1. Odd and Even Numbers Even Numbers end in 2 4 6 8 Odd Numbers end in 12 4 6 8
Odd Numbers end in 1 3 5 7 9

2. Objectives
By the end of this section/lesson, students should be able to:
Identify Odd and Even Numbers

3. Activity 1: Even/Odd
A few students are allowed to sit in pairs while the remaining students sit ‘one at a table’.
Teacher to brainstorm with students on the difference between ‘pair’ and ‘loner’.
Teacher introduces even and odd numbers (0-10) by referring to pairing.
All numbers which contain only pairs are called even numbers.
A figure having pairs with one left out is called an odd number.

4. Activity 1: Even/Odd

5. Activity 2: Even/Odd
On the hundred chart, circle all numbers that can be paired in blue.
Note: Students are either made to work in pair or on their own on the hundred chart given.

6. Even/Odd Hence, 2, 4, 6, 8, 10 are even numbers and
1, 3, 5, 7, 9 are odd numbers
We should not forget the number zero!
0 is an even number.

7. Even/Odd for greater numbers
How do we know which number is even or odd when the figure gets greater?
Since 0, 2, 4, 6 and 8 are even numbers, all figures having these numbers at the end are even numbers
For example, 1234 has a ‘4’ at the end. Therefore, it is an even number.

8. Even/Odd for greater numbers
Since 1, 3, 5, 7, 9 are odd numbers, all figures having these numbers at the end are odd numbers.
Example:
4061: odd number as it ends with ‘1’.

9. Consolidation work
Determine whether the following are odd or even numbers.
i A. Even B. Odd
ii A. Even B. Odd
iii A. Even B. Odd
iv A. Even B. Odd
v A. Even B. Odd
vi A. Even B. Odd
