each. How much do you pay?

    

Example 2: You divide 20 Naira into 4 equal parts. How much is each part?

Pupils work on similar real-life problems in pairs.

STEP 4 – NOTE TAKING

Pupils take notes on how to apply money multiplication and division to real-life problems.

Pupils write down examples in their notebooks.

NOTE:

  • When multiplying money in real life, think about the number of items being purchased and the cost per item.
  • Example: If one T-shirt costs 500 Naira, how much do 3 T-shirts cost? Answer: 500 Naira × 3 = 1500 Naira.
