LEGO Games instruction errors maths mission

Quick answer

When you play LEGO Games, sometimes the instructions have errors. You can fix these errors by checking what you're building, counting carefully, and using logic to spot what’s wrong.

Learning outcome

By the end of this page, you will be able to find and fix errors in LEGO building instructions by checking your work, counting parts, and using clues from the pictures.

• You can look at a LEGO set and spot if something is missing or wrong.
• You can explain why a part doesn’t fit or why a step is wrong.
• You can fix small mistakes in a LEGO building plan by thinking carefully.
• You can use your counting and logic skills to make sure your LEGO creation matches the instructions.

Why this matters

LEGO Games are more than just fun—they help you learn important maths skills like counting, checking your work, and solving problems. When you fix errors in instructions, you're using logic and reasoning. These skills are useful not just in LEGO, but in school, in puzzles, and even in real life. You’ll be better at spotting mistakes in your homework or in your own plans.

How it works

When you build with LEGO, sometimes the instructions have small mistakes. You can find these mistakes by:

1. Looking carefully at each step and checking if it makes sense.
2. Counting the pieces you have to make sure they match the instructions.
3. Comparing what you're building with the picture in the instruction book.
4. Thinking about what would happen if you did something wrong, like putting a piece in the wrong place.

Examples you can see

Imagine you’re building a LEGO spaceship. The instruction says: “Put 4 red bricks on top of the base.” But when you look at your bricks, you only have 3 red bricks. That’s a mistake! You can fix it by:

• Checking if you missed a red brick in your box.
• Looking at the instruction again to see if it says “3” instead of “4”.
• Adding one more red brick to finish the spaceship.

Another example: You're building a castle. The instruction says “Put 2 yellow bricks on the left wall.” But when you check, you see 3 yellow bricks on the right wall. You can fix this by moving the extra brick to the left wall.

Adventure: The LEGO Mystery Mission

You are a LEGO detective! Your mission is to find and fix the errors in a set of LEGO instructions. Here’s your mission:

1. Look at the first step of the instructions for a LEGO car.
2. Count how many pieces you have for that step.
3. Check if the number matches the instruction.
4. If not, decide what to do next.
5. Move to the next step and repeat the process.

For example, the instruction says: “Use 5 blue bricks.” If you only have 4, you can:

• Ask a parent or friend to help you find the missing brick.
• Look at your box again to see if you missed a blue brick.
• Change the instruction to say “Use 4 blue bricks” if you can’t find the 5th one.

Common mistakes

• Mistake: Not checking if the number of bricks matches the instruction.
• Why it happens: Sometimes we are in a hurry and don’t double-check.
• Fix: Always count your pieces before starting a step.

• Mistake: Thinking a picture shows the wrong part.
• Why it happens: Instructions can be confusing or unclear.
• Fix: Compare the picture with what you are doing. If it doesn’t match, ask a grown-up for help.

• Mistake: Not looking at the whole instruction before starting.
• Why it happens: It’s easy to get excited and start building without reading all the steps.
• Fix: Read the whole instruction first, then start building one step at a time.

Parent and carer guide

As a parent or carer, you can help your child by:

• Encouraging them to slow down and check their work.
• Asking questions like, “Does this look right?” or “How many pieces do you need?”
• Letting them try to fix the mistake themselves before helping.
• Helping them to understand why a step doesn’t work.
• Not rushing them—LEGO is about patience and problem-solving.

Remember, mistakes are part of learning. Your child might not get it right the first time, and that’s okay. It’s a chance to practice their logic and reasoning skills.

Practice questions

1. Instruction says: “Use 3 green bricks.” You have 4. What should you do?
