**Content :**

Ordering of numbers simply means the arrangement of numbers based on thier values of magnitude. It is the arrangement of figures that is based on the size values of this those figures.

Pupils, which figure is bigger between 5 and 81. Answer 81 is bigger

Which figure is bigger between 8 and 14

Answer 14 is bigger than 8

Pupils, please kindly raise up your right 👉 hand 🖐️, good. When the symbol is pointing 👉 to the right hand, we call that symbol GREATER THAN (>)

We can use the symbol of greater than in mathematics to show the values of numbers

Samples :

1.Figure 21 is greater than figure 8

We can write this in symbol by saying 21 > 8

2.Number 67 is greater than number 12

We can write this in symbols by saying

67 > 12

3. Digit 88 is bigger than digit 76

We can write this in symbol by saying

88 > 76

Pupils please kindly raise up your left hand, when the symbol is pointing to your left hand, we call that symbol less than or smaller than (<)

Examples.

(A)8 is smaller then 34

8 < 34

(b) someone that is 7 years old will be smaller than someone that is 17 years old.

We can use symbols to write out this one by saying 7 < 17

(c) 56 is smaller than 101

We can use the symbol to write out this by saying 56 < 101

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.
