Sailing maths quest: time

Quick answer

When you sail, you need to plan your journey using time, maps, and bearings. You can read clocks, work out how long trips take, and use time to plan your sailing adventure.

Learning outcome

By the end of this page, you will be able to read digital and analogue clocks, work out how long journeys take, and use time to plan a sailing adventure.

• You can tell the time to the nearest minute
• You can add and subtract time to plan sailing trips
• You can use time to work out when to start and finish a sailing race
• You can understand how time helps in sailing with maps and bearings

Why this matters

Time is super important when you're sailing! You need to know exactly when to start your journey, how long it will take, and when to finish. If you're racing in a sailing competition, you need to be precise with time to win. In real life, time helps you plan your day, get to school on time, and know when your favourite TV show is on. When you sail, time helps you avoid getting lost and makes sure you arrive safely.

How it works

When you sail, you need to use time in different ways:

1. Read the time on a clock
2. Work out how long a trip will take
3. Plan when to start and finish your journey
4. Use time to follow a sailing map and navigate

Let's imagine you're on a sailing quest. You need to sail from your harbour to a treasure island. First, you look at the clock to see what time it is. Then you plan how long the journey will take. You use time to make sure you start at the right time and arrive at the right time.

Examples you can see

Let's go on a sailing adventure together!

Example 1: Reading the clock

You wake up at 7:30 am to start your sailing trip. What does the clock show?

• The hour hand points to 7
• The minute hand points to 6
• 6 is 30 minutes
• So it's 7:30

Example 2: Planning a trip

You start sailing at 9:15 am. Your journey takes 2 hours and 30 minutes. What time will you arrive?

1. Start time: 9:15 am
2. Add 2 hours: 11:15 am
3. Add 30 minutes: 11:45 am
4. You arrive at 11:45 am

Example 3: Countdown timer

You're racing in a sailing competition. You have 45 minutes to sail to the finish line. You start at 2:00 pm. When does the race end?

1. Start time: 2:00 pm
2. Add 45 minutes: 2:45 pm
3. The race ends at 2:45 pm

Try it as a mini adventure

Sailing Maths Quest: The Treasure Island Adventure

You are a young sailor on a quest to find treasure! Here's your mission:

1st time: You wake up at 6:45 am to prepare your boat.

2nd time: You start sailing at 7:20 am.

3rd time: You sail for 1 hour and 45 minutes.

4th time: You arrive at the treasure island.

5th time: You find treasure at 9:50 am.

Challenge: What time did you arrive at the treasure island?

1. Start time: 7:20 am
2. Add 1 hour: 8:20 am
3. Add 45 minutes: 9:05 am
4. You arrive at 9:05 am

Great job! You found the treasure in time.

Common mistakes

• Mistake: Thinking 60 minutes = 1 hour, but confusing it with 60 seconds = 1 minute.
• Why it happens: Children mix up minutes and seconds.
• Fix: Use a clock with a second hand to show how 60 seconds make 1 minute.
• Mistake: Adding time like 3:45 + 2:30 = 5:75.
• Why it happens: Children add minutes and hours separately without carrying.
• Fix: Add minutes first (45 + 30 = 75), then convert 75 minutes to 1 hour 15 minutes.
• Mistake: Not using a.m. and p.m. correctly.
• Why it happens: Children don't understand the 12-hour clock system.
• Fix: Practice with a 12-hour clock and use words like "morning" and "evening".
