This topic introduces the concept of ‘greater than’, ‘less than’ and ‘equal to’, to the kids.

They will determine if one number is the same as or smaller than or bigger than another number.

GREATER THAN

We love to introduce this lesson to the kids in a very simple way. At their age, we do not want to introduce the greater than and less than signs

Rather, we teach them using numbers on a straight line.

Example 1:

1          2          3          4          5          6          7          8          9          10

At this stage, the kids should be able to recognize numbers 1- 10.

You will use the concept of ‘after’ and ‘before’ to teach greater than and less than. Here, we are dealing with greater than.

Ask the kids which number is greater than 9?

Teach them that, any number in front (after) 9, is greater than 9. In this case, the number greater than 9 is 10.

EXAMPLE 2: What are the numbers greater than 5?

Teach them that all the numbers in front of 5 are greater than 5.

In answering this question, the kids should mention 6, 7, 8, 9, 10 as the numbers greater than 5.

The beauty of this pattern is that, once the kids know the order of the numbers, it will be easy to know which number is greater than or less than.

If you ask: 5 and 7, which is greater?

For easy reasoning, the kids can write 1- 10 on a paper, from the order, they can easily tell that 7 is greater than 5.

##### LESSON : LESS THAN

Less than will be taught using the concept of ‘before’ or ‘back’.

All the numbers before the chosen number or at the back of the chosen number are less than the chosen number.

EXAMPLE 1:

What number is less than 2?

The kids should say 1 is less than 2 because 1 is before 2 or 1 is at the back of 2.

##### 1       2       3       4       5       6       7       8       9       10

EXAMPLE 2: What are the numbers less than 5? They should say- 4, 3, 2, 1.

It’s always better for them to start with the number closest to the chosen number.

8 and 3 which is less?

3 is less than 8

Presentation

The topic is presented step by step

Step 1:

The class teacher revises the previous topics

Step 2.

He introduces the new topic

Step 3:

The class teacher allows the pupils to give their own examples and he corrects them when the needs arise

Evaluation :

FILL THE GAPS

1. Which number is bigger 8 or 13
2. Which number is smaller 8 or 4
3. Which number is bigger 8 or 1
4. Which number is smaller 3 or 8

Conclusion :

The class teacher wraps up or conclude the lesson by giving out short note to summarize the topic that he or she has just taught.

The class teacher also goes round to make sure that the notes are well copied or well written by the pupils.

He or she does the necessary corrections when and where  the needs arise.
