Presentation
These fractions we will use in our lesson. So listen
carefully so we know how to add fractions.

Discussion
So, our topic for today is about Addition of Similar
Fractions.
Today we will learn how to Add Simlilar Fraction Using
Number Line .
When we say "similar fractions," these are the fractions
that have the same denominator.
For example, 1/2 and 3/2
So these fractions have the same denominator. So we
can say that 1/2 and 3/2 are both similar fractions.
I will show you an example, look at this, class
2/8 + 3/8=
First, draw one fraction on the number line.
Let start with 2/8.
2/8 means 2 out of 8 parts
9, Teacher
Next , look at the second fraction we’re adding.
1/6 means 3 out of 8 parts.
Adding 2/8 to 3/8 means you jump forward 1 step from
3/6.
5/8, Ma’am.
Class, where we landed?
Very Good!, We landed on 5/8. That’s our sum.
Let’s have another example;
3/6+1/6 = ?
3 out of 6 parts, teacher.
What does 3/6 mean?
1 out of 6 parts
How about 1/6?
Adding 3/6 to 1/6 means “jumping” forward 1 step from
3/6
We landed on 4/6. That’s our sum.
Perfect class!!
C.Post Developmental Activities
E. Generalization
Class, how do you add fractions on a number line?
Very good!
First, draw one fraction on the
number line.
To add fractions on a number line, remember these
things:
1.
The fractions must have the same
denominators.
2.
Use the number line only to add fractions.
3.
Jump forward from the first fraction. The
numerator of the fraction you’re adding will tell you the
number of steps you need to jump.
The number you land on is in the answer.
IV. Application
Let’s Try!
Solve the word problems by adding similar fraction
using number line.
1.
2/6 + 3/6 =
2.
4/8 + 3/8 =
V. Assignment
Answer the following and write it in your assignment
notebook.
1. 3/8 + 4/8 =
2. 1/4+2/4 =
