**WEEK 2**

**Subject: Mathematics**

**Class: Primary 3**

**Term: 1 ^{st} Term**

**Topic****: whole numbers from 1 to 999**

**Subbtitle****: Comparing numbers which are greater than (>) and those who are less than (<) numbers.**

**Learning Objectives****: At the end of this this lesson, pupils should be able to:**

**state which sign is greater (>) or which is less than (<)****Compare numbers using the > or < sign****List the characteristics of living things**

**Resources and materials:**

**Scheme of work**

**Online information**

**Instructional material****: Number chart****.**

**Building Background/connection to prior knowledge****: pupils are familiar with the topic in their previous classes.**

**CONTENT**

**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:**

- 777 is greater than 371
- 963 s greater than 290
- 570 is greater than 111
- 178 is less than 335
- 891 is less than 990
- 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

- 36 < 88
- 880 < 970
- 75 > 44
- 423 < 335
- 280 > 106
- 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**

**490 is…………. 217.****843 is ………….844****900 is ………….600****778 is…………..799**

**Complete with the correct symbol: <, > or =**

**150****…………****75 + 75**

** **

**552****…………****540**

** **

**280………..208**

** **

**165………..106**

** **

**43………….619**

**WRAP UP(CONCLUSION)**** Teacher goes over the topic once again for better understanding.**

**Assignment:**

**Arrange the following numbers in order from smallest to largest**

**a). 600, 200, 400, 300**

**b). 227, 285, 257, 239**

**c). 175, 65, 543, 100**

**Fill the gap with the correct symbol: < or >**

**a). 175……. 165 **

**b). 715……. 899**

**c). 503…… 465**

**d). 272……. 324**
