LEGO Games symmetrical models maths mission
A practical mini-mission using symmetrical models to practise symmetry through questions, examples and child-friendly challenges.
Quick answer
By building symmetrical LEGO models, you can learn how to identify and create shapes that are exactly the same on both sides of a line of symmetry.Learning outcome
By the end of this page, you will be able to build a LEGO model that is symmetrical, and you will understand how to find and draw lines of symmetry in shapes. Success signs:- You can build a LEGO model that looks the same on both sides of a line of symmetry.
- You can draw a line of symmetry through a shape or model.
- You can tell if a shape or model is symmetrical or not.
- You can create a symmetrical pattern using LEGO bricks.
Why this matters
Symmetry is all around us, and understanding it helps you see patterns in nature, art, and even in your own LEGO creations. When you build symmetrical models, you're not just making something look nice – you're learning how shapes and patterns work. This skill helps with problem-solving, creativity, and even helps you do well in maths at school. In LEGO games, symmetry can help you build better structures, make patterns, and even win games by creating balanced designs.How it works
Symmetry means that one side of a shape or model is exactly the same as the other side when you fold it along a line. This line is called the "line of symmetry". When you build with LEGO bricks, you can make models that are symmetrical by making sure both sides match perfectly. To build a symmetrical model:- Choose a line of symmetry (a line that goes through the middle).
- Build one side of your model.
- Make the other side match exactly.
- Check that both sides look the same.
Examples you can see
Let’s imagine you are building a LEGO robot. You can make it symmetrical by placing the same parts on both sides of the robot. Example 1: A simple robot- Place a red brick on the left side of the robot.
- Place a red brick on the right side.
- Place a yellow brick on the top of the robot.
- Place a yellow brick on the top of the robot on the other side.
- Build one petal on the left side.
- Build the same petal on the right side.
- Make sure the petals are the same size and shape.
Try it as a mini adventure
LEGO Symmetry Challenge: Build a Balanced Castle You are a LEGO architect! Your mission is to build a castle that is perfectly symmetrical. Here's how to do it:- Draw a line down the middle of your castle.
- Build the left side of the castle using bricks.
- Copy the exact same bricks on the right side of the line.
- Check that everything matches.
- Decorate your castle with flags or towers that are also symmetrical.
Common mistakes
- Mistake: Thinking that a model is symmetrical just because it looks similar on both sides.
Why it happens: Sometimes the shapes or sizes don’t match exactly.
Fix: Check that each part on one side is exactly the same as the part on the other side. - Mistake: Forgetting to draw the line of symmetry.
Why it happens: It’s easy to forget to think about the line.
Fix: Always draw a line down the middle before you start building. - Mistake: Building one side and then guessing what the other side should be.
Why it happens: You might not be careful about matching the bricks.
Fix: Build one side, then carefully copy it to the other side.
Parent and carer guide
Parents and carers can help by:- Encouraging children to think about the line of symmetry before they start building.
- Asking questions like, “Does this side look like the other side?”
- Helping children count how many bricks are on each side to check for symmetry.
- Using everyday objects like leaves, butterflies, or drawings to show symmetry.
- Letting children experiment with different lines of symmetry (vertical, horizontal, or diagonal).
Practice questions
- Which of these shapes is symmetrical? (You can draw or show with LEGO bricks.)
- A. A triangle with one side longer than the others
- B. A square with equal sides
- C. A rectangle with different length sides
- How many lines of symmetry does a square have?
- A. 1
- B. 2
- C. 4
- Can you build a symmetrical LEGO model using 10 bricks? Explain how.
- Answer: Yes, by making sure that one side has the same bricks as the other side.
- Which of these is NOT symmetrical?
- A. A heart shape
- B. A circle
- C. A triangle with no equal sides
- Draw a line of symmetry through a heart shape.
- Answer: Draw a vertical line down the middle of the heart.
FAQ
What is symmetry?
Symmetry means that one side of a shape or object is exactly the same as the other side when you fold it along a line. In LEGO games, symmetry helps you make balanced and beautiful models.
How can I check if my LEGO model is symmetrical?
Draw a line down the middle of your model. Then, check that the parts on one side match the parts on the other side exactly. If they do, it's symmetrical!
Can I use symmetry in other games or activities?
Yes! Symmetry is used in art, nature, and even in video games. You can find symmetrical patterns in flowers, butterflies, and buildings. It's a useful skill for many things.
Why is symmetry important in maths?
Symmetry helps you understand patterns and shapes. It's useful in geometry, art, and even in science. Learning symmetry builds your problem-solving and creative skills.
Can I make a symmetrical LEGO model with any number of bricks?
Yes! You can make a symmetrical model with any number of bricks. Just make sure that the bricks on one side match the bricks on the other side.
