CONTENT OF THE LESSON
LESSON ONE – DIVISION OF TWO OR THREE DIGITS NUMBERS BY NUMBERS NOT MORE THAN 9
Pupil’s Activities 1 (Introductory Activities) – Share ₦1,000 between two, three and four people.
Solutions
- 2 pupils shared ₦500 each.
- 3 pupils shared ₦330 balance ₦10
- 4 pupils shared ₦250 each.
Teacher’s remark – Division means grouping, splitting or dividing items among groups. Today’s lesson, we are going to be learning division of Whole Numbers.
Pupil’s Activities 2 – Division of 2 Digit Numbers without Remainder
Divide 2 digits by numbers not more than 9 using counting objects.
- 12 ÷ 4 = 3
////////////
- 25 ÷ 5 = 5
////////// ///// ///// /////
Pupil’s Activities 3 – Division of 2 Digit Numbers without Remainder
Divide 2 or 3 digits by numbers not more than 9 using counting objects.
Solution
12 ÷ 5 = 2 Reminder 2
///// ///////2. 25 ÷ 7 = 3 Reminder 4
/////// /////// ///////////
Teacher’s activities – Supervise the pupil’s activities.
Pupil’s Exercises/Assignments
Divide the following numbers by 7,
1. 14
2. 20
3. 28
4. 49
QUANTITATIVE REASONINGS
Complete the following –
1. 48 ÷ ____ = 6
2. 55 ÷ 10 = ____ R 5
3. 65 ÷ 9 = 6 R ____
4. 49 ÷ ____ = 7
LESSON TWO – DIVISION OF TWO OR THREE DIGIT NUMBERS BY MULTIPLE OF 10 UP TO 50
Pupil’s Activities 1 (Introductory Activities) – Find the products of the following two nurseries –
1. 10 x 2 = 20
2. 10 x 3 = 30
3. 10 x 4 = 40
4. 10 x 5 = 50
Teacher’s/Pupil’s Activities 2 – What are numbers of 10 in 20, 30, 40 and 50?
10 in 20 is 2 times, i.e. 10 x 2 = 20
10 in 30 is 3 times, i.e. 10 x 3 = 30
10 in 40 is 3 times, i.e. 10 x 4 = 40
10 in 50 is 3 times, i.e. 10 x 5 = 50
Teacher’s remark – 50/10 = 5, 40 ÷ 10 = 4, 30 ÷ 10 = 3, and 20/10 = 2. In today’s lesson, we are going to be dividing by the multiple of 10 up to 50.
Teacher’s/Pupil’s Activities 2 – Division of 3 digits by numbers by multiple of 10 up to 50
Guides the pupils to use stroke counting and additive charts.
For example,
70/10. If a stroke is 10, how many stroke will make the sum of 70?
/ = 10,
// = 20,
/// = 30,
//// = 40,
///// = 50,
////// = 60,
/////// = 70.
Then, ask them to count the number of strokes that sum up to 70.
Therefore, 70/10 = 7.
Pupil’s Exercise/Assignments – Follow the teacher’s guide and attempt the following questions.
1. 100/10 = 10
If / = 10,
/ + / + / + / + / + / + / + / + / + / = 100
2. 127 ÷ 20 = 6 R 7
If / = 20,
/ + / + / + / + / + / = 120 R 7
3. 150/ 30 = 5
If / = 30,
/ + / + / + / + / = 150
4. 260/50 = 5 R 10
If / = 50
/ + / + / + / + / = 250 + 10
LESSON THREE – OTHER APPROACHES ON DIVISION OF TWO OR THREE DIGITS NUMBERS NOT MORE THAN 9 AND MULTIPLE OF 10 UP TO 50
Guide pupils to use other approach to division of numbers.
For example,
Pupil’s Exercise/Assignments
1. 65 ÷ 9 =
2. 260/50 =
