Hello, math friends! Today, we’re going to learn how to add fractions that have the same denominator. Do you know what a fraction is? A fraction is a way to show a part of something whole, like a piece of a pie.
Let’s start by remembering the parts of a fraction. A fraction has two numbers: the top number is called the numerator, and the bottom number is called the denominator. The denominator tells us how many equal parts the whole is divided into, and the numerator tells us how many of those parts we have.
When we add fractions with the same denominator, we keep the denominator the same and add the numerators. It’s easy! Let’s look at an example.
To add 2/8 + 3/8, we keep the denominator, which is 8, and add the numerators: 2 + 3 equals 5. So, the answer is 5/8.
Let’s practice with a fun story! Imagine a planet called Smiley Thon. This planet is divided into eight equal parts. Two-eighths of the planet are home to friendly aliens, and three-eighths are home to grumpy aliens.
What fraction of the planet is occupied by all the aliens? To find out, we add the fractions 2/8 + 3/8. We keep the denominator 8 and add the numerators: 2 + 3 equals 5. So, 5/8 of the planet is occupied by aliens.
Now, let’s visit another planet called Learnathon. This planet is divided into five equal parts. One-fifth of the planet has yellow water, three-fifths have purple water, and one-fifth has volcanic soil.
How much of Learnathon is covered with water? We add the fractions 1/5 + 3/5. We keep the denominator 5 and add the numerators: 1 + 3 equals 4. So, 4/5 of Learnathon is covered with water.
Thank you for learning with me! Now you know how to add fractions with the same denominator. Keep practicing, and you’ll become a math expert in no time. See you next time!
Fraction Pizza Party: Create your own fraction pizza using paper plates. Divide the plate into equal parts by drawing lines to represent the denominator. For example, if your denominator is 4, divide the plate into 4 equal parts. Color in some parts to represent the numerator. Now, make another fraction pizza with the same denominator and different numerator. Add the two pizzas together by counting the colored parts. How many parts are colored in total? What fraction does that represent?
Nature Fraction Hunt: Go on a nature walk and look for things that can be divided into parts, like leaves, flowers, or rocks. Choose an item and imagine it as a fraction. For example, if a leaf has 8 sections and 3 are brown, it can be represented as 3/8. Find another item with the same number of sections and create a new fraction. Add the two fractions together. What is the total fraction of the sections you observed?
Story Time Fractions: Create a short story about a planet with different creatures, just like Smiley Thon or Learnathon. Decide how many equal parts the planet is divided into and what fraction of the planet each type of creature occupies. Write down the fractions and add them together to find out how much of the planet is occupied by creatures. Share your story and fractions with a friend or family member!

Hello again, math friends! Today, I’m here so that we can 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 remember the parts of a fraction. This is the numerator, and this number is the denominator. Today, we’re going to take one step further: we’ll 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 we add the numerators: ( 2 + 3 ) equals 5. This result, the number 5, will be the numerator. So, the result is ( frac{5}{8} ).
Are you up for a challenge to practice a bit more? In the Smile and Learn universe, there’s 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 would represent the overall number of land occupied by all the aliens on the planet? To find out, we’ll need to add the fractions ( frac{2}{8} + frac{3}{8} ). Remember that the result will have to have the same denominator, which is 8. Now, to calculate the numerator, we’ll add the numerators: ( 2 + 3 ) equals 5. The result will be that ( frac{5}{8} ) of the land is occupied by aliens.
Will you help me 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 of the planet, and volcanic soil on one-fifth of the planet.
How much of the land on planet Learnathon is covered with water? To find out, we’ll need to add the fractions ( frac{1}{5} + frac{3}{5} ). First, in the result, we’ll keep the common denominator and then we’ll add the numerators: ( 1 + 3 ) equals 4. The result will be that ( frac{4}{5} ) of the land on the planet is covered with water.
