Wizard school maths quest: ratio
A story-led junior maths adventure using potions, spells and pattern magic to mix recipes, scale drawings and compare quantities.
Quick answer
Ratios help us compare how much of one thing there is compared to another thing. In Wizard School, ratios help wizards mix potions correctly, build magical structures, and understand spells. You can think of ratios like sharing or comparing things in a special way.
Learning outcome
By the end of this page, you will understand how to use ratios to compare amounts and solve simple problems in magic and real life.
- You can describe ratios using words like "for every" or "to"
- You can match ratios to pictures or objects
- You can use ratios to share or compare things fairly
- You can solve simple ratio problems using drawings or counting
Why this matters
Ratios are super important for wizards in magic school! They help mix the perfect potion, build the right-sized tower, or divide magical treats fairly. You use ratios every day when you share snacks, follow recipes, or play games with friends. Understanding ratios helps you solve problems in a smart way, not just guess.
How it works
Ratios compare two or more amounts. We write them like this: 3 to 5 or 3:5. This means for every 3 of one thing, there are 5 of another. Let's use a wizard's potion recipe to understand.
- First, we count how many ingredients we have
- Then we write how many of each ingredient there are
- We use a colon (:) to show the comparison
- We can simplify the ratio if needed
Examples you can see
Imagine a wizard's spell needs 2 drops of dragon tears and 3 drops of unicorn horn powder. The ratio is 2:3. That means for every 2 drops of dragon tears, we need 3 drops of unicorn horn powder.
| Ingredient | Amount | Ratio |
|---|---|---|
| Dragon tears | 2 drops | 2:3 |
| Unicorn horn powder | 3 drops | 2:3 |
Let's try another example with a wizard's magic garden. The garden needs 4 red flowers and 6 blue flowers. The ratio is 4:6. We can simplify this to 2:3 because both numbers can be divided by 2.
Here's a fun way to imagine ratios: if you have 5 magic stones and 10 spell books, the ratio is 5:10 or 1:2. That means for every 1 stone, there are 2 books.

Wizard School Potion Challenge
Wizard School is having a Potion Competition! You must mix the perfect magic potion using the correct ratio of ingredients.
Task: Mix a potion using 3 parts water and 1 part glowing powder.
4th time: ? drops of water
5th time: ? drops of glowing powder
7th time: ? drops of water
8th time: ? drops of glowing powder
9th time: ? drops of water
10th time: ? drops of glowing powder
Now, if you use 12 drops of water, how many drops of glowing powder do you need?
Answer: 4 drops of glowing powder
Common mistakes
- Mistake: Writing the ratio backwards, like 1:3 instead of 3:1
Why it happens: Confusing which item is first in the comparison
Fix: Always check which item comes first in the story or problem - Mistake: Forgetting to simplify ratios
Why it happens: Not knowing that 4:8 and 1:2 show the same relationship
Fix: Divide both numbers by the same number to find a simpler version - Mistake: Thinking ratios are just addition or subtraction
Why it happens: Mixing up ratio with other maths operations
Fix: Remember ratios compare, not add or subtract
Parent and carer guide
Help your child understand ratios by using everyday examples like:
- Sharing snacks: "For every 2 cookies, you get 1 apple"
- Cooking: "This recipe uses 3 cups of flour for every 1 cup of sugar"
- Playing games: "For every 3 red marbles, there are 2 blue ones"
Ask questions like: "What is the ratio of red to blue?" or "If we double the red, what happens to the blue?"
Remember, ratios don't need to be complicated. Keep it simple and fun!
Practice questions
- What is the ratio of 6 apples to 9 oranges? Answer: 2:3
- Write the ratio of 4 magic wands to 8 spell books. Answer: 1:2
- If there are 10 red gems and 15 blue gems, what is the ratio? Answer: 2:3
- How many drops of magic dust are needed if you use 12 drops of water and the ratio is 3:1? Answer: 4 drops
- What is the simplified ratio of 8 magic stones to 12 spell books? Answer: 2:3
FAQ
What is a ratio?
A ratio compares how much of one thing there is compared to another. It's like saying "for every 3 red balls, there are 2 blue balls."
How do I write a ratio?
We write ratios using a colon (:). For example, 5:3 means 5 of one thing to 3 of another.
Can ratios be simplified?
Yes! Just like fractions, we can make ratios simpler by dividing both numbers by the same amount. For example, 6:9 simplifies to 2:3.
Where do we use ratios in real life?
We use ratios when sharing food, following recipes, dividing toys, or playing games. They help us share fairly and understand how things relate to each other.
How can I help my child practice ratios?
Use everyday situations like cooking, sharing snacks, or playing games. Ask your child to describe ratios in their world and make up simple problems together.
