LEGO Games stud collecting maths mission

Quick answer

You can use LEGO Games stud collecting to learn about place value by grouping your studs into tens and ones, just like when you count your coins or sort your toys.

Learning outcome

By the end of this page, you will be able to use LEGO studs to show numbers in tens and ones, and understand how place value works with numbers up to 100.

• I can group studs into tens and ones
• I can write numbers showing tens and ones
• I can compare numbers using tens and ones
• I can add two numbers using tens and ones

Why this matters

Understanding place value helps you count, add, and compare bigger numbers. When you play LEGO Games and collect studs, you are already using place value! It's like sorting your toys into boxes of ten and single items. This skill helps you in school with bigger maths, and in real life when you count money or measure things.

How it works

Place value means that the position of a digit shows its value. In a two-digit number, the first digit shows how many tens, and the second digit shows how many ones. For example, in the number 47, the 4 means 4 tens (that's 40), and the 7 means 7 ones (that's 7).

1. Count your LEGO studs
2. Group them into sets of ten
3. Count how many full groups of ten you have
4. Count how many single studs are left over
5. Write the number as tens and ones

Examples you can see

Imagine you collect 34 LEGO studs. Here's how you can show that with your studs:

• Make 3 groups of 10 studs each (that's 30 studs)
• Count 4 single studs left over
• Write it as: 3 tens and 4 ones
• Or write it as the number: 34

Here's a table showing how to write numbers in tens and ones:

Try it as a mini adventure

Imagine you are a LEGO explorer on a mission to collect studs from different LEGO Games. Your mission is to gather 72 studs. Here's how you can do it:

1. First, you collect 70 studs and put them into 7 groups of 10
2. Then you find 2 more studs
3. You write your number as: 7 tens and 2 ones
4. You can write it as: 72

Let's try another mission:

1. Find 45 studs
2. Group them into 4 groups of 10
3. Count 5 single studs
4. Write: 4 tens and 5 ones
5. Write: 45

Common mistakes

• Mistake: Thinking 56 is 5 tens and 6 ones, but writing it as 65
• Why it happens: Mixing up the order of tens and ones
• Fix: Always say the first digit as tens, and the second as ones
• Mistake: Counting 10 studs as 1 group, but forgetting to count the ones
• Why it happens: Not keeping track of how many single studs are left
• Fix: After making groups of ten, count the leftover studs carefully
• Mistake: Writing 10 as 1 one and 0 tens
• Why it happens: Confusing which digit is for tens and which is for ones
• Fix: Remember that 10 means 1 ten and 0 ones

Parent and carer guide

Help your child practice place value by using LEGO studs or any small objects like buttons or coins. Ask them to:

• Count a group of 20 to 50 studs
• Group them into tens
• Count how many tens and ones they have
• Write the number
• Compare two numbers using tens and ones

Ask questions like:

• How many tens do you have?
• How many ones are left over?
• Can you write that number?

Watch out for:

• Confusing the order of tens and ones
• Forgetting to count the leftover ones
• Writing numbers backwards

Remember to praise effort, not just correct answers. It's okay to make mistakes – they help you learn!

FAQ

What is place value?

Place value means that each digit in a number has a value based on its position. In a two-digit number, the first digit shows how many tens, and the second shows how many ones.

Why do we need to know place value?

Place value helps us understand how big numbers are, how to add and subtract them, and how to compare them. It's like having a system to keep track of things!

How can I practice place value at home?

You can use LEGO studs, counters, or even your fingers to group objects into tens and ones. Try writing numbers and seeing how many tens and ones they have.

What if I have a number with zero in it?

If there's a zero in the ones place, like 40, it means you have 4 tens and 0 ones. If there's a zero in the tens place, like 05, it means you have 0 tens and 5 ones.

Can I use place value with bigger numbers?

Yes! You can use place value with any number. For example, 123 has 1 hundred, 2 tens, and 3 ones. But for now, we're focusing on numbers up to 100.
