WEEK 2
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:
1. state which sign is greater (>) or which is less than (<)
2. Compare numbers using the > or < sign

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:
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
2. 36 < 88
3. 880 < 970
4. 75 > 44
5. 423 < 335
6. 280 > 106
7. 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.

Meaning of fractions
A fraction is one or more parts of a whole, which is divided into a number of
equal parts. The upper number is the numerator and is the part of the equally divided parts of a whole, the number own is the denominator and is equally divided parts of a whole.
⅟2means 1 part out of a whole, which is divided into 2 equal parts.

⅟4means 1 part out of a whole, which is divided into 4 equal parts.
3∕4means 3 parts out of a whole, which is divided into 4 equal parts.

2/3- the upper number is the numerator, the lower number is the denominator

Addition of 2-digit numbers with renaming
Addition of 2-digit numbers with renaming is solved by using:
the expanded method and,
the direct or short method.
Examples
Lets add 28 and 84 using the:
Expanded method
1. 2 8 = 20 + 8 2 8
+ 8 4 + 80 + 4 + 8 4
100 +12 = 100 + 10 + 2 1 1 2

In the units column, 8 + 4 = 12 units = 10 + 2, which is
1 ten and 2 units. Write 2 units in the units column and
carry 1 ten to the tens column. In the tens column,
1 + 2 + 8 = 11 tens = 10 tens + 1 ten, which is 1 hundred
and 1 ten. Write 1 ten in the tens column and carry
1 hundred to the hundreds column.

9 4 = 90 + 4 9 4
+ 8 9 = 80 + 9 + 8 9
+ 3 =170 + 10 + 3 1 8 3
=183
