E: CONTENT
Even Numbers
An even number can be divided into pairs without any object left over.
Examples:
2, 4, 6, 8, 10, 12
Example with objects:
🍎🍎 🍎🍎 🍎🍎
There are 6 apples.
They can be put into pairs with none left over.
So 6 is an even number.
Even numbers usually end in:
0, 2, 4, 6 or 8
Odd Numbers
An odd number leaves one object without a partner when grouped in pairs.
Examples:
1, 3, 5, 7, 9, 11
Example:
🍊🍊 🍊🍊 🍊
There are 5 oranges.
One orange is left without a partner.
So 5 is an odd number.
Odd numbers usually end in:
1, 3, 5, 7 or 9
Examples
- 12 – even
- 17 – odd
- 24 – even
- 35 – odd
- 40 – even
- 51 – odd
F: LESSON PRESENTATION
F1: Teachers’ Activities
- Introduces odd and even numbers.
- Groups counters into pairs.
- Shows examples of numbers with and without remainders.
- Writes odd and even numbers on the board.
- Guides pupils to sort numbers.
- Gives simple exercises.
F2: Pupils’ Activities
- Group objects into pairs.
- Identify numbers with no object left over.
- Identify numbers with one object left over.
- Sort numbers into odd and even groups.
- Answer exercises.
G: CONCLUSION
The teacher revises that even numbers can be grouped into pairs with nothing left, while odd numbers leave one object without a partner.
The pupils practise identifying odd and even numbers.
