Train Platforms maths mission

A junior real-world challenge using train platforms to practise ordinal numbers without feeling like a worksheet.

Quick answer

Train Platforms maths mission is a fun way to learn about ordinal numbers by finding your place on a train platform. You'll use words like "first", "second", "third", and so on to describe where you are in a line or queue.

Learning outcome

By the end of this page, you will be able to describe positions in a line or queue using ordinal numbers from first to twelfth, and understand how to use these words to solve simple real-world problems. Success signs:
  • You can say which position you are in a queue or line
  • You can tell someone which platform your train is on
  • You can use ordinal numbers to describe where things are in order
  • You can solve simple problems using ordinal numbers

Why this matters

Ordinal numbers help us understand where we are in a line, queue, or sequence. Whether you're waiting for a train, lining up for lunch, or playing a game, knowing your position helps you move smoothly and understand your place in a group. This skill is useful for school, sports, cooking, and everyday life. When you understand ordinal numbers, you're better at following directions, planning, and solving problems.

How it works

Ordinal numbers show the position or order of things in a line or group. They tell us "which one" or "where one is" in a sequence. For example:
  1. First
  2. Second
  3. Third
  4. Fourth
  5. Fifth
  6. Sixth
  7. Seventh
  8. Eighth
  9. Ninth
  10. Tenth
  11. Eleventh
  12. Twelfth
These numbers help us describe where we are in a line. The first person is at the front, the second person is just behind them, and so on. When you're on a train platform, you can say you're "first in line" or "third from the back".

Examples you can see

Let's imagine you're at a train station with a queue of people waiting for the 10:30 train: Example 1: Queue at the platform
  • Person A is first in line
  • Person B is second in line
  • Person C is third in line
  • Person D is fourth in line
Example 2: Train platform positions
  • Platform 1 is the first platform
  • Platform 2 is the second platform
  • Platform 3 is the third platform
  • Platform 4 is the fourth platform
Example 3: Train carriages
  • The first carriage is at the front of the train
  • The second carriage is just behind the first
  • The third carriage is behind the second

Try it as a mini adventure

Train Platform Challenge You are on a train journey and need to find your platform. Here's your mission: 1st time: You are at the station with 12 people in front of you in line. What position are you in? 2nd time: The platform numbers are 1 to 12. Your train is on platform 7. What position is platform 7? 3rd time: You are in the second carriage of the train. What position is that? 4th time: You are the third person in the queue. What position are you in? 5th time: You are at platform 12. What position is that? 6th time: You are in the last carriage of the train. What position is that? Answer the adventure questions: 1st time: You are in the 13th position 2nd time: Platform 7 is the seventh platform 3rd time: The second carriage is the second from the front 4th time: You are in the third position 5th time: Platform 12 is the twelfth platform 6th time: The last carriage is the twelfth carriage

Common mistakes

  • Mistake: Saying "second" instead of "second to last"
    Why it happens: Confusing which position is second from the back
    Fix: Count from the back to see which position is second from the end
  • Mistake: Getting confused between "first" and "first from the back"
    Why it happens: Not thinking about counting from different directions
    Fix: Practice counting from both the front and back to understand the difference
  • Mistake: Thinking that "twelfth" means you're at the front
    Why it happens: Mixing up ordinal numbers with cardinals
    Fix: Remember that "twelfth" means you're in the 12th position, not the first

Parent and carer guide

As a parent or carer, you can help your child learn ordinal numbers in these ways:
  • Practice with everyday lines: When waiting in a shop or at the bus stop, ask your child to tell you their position in the queue
  • Use train platforms at home: Create a simple line with toys or family members and ask your child to describe who is first, second, third, etc.
  • Play ordinal games: Use ordinal number cards or online games to make learning fun
  • Encourage counting from different directions: Ask your child to count from the front and then from the back of a line
  • Be patient: It's normal for children to mix up positions at first. Practice makes progress!

Practice questions

  1. What position are you in if you are the fifth person in a queue?
  2. If there are 10 people in front of you, what position are you in?
  3. Which platform is the sixth platform?
  4. You are in the third carriage of a train. What position is that?
  5. If there are 12 people in front of you, what position are you in?
  6. Which position is the last carriage in a train with 12 carriages?
Answers:
  1. You are in the fifth position
  2. You are in the 11th position
  3. Platform 6 is the sixth platform
  4. The third carriage is the third from the front
  5. You are in the 13th position
  6. The last carriage is the twelfth carriage

FAQ

What are ordinal numbers?

Ordinal numbers are numbers that show the position or order of things in a line or group. They tell us "first", "second", "third", and so on, instead of just counting how many there are.

Why do we need ordinal numbers?

Ordinal numbers help us understand where we are in a line, queue, or sequence. They're useful for following directions, understanding turns, and solving problems in everyday life.

How can I practice ordinal numbers?

You can practice by counting positions in lines, using ordinal words when describing where you are in a queue, or playing games that involve ordering things from first to last.

What's the difference between ordinal and cardinal numbers?

Cardinal numbers tell us how many there are (one, two, three), while ordinal numbers tell us the position (first, second, third).

Are ordinal numbers used in other countries?

Yes, most countries use ordinal numbers in the same way we do. The words might be different in other languages, but the idea is the same - showing position or order.
