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 Numbers
1. 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 Home
1. 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.
