The sailing treasure island quest

Use charts, wind direction, distances and tide times with adult safety framing.

Quick answer

The sailing treasure island quest uses real-world maths to help you navigate, plan your journey, and find treasure by reading charts, understanding wind directions, calculating distances, and checking tide times.

Learning outcome

By the end of this page, you will be able to use charts, wind direction, distances, and tide times to plan a safe sailing journey to find treasure. Success signs:
  • You can read a sailing chart to find your starting point and treasure location
  • You can follow wind direction arrows to plan your sailing route
  • You can measure distances between points on a map
  • You can check tide times to plan when to sail

Why this matters

Maths is used every day when people sail, whether they're going to a beach, crossing a lake, or exploring islands. When you sail, you need to know:
  • How far you have to go (distance)
  • Which way the wind is blowing (wind direction)
  • When the water is high or low (tide times)
  • How to read a map (charts)
These skills help you sail safely and find your way to treasure or anywhere else you want to go. Whether you're planning a family boat trip, playing a sailing game, or building a boat in your garden, maths helps you make smart decisions.

How it works

Let's imagine you're going on a sailing treasure island quest. Here's how to use maths to plan your journey:
  1. Look at a sailing chart to find where you start and where the treasure is
  2. Check the wind direction to know which way to sail
  3. Measure how far you have to go using the chart's scale
  4. Check tide times to know when the water is deep enough to sail

Examples you can see

Let's say you're on a treasure island quest and you're starting at a point marked "A" on the chart. The treasure is at point "B". Here's how to plan your journey: Step 1: Read the chart Look at the chart. You see point A and point B. The chart shows you that A is at 50°N and 20°E, and B is at 50°N and 25°E. That means you're sailing east. Step 2: Check wind direction The chart shows wind direction arrows. The wind is coming from the north-west, so you need to sail towards the south-east to catch the wind. Step 3: Measure distance The chart has a scale. Every 1 cm on the chart equals 1 km in real life. You measure the distance between A and B, and it's 5 cm. So, you're sailing 5 km. Step 4: Check tide times The chart has tide times. You need to sail when the tide is high, so you know the water is deep enough. You check the tide times and find that the tide is high at 10:00 am.

Try it as a mini adventure

Adventure: The Sailing Treasure Island Quest You're going on a sailing treasure island quest. Here's your challenge:
  1. Start at point A on the chart
  2. Follow the wind direction arrows to find your route
  3. Measure the distance between A and B
  4. Check the tide times to find the best time to sail
  5. Write down your plan
4th time: Measure distance You measure the distance between A and B on the chart. It's 3 cm. If 1 cm = 1 km, how far are you sailing? 5th time: Check tide times The tide is high at 9:00 am. If you start at 8:30 am, can you sail? Why or why not? 6th time: Plan your journey Write down your sailing plan:
  • Start at point A
  • Sail towards point B
  • Use the wind direction
  • Sail at 9:00 am

Common mistakes

  • Mistake: Thinking you can sail in any direction
    Why it happens: Not reading the wind direction arrows
    Fix: Always check the wind direction and sail with the wind
  • Mistake: Measuring distance wrong on the chart
    Why it happens: Not using the chart's scale
    Fix: Always use the scale shown on the chart
  • Mistake: Sailing when the tide is low
    Why it happens: Not checking tide times
    Fix: Always check tide times before sailing

Parent and carer guide

As a parent or carer, you can help your child by:
  • Using a real sailing chart at home or in a book
  • Practising measuring distances using a ruler and scale
  • Discussing wind direction using a compass or wind sock
  • Looking at tide times online or in a sailing book
  • Creating a simple treasure island map with your child
You can also play a game where you pretend to sail and plan a journey using maths. Ask questions like:
  • How far do we have to go?
  • Which way is the wind blowing?
  • When is the best time to sail?
Remember to keep the activity fun and exploratory. Don't worry if your child makes mistakes – they're part of learning!

Practice questions

  1. On a sailing chart, 1 cm equals 2 km. You measure 3 cm between two points. How far apart are they?
  2. If the wind is coming from the south, which way should you sail to catch the wind?
  3. What tide time is best for sailing?
  4. Why is it important to check tide times before sailing?
  5. How can you use a chart to find your way?
Answers:
  1. 6 km (3 cm × 2 km)
  2. Towards the north
  3. When the tide is high
  4. To make sure the water is deep enough for your boat
  5. Charts show points, distances, and directions to help you navigate

FAQ

What is a sailing chart?

A sailing chart is a map that shows water, land, and important sailing information like wind direction, tide times, and depth of water.

Why do I need to know wind direction?

Wind direction helps you know which way to sail. You sail with the wind to go faster and easier.

How do I measure distance on a chart?

You use a ruler and the chart's scale. The scale tells you how many real-world units (like km) equal 1 unit on the chart (like 1 cm).

What if I don't have a chart?

You can make a simple map or use a compass to find directions. But a chart is the best way to plan a safe sailing journey.

Can I use this maths for other things?

Yes! The same maths helps you plan trips, play games, and even build things. Maths is used everywhere.
