Hello, math friends! Today, we’re going to learn about adding and subtracting fractions that have the same denominator. It’s going to be fun and easy, so let’s get started!
Do you know what a fraction is? A fraction is a way to show a part of something whole. It has two parts: the top number is called the numerator, and the bottom number is called the denominator.
When we add fractions with the same denominator, we keep the denominator the same and just add the numerators. Let’s try an example:
Imagine you have ( frac{2}{8} ) and ( frac{3}{8} ). To add them, keep the denominator 8, and add the numerators: ( 2 + 3 = 5 ). So, ( frac{2}{8} + frac{3}{8} = frac{5}{8} ).
On a planet called Smiley Thon, there are friendly aliens on ( frac{2}{8} ) of the land and grumpy aliens on ( frac{3}{8} ) of the land. How much land do all the aliens occupy? Add the fractions: ( frac{2}{8} + frac{3}{8} = frac{5}{8} ). So, ( frac{5}{8} ) of the land is occupied by aliens.
Now, let’s learn how to subtract fractions with the same denominator. It’s just as easy! Keep the denominator the same and subtract the numerators.
For example, if you have ( frac{5}{9} ) and you want to subtract ( frac{2}{9} ), keep the denominator 9, and subtract the numerators: ( 5 – 2 = 3 ). So, ( frac{5}{9} – frac{2}{9} = frac{3}{9} ).
On Smiley Thon, there are apple trees and lemon trees in ( frac{6}{8} ) of the fields. If lemon trees are in ( frac{4}{8} ) of the fields, how many fields have apple trees? Subtract the fractions: ( frac{6}{8} – frac{4}{8} = frac{2}{8} ). So, ( frac{2}{8} ) of the fields have apple trees.
Now you know how to add and subtract fractions with the same denominator. Keep practicing, and you’ll become a math expert in no time. Great job, and see you next time!
Fraction Pizza Party: Create your own fraction pizzas using paper plates. Divide the plate into equal parts to represent fractions. For example, divide a plate into 8 slices. Color some slices to show different fractions, like ( frac{2}{8} ) or ( frac{3}{8} ). Practice adding and subtracting these fractions by combining or removing slices. How many slices do you have in total after adding or subtracting?
Fraction Scavenger Hunt: Go on a scavenger hunt around your home or classroom to find objects that can be divided into fractions. For example, find a chocolate bar and break it into equal pieces. If you have 8 pieces, take 3 pieces and see what fraction of the chocolate bar you have. Try adding or subtracting pieces with a friend and see how the fractions change.
Story Time with Fractions: Create a short story involving fractions. For example, imagine a picnic where you have a cake divided into 8 equal parts. Write a story about how you share the cake with friends, using fractions to describe how much each friend gets. How do the fractions change if more friends join or leave the picnic?

Hello again, math friends! Today, we will learn together how to add fractions with the same denominator.
Do you remember what a fraction is? A fraction is a number that indicates the division of a whole number into equal parts.
First, let’s review the parts of a fraction. This is the numerator, and this number is the denominator.
Today, we will take one step further and learn how to add fractions. To add fractions with the same denominator, we keep the common denominator and add the numerators. It’s very simple!
Let’s see an example: to add ( frac{2}{8} + frac{3}{8} ), we keep the common denominator, which is 8, and add the numerators: ( 2 + 3 = 5 ). The result is ( frac{5}{8} ).
Are you ready for a challenge to practice a bit more? In the Smile and Learn universe, there is a planet called Smiley Thon. This planet is divided into eight equal parts. Two-eighths of the planet are occupied by friendly aliens, and the remaining three-eighths are occupied by grumpy aliens.
What fraction represents the overall land occupied by all the aliens on the planet? To find out, we will add the fractions ( frac{2}{8} + frac{3}{8} ). Remember, the result will have the same denominator, which is 8. Now, to calculate the numerator, we add ( 2 + 3 = 5 ). The result is that ( frac{5}{8} ) of the land is occupied by aliens.
Now, let’s figure out something else. Our neighboring planet, Learnathon, is divided into five equal parts. There is yellow water on one-fifth of the planet, purple water on three-fifths, and volcanic soil on one-fifth.
How much of the land on planet Learnathon is covered with water? To find out, we will add the fractions ( frac{1}{5} + frac{3}{5} ). First, we keep the common denominator, and then we add the numerators: ( 1 + 3 = 4 ). The result is that ( frac{4}{5} ) of the land on the planet is covered with water.

Thank you for helping me! Now you know how to add fractions with the same denominator. Little by little, you are becoming math experts. Keep up the good work! See you around!
Hello again, math friends! We will continue learning about fractions. Today, we will learn how to subtract fractions with the same denominator.
Do you remember what a fraction is? A fraction is a number that indicates the division of a whole number into equal parts.
First, let’s review the parts of a fraction. This is the numerator, and this number is the denominator.
To subtract fractions with the same denominator, we keep the common denominator and only subtract the numerators. It’s very simple!
Let’s see an example: we need to solve the problem ( frac{5}{9} – frac{2}{9} ). The denominator stays the same, which is 9. Now we subtract the numerators: ( 5 – 2 = 3 ). The result of this math problem will be ( frac{3}{9} ).
Are you ready for another challenge? In the Smile and Learn universe, there is a planet called Smiley Thon. The planet is divided into eight equal parts. In six of these eight fields, they grow apple trees and lemon trees. If four of the eight fields are planted with lemon trees, how many fields are planted with apple trees?
To find out, we need to subtract fractions. We will subtract the total number of fields planted with fruit trees from the number of fields planted with lemon trees: ( frac{6}{8} – frac{4}{8} ). Remember to keep the same denominator, which is 8. Now, to calculate the numerator, we subtract ( 6 – 4 = 2 ). The result is that two of the eight fields are planted with apple trees, which is ( frac{2}{8} ).
Will you help me figure out something else? Planet Learn Turn is divided into five equal parts. On this planet, there are wooded areas and areas with houses. If they built houses on three of Learn Turn’s fields, how many parts of the planet are covered with woods?
To find the solution, we will need to subtract the fractions ( frac{5}{5} – frac{3}{5} ). First, we keep the same denominator, which is 5, and then we subtract the numerators: ( 5 – 3 = 2 ). The result is that two parts of Learn Turn are covered with woods, which is ( frac{2}{5} ).
