Numerators are the numbers that are written on top of Fractions while denominators are the numbers that are written under the Fractions.
Given a fraction one over four (1/4)
One is the numerator
Four is the denominator.
In this lesson we want to discus about the addition of Fractions with the same denominators.
When ever we want to add up Fractions with the same denominators, we just sum up the Numerators and the value of the denominators we not change because it was just the Numerators that we added together.

1.Add up 1/9 and 2/9
Solution. You will need to sun up the Numerators which are 1 and 2
1 plus 2 equal to 3
Answer equals to 3/9
Find the sum of 3/8 and 2/8
3+2 = 5
Answer = 5/8
The topic is presented step by step
The class teacher revises the previous topics
He introduces the new topic
The class teacher allows the pupils to give their own examples and he corrects them when the needs arise
