Comparing numbers

Let study these two numbers:

481   316

Comparing the hundreds, we see that 4 is greater than 3.

Comparing the tens, we see that 8 is greater than 1.

Comparing the units, we see that 6 is greater than 1.

Since 4 hundred is greater than 3 hundreds, then 481 is greater than 316.

481 > 316

Examples:

1. 777 is greater than 371
2. 963 s greater than 290
3. 570 is greater than 111
4. 178 is less than 335
5. 891 is less than 990
6. 226 is less than 501

Using symbols to compare numbers

The symbols used to compare which number is ‘greater than’ or ‘less than’ are

called inequality symbols.

Note:  < less than     Looks like a folded left elbow.

> greater than      Looks like a folded right elbow.

Examples: 1.23 is less than 72. Using symbols, we can write this as 23 < 72

1. 36 < 88
2. 880 < 970
3. 75 > 44
4. 423 < 335
5. 280 > 106
6. 908 = 800 + 108

Strategies& Activities:

Step1: Teacher revises the previous topic.

Step2: Teacher introduces the new topic.

Step3: Teacher explains the new topic.

Step4: Teacher welcomes pupils questions.

Step5: Teacher evaluates the pupils.

Assessment & Evaluation:

Fill the gap with the greater than or lees than were appropriate

1. 490 is…………. 217.
2. 843 is ………….844
3. 900 is ………….600
4. 778 is…………..799

Complete with the correct symbol: <, > or =

1. 150…………75 + 75

1. 552…………540

1. 280………..208

1. 165………..106

1. 43………….619
