Super Mario Maker symmetrical castles maths mission
A practical mini-mission using symmetrical castles to practise symmetry through questions, examples and child-friendly challenges.
Quick answer
You can create symmetrical castles in Super Mario Maker and use them to learn about symmetry – where one side is a mirror image of the other side. By building and checking castles, you'll understand how shapes and patterns can be balanced and fair.
Learning outcome
By the end of this page, you will be able to identify and create symmetrical shapes and patterns in your Super Mario Maker castles, and explain how symmetry works in real life.
- I can find a line of symmetry in a shape or castle
- I can build a castle that is the same on both sides of a line
- I can tell if a pattern or shape is symmetrical or not
- I can use symmetry to make my castle look balanced and neat
Why this matters
Symmetry is all around us – in nature, buildings, art, and even in video games! Understanding symmetry helps you see patterns, build better designs, and solve puzzles. In Super Mario Maker, symmetry makes your castle look neat and balanced. It also helps you plan how to build more efficiently, and it makes your castle look like a real castle – not a lopsided mess!
How it works
Symmetry means that one side of something is a mirror image of the other side. If you fold a shape in half, both sides match perfectly. In Super Mario Maker, you can use symmetry to make your castle look fair and tidy.
- Draw a line down the middle of your castle
- Check if the left side matches the right side
- If they match, your castle is symmetrical
- If they don’t match, try again and fix it
Examples you can see
Let’s imagine you’re building a castle in Super Mario Maker. Here are some examples of what a symmetrical castle might look like:
| Castle Part | Symmetrical? | Why? |
|---|---|---|
| Two towers on either side | Yes | They are the same size and shape |
| One tower on the left, two on the right | No | They don’t match on both sides |
| A flag on the left, a flag on the right | Yes | They are in the same place, same size |
| A window on the left, a door on the right | No | They are different shapes and positions |
You can also draw a line of symmetry down the middle of your castle. If you fold it in half, both sides match perfectly. Try drawing a line down the middle of a castle you’ve made and see if both sides are the same.
Try it as a mini adventure
Imagine you are a castle builder in Super Mario Maker. Your mission is to build a castle that is perfectly symmetrical. Here’s your adventure:
- Start by drawing a line down the middle of your castle
- Build the left side of the castle
- Now, copy the left side exactly to the right side
- Check if both sides match perfectly
- If they don’t match, adjust one side to match the other
- Once it’s symmetrical, your castle is ready for the kingdom!
Challenge yourself to make a castle with more than one line of symmetry – like a castle with two towers, a flag, and a door on each side.
Common mistakes
- Mistake: Thinking that a castle is symmetrical if it just has the same shapes on both sides.
- Why it happens: Kids sometimes confuse shape with position. A castle with two towers on each side might look symmetrical, but if one is taller or higher, it’s not really symmetrical.
- Fix: Check that the shapes are the same size, shape, and position on both sides of the line of symmetry.
- Mistake: Not using a line to check symmetry.
- Why it happens: It’s hard to see if something is balanced without a guide.
- Fix: Always draw a line down the middle and check both sides match exactly.
- Mistake: Building a castle that is not symmetrical on purpose to make it look "cool".
- Why it happens: Kids might think asymmetry looks more interesting.
- Fix: Explain that symmetry makes things look balanced and fair – like a perfectly built castle!
Parent and carer guide
Help your child by:
- Building a symmetrical castle together in Super Mario Maker
- Pointing out symmetry in real life – like butterflies, flowers, or buildings
- Encouraging them to draw a line down the middle of their castle and check both sides
- Letting them try different shapes and see what works
- Reinforcing that symmetry means both sides are the same
- Not worrying if it takes a few tries to get it right – that’s how learning works!
Ask questions like: “What do you notice about the towers on each side?” or “Can you find the line of symmetry?” These help your child think more deeply about symmetry.
Practice questions
- Is a castle with two towers on the left and one tower on the right symmetrical? Why or why not?
- Draw a line of symmetry on a castle that has a flag on the left and a flag on the right.
- What happens if you add a window on the left side but not on the right side?
- Can you name three things in your home that are symmetrical?
- How can you make sure your castle is perfectly symmetrical in Super Mario Maker?
Answers:
- No, because the towers are not the same on both sides.
- Draw a vertical line down the middle of the castle.
- The castle would not be symmetrical because the sides would not match.
- Answers will vary – e.g. a mirror, a door, a butterfly.
- Use a line of symmetry to check both sides, and copy the left side exactly to the right side.
FAQ
What is symmetry?
Symmetry means that one side of something is a mirror image of the other side. If you fold it in half, both sides match perfectly.
Why do we use symmetry in Super Mario Maker?
Symmetry makes your castle look neat, balanced, and like a real castle. It also helps you build more efficiently.
Can a castle be symmetrical with more than one line of symmetry?
Yes! A castle with two towers, a flag on each side, and a door on each side can have more than one line of symmetry.
How can I practice symmetry at home?
You can look for symmetrical things around your house, draw symmetrical shapes, or build symmetrical castles in Super Mario Maker.
What if my castle doesn’t look symmetrical?
That’s okay! Try again by checking each side and copying the left side to the right side exactly.
