**CONTENT OF THE LESSON **** **

**LESSON ONE – INTRODUCTION **

Pupil’s Activities 1 – Multiplication of Two Whole Numbers Together

Oral Questions

1. 2 x 3 = 6

2. 4 x 3 = 12

3. 5 x 6 = 30

4. 3 x 9 = 27

Pupil’s Activities 2 – Multiply The Result in Activities 1 by Another Whole Numbers1. 2 x 3 = 6 x 3 = 18

2. 4 x 3 = 12 x 2 = 24

3. 5 x 6 = 30 x 2 = 60

4. 3 x 9 = 27 x 1 = 27

Teacher’s/Pupil’s Activities 3 – Multiplication 3 Whole Numbers, Taking 2 At A Time

Working Examples

1. 2 x 3 x. 2

= (2 x 3) x 2

= (6) x 2

= 6 x 2

= 12

Or

2 x 3 x. 2

= 2 x (3 x 2)

= 2 x (6)

= 2 x 6

= 12

2. 3 x 2 x 5

= 3 x (2 x 5)

= 3 x (10)

= 3 x 10

= 30

Or

3 x 2 x 5

= (3 x 2) x 5

= (6) x 5

= 6 x 5

= 30

Pupil’s Activities 2 – Exercise/Take Home1. 3 x 6 x 2

2. 8 x 3 x 4

3. 2 x 6 x 5

4. 5 x 4 x 2

**LESSON TWO – AS IN LESSON ONE **

**LESSON THREE – QUANTITATIVE REASONING **

As stated in Quantitative Books or Textbooks

**PRESENTATION**

To deliver the lesson, the teacher adopts the following steps:

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;

2. Guides pupils to multiply three 1-digit numbers taking two at a time e.g. 3 x 4 x 5 =(3 x 4) x 5 or 3 x (4 x 5).

Pupil’s Activities – Carry out series of multiplication of three 1-digit numbers taking two at a time.

**CONCLUSION**

To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.

**LESSON EVALUATION **

**Pupils to multiply given three 1-digit numbers taking two at a time.**
