Hello, math friends! Today, we’re going to explore the exciting world of fractions. We’ll learn how to add, subtract, multiply, and divide fractions. Let’s dive in!
Do you know what a fraction is? A fraction shows how a whole is divided into equal parts. It has two parts: the top number is the numerator, and the bottom number is the denominator.
When adding fractions with the same denominator, you keep the denominator and add the numerators. It’s easy!
For example, to add 2/8 + 3/8, keep the denominator 8 and add the numerators: 2 + 3 = 5. So, the answer is 5/8.
Imagine a planet called Smiley Thon, divided into eight parts. Two parts have friendly aliens, and three parts have grumpy aliens. How much of the planet do the aliens occupy? Add 2/8 + 3/8 to find out: 5/8 of the planet is occupied by aliens.
To subtract fractions with the same denominator, keep the denominator and subtract the numerators.
For example, to solve 5/9 – 2/9, keep the denominator 9 and subtract the numerators: 5 – 2 = 3. So, the result is 3/9.
On Smiley Thon, six fields grow apple and lemon trees. If four fields have lemon trees, how many have apple trees? Subtract 6/8 – 4/8 to find out: 2/8 of the fields have apple trees.
To multiply fractions, multiply the numerators and the denominators.
For example, to multiply 1/2 by 3/5, multiply the numerators: 1 × 3 = 3, and the denominators: 2 × 5 = 10. So, 1/2 × 3/5 = 3/10.
Try another example: 2/3 × 1/5. The numerators multiply to 2, and the denominators multiply to 15, so the result is 2/15.
When dividing fractions, multiply the numerator of the first fraction by the denominator of the second fraction for the new numerator. Multiply the denominator of the first fraction by the numerator of the second fraction for the new denominator.
For example, to divide 3/5 by 1/2, multiply 3 × 2 = 6 for the numerator, and 5 × 1 = 5 for the denominator. So, 3/5 ÷ 1/2 = 6/5.
Try another example: 1/5 ÷ 1/3. The result is 3/5.
We’ve learned so much about fractions today! Keep practicing, and you’ll become a fraction expert in no time. If you want to learn more, check out fun educational channels like Smile and Learn. Happy learning!
Fraction Pizza Party: Create your own fraction pizza using paper plates. Divide the plate into equal parts to represent fractions. For example, divide it into 8 slices. Use crayons or markers to color some slices to represent different fractions. For instance, color 3 out of 8 slices to show 3/8. Try adding or subtracting slices with a friend to see how fractions work in a fun and tasty way!
Fraction Hunt: Go on a fraction hunt around your home or classroom. Look for objects that can be divided into equal parts, like a chocolate bar or a set of building blocks. Identify the fractions you see. For example, if a chocolate bar has 4 equal pieces and you eat 1, what fraction of the chocolate bar did you eat? Share your findings with the class and see who found the most interesting fractions!
Story Time with Fractions: Create a short story using fractions. Imagine a world where everything is divided into fractions, like the planet Smiley Thon. Write about a day in the life of a character who uses fractions to solve problems. For example, how do they share a pie with friends or divide treasure among pirates? Share your story with the class and see how creative you can be with fractions!

Hello again, math friends! Today, we’re going to learn 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: the top number is the numerator, and the bottom number is the denominator.
To add fractions with the same denominator, we keep the common denominator and add the numerators. It’s very simple!
For example, to add ( frac{2}{8} + frac{3}{8} ), we keep the common denominator, which is 8, and add the numerators: ( 2 + 3 = 5 ). So, the result is ( frac{5}{8} ).
Now, let’s practice a bit more. In the Smile and Learn universe, there’s a planet called Smiley Thon, which is divided into eight equal parts. Two-eighths of the planet are occupied by friendly aliens, and three-eighths by grumpy aliens. What fraction represents the overall land occupied by all the aliens?
To find out, we add ( frac{2}{8} + frac{3}{8} ). The common denominator is 8, and the numerators add up to 5, so ( frac{5}{8} ) of the land is occupied by aliens.
Next, let’s look at another planet, Learnathon, which 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 add ( frac{1}{5} + frac{3}{5} ). The common denominator is 5, and the numerators add up to 4, so ( frac{4}{5} ) of the land is covered with water.
Now you know how to add fractions with the same denominator! Keep up the good work!

Hello again, math friends! Today, we’re going to learn how to subtract fractions with the same denominator.
To subtract fractions with the same denominator, we keep the common denominator and subtract the numerators.
For example, to solve ( frac{5}{9} – frac{2}{9} ), the denominator stays the same at 9, and we subtract the numerators: ( 5 – 2 = 3 ). So, the result is ( frac{3}{9} ).
In the Smile and Learn universe, there’s a planet called Smiley Thon, which 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?
We need to subtract ( frac{6}{8} – frac{4}{8} ). The common denominator is 8, and the numerators subtract to 2, so ( frac{2}{8} ) of the fields are planted with apple trees.
On another planet, Learn Turn, which is divided into five equal parts, if they built houses on three of the fields, how many parts of the planet are covered with woods?
We subtract ( frac{5}{5} – frac{3}{5} ). The common denominator is 5, and the numerators subtract to 2, so ( frac{2}{5} ) of the planet is covered with woods.
Now you know how to subtract fractions with the same denominator!

Hello again, friends! Today, we’re going to learn how to multiply fractions.
To multiply fractions, we multiply the numerators together and the denominators together.
For example, to multiply ( frac{1}{2} ) by ( frac{3}{5} ), we multiply the numerators: ( 1 times 3 = 3 ), and the denominators: ( 2 times 5 = 10 ). So, ( frac{1}{2} times frac{3}{5} = frac{3}{10} ).
Let’s try another example: ( frac{2}{3} times frac{1}{5} ). The numerators multiply to 2, and the denominators multiply to 15, so the result is ( frac{2}{15} ).
Now you know how to multiply fractions!

Hello again, friends! Today, we’re going to learn how to divide fractions.
When we divide fractions, we multiply the numerator of the first fraction by the denominator of the second fraction to find the numerator of the product. To find the denominator, we multiply the denominator of the first fraction by the numerator of the second fraction.
For example, to divide ( frac{3}{5} ) by ( frac{1}{2} ), we multiply ( 3 times 2 = 6 ) for the numerator, and ( 5 times 1 = 5 ) for the denominator. So, ( frac{3}{5} div frac{1}{2} = frac{6}{5} ).
Let’s try another example: ( frac{1}{5} div frac{1}{3} ). The result is ( frac{3}{5} ).
Now you know how to divide fractions!
