CONTENT OF THE LESSON

LESSON ONE – INTRODUCTION TO EVEN AND ODD NUMBERS

Teacher’s/Pupil’s Activities 1 – Introductory Questions

Question 1

Divide the following numbers – 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 by 2.

1 ÷ 2 = 0 Remainder 1

1

2 ÷ 2 = 1 Remainder 0

11

3 ÷ 2 = 1 Remainder 1

11 1

4 ÷ 2 = 2 Remainder 0

11  11

5 ÷ 2 = 2 Remainder 1

11  11  1

6 ÷ 2 = 3 Remainder 0

11  11  11

7 ÷ 2 = 3 Remainder 1

11  11  11  1

8 ÷ 2 = 4 Remainder 0

11  11  11  11

9 ÷ 2 = 4 Remainder 1

11  11  11  11 1

10 ÷ 2 = 5 Remainder 0

11  11  11  11 11

Question 1 – Separate the number with remainder 0 and 1

Numbers with remainder 0

2, 4, 6, 8 and 10.

Numbers with remainder 1

1, 3, 5, 7 and 9.

Guides pupils to present the numbers with 0 and 1 in a table with heading even and odd numbers.

Teacher’s remark – 0, 2, 4, 6, 8 and 10 are divisible by 2 without remainder. They are called even numbers. 1, 3, 5, 7 and 9 have remainder 1 when divided by 2. They are called odd numbers.

Pupil’s Activities 2 – Group Numbers into Even and Odd Numbers 11 to 20

Group the following numbers – 11, 12, 13, 14, 15, 16, 17, 18, 19 and 20 into even and odd numbers.

11 ÷ 2 = 5 Remainder 1

11  11  111111  1

11 is odd number.

12 ÷ 2 = 6 Remainder 0

11  11  11  11  11  11

12 is even number.

13 ÷ 2 = 6 Remainder 1

11  11  11  11   11  11  1

13 is odd number.

Teacher’s remark – Note that, 0, 2, 4, 6, 8 and 10 are even number. While 1, 3, 5, 7 and 9 are odd numbers. All numbers that end with 0, 2, 4, 6 and 8 are known as even numbers. Also, all numbers that end with 1, 3, 5, 7 and 9 are known as odd. This is the easiest way to identify even and odd numbers.

For example, 11 ends with 1, 13 ends with 3, 15 ends with 5, 17 ends with 7 and 19 ends with 9. Therefore, 11, 13, 15, 17 and 19 are odd numbers while 12, 14, 16, 18 and 20 are even numbers.

Pupil’s Activities 3 – Class Exercises/Take Home

Find all the even and odd between 21 to 50.

LESSON TWO – EVEN AND ODD NUMBERS BETWEEN 51 TO 100

As in pupil’s activities 2 in lesson one.

LESSON THREE – SUM OF EVEN AND ODD NUMBERS

Teacher’s/Pupil’s Activities 1 – Sum of Two or More Even Numbers

Teacher’s comment – Adding two or more even numbers together gives us even numbers. For example,

6 + 4 = 10

2 + 4 + 8 = 14

10 and 14 are even numbers.

Teacher’s/Activities 2 – Sum of Two or More Numbers

Teacher’s comments – The sum of two odd numbers gives us even numbers. The sum of three odd numbers gives us even numbers, etc. For example,

1 + 3 = 4, even number.

3 + 5 + 7 = 15, odd number.

Pupil’s Activities 3 – Class Exercises/Take Home

Indicates whether the results of the sum is even or odd numbers,

1. 2 + 4 + 6 =

2. 12 + 5 =

3. 12 + 5 + 1 =

4. 5 + 7 + 7 =

5. 9 + 21 =

LESSON THREE – CONTINUATION OF EVEN AND ODD NUMBERS

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 identify even and odd numbers.

Pupil’s Activities – Identify and differentiate between even and odd numbers.

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:

1. differentiate between even and odd numbers.

2. identify even and odd numbers.
