Alien planet maths quest: fractions
A story-led junior maths adventure using strange number systems and gravity jumps to split food, maps and treasure into equal parts.
Quick answer
Fractions are parts of a whole, and you can split things into equal parts to understand them. On an alien planet, you might need to divide food, treasure, or maps into equal pieces using strange number systems and gravity jumps!
Learning outcome
By the end of this page, you will understand how to split things into equal parts and use simple fractions to show how much of the whole you have.
- You can identify halves, quarters, and thirds of shapes and objects.
- You can share items equally between friends or groups.
- You can use fraction language like "one half", "one quarter", and "one third".
- You can solve simple fraction problems using drawings or real objects.
Why this matters
Fractions help you share things fairly, understand parts of a whole, and solve problems in everyday life. Whether you're splitting a pizza, sharing your allowance, or helping your alien friend divide treasure, fractions are super useful!
How it works
Fractions are all about parts of a whole. The top number (numerator) tells how many parts you have. The bottom number (denominator) tells how many equal parts the whole is split into.
Let's imagine you're on an alien planet where everything is different. You find a strange fruit and want to share it equally with your alien friend.
- First, you must decide how many equal parts to split the fruit into.
- Then, you count how many parts you get.
- Finally, you say how many parts you have using fraction words.
Examples you can see
Let's look at some fun examples from an alien planet!
Example 1: Sharing a Strange Fruit
You find a fruit that looks like a purple circle. You want to share it equally between you and your alien friend. You cut it into 2 equal parts.
- Each part is one half of the fruit.
- Written as a fraction: 1/2
Example 2: Dividing Alien Treasure
You discover a treasure chest with 8 shiny rocks. You want to split them equally among 4 aliens.
- Each alien gets 2 rocks.
- Each alien gets two eighths of the treasure.
- Written as a fraction: 2/8
Example 3: Mapping the Alien Planet
Your map is a rectangle. You split it into 4 equal parts to show different areas.
- Each part is one quarter of the map.
- Written as a fraction: 1/4
Example 4: Gravity Jump Challenge
You're jumping on an alien planet with different gravity. You make 6 jumps and land in 3 equal sections.
- Each section is one third of your journey.
- Written as a fraction: 1/3

Alien Planet Fraction Quest
You are on an alien planet with your robot friend. You find a treasure map, a bag of space food, and a strange alien fruit. You must split everything fairly to share with your team of 4 aliens.
Step 1: The Treasure Map
Your map is a rectangle. You must split it into 4 equal parts for your team. How many parts does each alien get?
Step 2: Space Food
You have 12 pieces of alien food. You want to share them equally between 4 aliens. How many pieces does each alien get?
Step 3: The Strange Fruit
You find a fruit that you want to split into 3 equal parts. How much of the fruit does each alien get?
Step 4: Gravity Jump
You must jump 10 times to reach the treasure. You want to split your jumps into 5 equal sections. How many jumps are in each section?
Common mistakes
- Mistake: Thinking that 1/2 and 1/4 are the same size.
- Why it happens: Confusing the numbers in the fraction.
- Fix: Use drawings to show that 1/2 is bigger than 1/4.
- Mistake: Counting the whole as part of the fraction.
- Why it happens: Not understanding that the denominator shows the total number of equal parts.
- Fix: Always count the equal parts, not the whole.
- Mistake: Adding fractions by adding both numerators and denominators.
- Why it happens: Thinking fractions are like regular numbers.
- Fix: Remember that we only add numerators when denominators are the same.
Parent and carer guide
Help your child learn fractions by:
- Using everyday objects like pizza, cakes, or fruit to practice sharing.
- Asking questions like, "If we split this cake into 4 pieces, how much is each piece?"
- Encouraging them to draw fractions to help understand.
- Playing games like "fraction matching" with cards or objects.
- Using fraction language daily: "half", "quarter", "third" instead of just "some".
Remember: fractions are about sharing fairly. Don't worry if they get confused at first – it's normal!
Practice questions
- Draw a circle and split it into 2 equal parts. What fraction is each part?
- You have 6 apples and want to share them equally between 3 friends. How many apples does each friend get?
- Split a rectangle into 4 equal parts. What fraction is each part?
- You have 10 cookies and want to split them into 5 equal groups. What fraction of the cookies is in each group?
- Draw a triangle and split it into 3 equal parts. What fraction is each part?
Answers:
- Each part is 1/2
- Each friend gets 2 apples
- Each part is 1/4
- Each group has 2 cookies, which is 2/10 or 1/5
- Each part is 1/3
FAQ
What is a fraction?
A fraction shows a part of a whole. It has a top number (numerator) and a bottom number (denominator).
How do I write a fraction?
You write a fraction by placing the number of parts you have on top, and the total number of equal parts on the bottom.
What does "one half" mean?
"One half" means one of two equal parts. It is written as 1/2.
Can I share 8 cookies between 4 people?
Yes! Each person gets 2 cookies, which is 2/8 or 1/4 of the cookies.
Why do we need fractions?
Fractions help us share things fairly, measure parts of a whole, and solve problems in real life.
