Maths in surfing: match or routine time

Quick answer

Maths in surfing helps you understand match or routine times, like how long a surfing competition lasts or how long you have to complete a surfing routine. You use clocks, time limits, and counting to work out when your turn starts and ends.

Learning outcome

By the end of this page, you will be able to read clocks and understand time limits for surfing routines and matches, so you can tell when your turn starts and ends, and how long you have to do your best surfing.

Success signs:

• You can read the time on a clock to the nearest minute.
• You can tell how long a surfing routine or match lasts.
• You can work out when your turn starts and ends using time.
• You can use time to plan your surfing practice.

Why this matters

Surfing is not just about catching waves – it's also about timing! Whether you're competing in a surfing match or doing your own surfing routine, knowing how to read time and understand time limits is very important. It helps you know when to start, how long you have to surf, and when to finish. This is useful not just in surfing, but also in school, games, and daily life. Time helps you plan, stay on track, and do your best!

How it works

Surfing matches and routines are timed. You can think of time in two ways:

1. Time on the clock: This is the time you see on a clock, like 10:30 or 3:15.
2. Time limits: This is how long something lasts, like 3 minutes or 1 hour.

When you surf, you might have a limited time to do your routine. For example, if your routine is 2 minutes long, you need to know when it starts and ends. You can use a clock to see the time, and you can count the minutes to know how much time you have left.

Examples you can see

Let’s look at some real examples of time in surfing.

Example 1: Surfing Match Times

Imagine a surfing match where each surfer gets 30 seconds to perform their best wave. If the match starts at 10:00, when does the first surfer finish?

Step-by-step:

1. Match starts at 10:00.
2. Each surfer gets 30 seconds.
3. 10:00 + 30 seconds = 10:30.

So, the first surfer finishes at 10:30.

Example 2: Surfing Routine Time

If your surfing routine lasts 4 minutes and starts at 2:15, when does it end?

Step-by-step:

1. Routine starts at 2:15.
2. Routine lasts 4 minutes.
3. 2:15 + 4 minutes = 2:19.

So, your routine ends at 2:19.

Example 3: Time Between Surfers

Each surfer gets 2 minutes to surf. If the first surfer finishes at 11:20, when can the next surfer start?

Step-by-step:

1. First surfer finishes at 11:20.
2. Next surfer starts right after.
3. So, next surfer starts at 11:20.

There is no gap, so the next surfer starts at the same time the first one finishes.

Adventure: Surfing Time Challenge

You are at a surfing competition! Here’s your challenge:

1. Your surfing routine starts at 9:45.
2. Your routine lasts 3 minutes.
3. You have a 5-minute break before your next wave.
4. After your break, you get 2 minutes to catch your next wave.

Question: What time do you finish your surfing routine and your next wave?

Step-by-step:

1. Routine starts at 9:45.
2. Routine lasts 3 minutes → 9:45 + 3 minutes = 9:48.
3. Break starts at 9:48 and lasts 5 minutes → 9:48 + 5 minutes = 9:53.
4. Next wave starts at 9:53 and lasts 2 minutes → 9:53 + 2 minutes = 9:55.

Answer: You finish your surfing routine and next wave at 9:55.

Common mistakes

• Mistake: Thinking that 10:59 + 1 minute = 11:00, but getting confused about the hour.
• Why it happens: Children sometimes forget that when minutes go past 59, they reset to 0 and the hour increases.
• Fix: Use a clock or draw a clock to help you see how minutes change.

• Mistake: Adding time incorrectly, like 10:30 + 40 minutes = 10:70.
• Why it happens: Children might not know that 60 minutes = 1 hour.
• Fix: Break the time into hours and minutes, like 10:30 + 40 minutes = 11:10.

• Mistake: Confusing the start and end times of a routine.
• Why it happens: Children might forget that the routine ends after the time has passed.
• Fix: Use a timeline or draw the clock to show start and end times.

Parent and carer guide

Helping your child with time in surfing is easy and fun!

1. Use a real clock: Set a timer or use a clock to show the time during play or practice.
2. Practice counting: Ask your child to count forward or backward in minutes to help with time.
3. Relate to daily life: Use time for everyday activities like cooking, reading, or walking to school.
4. Be patient: Time can be tricky, so don’t rush. Let your child make mistakes and learn from them.
5. Encourage creativity: Let your child make up their own surfing routines and time them!

Remember, learning time is about building confidence. Keep it playful and keep practicing!

Can I use a stopwatch for surfing?

Yes! A stopwatch can help you time your routines or even practice catching waves. It’s a fun way to learn about time.

Why is time important in surfing?

Time helps surfers know when to start and finish their routines, how long they have to catch a wave, and how to plan their surfing session.

What if I get confused with minutes and hours?

It’s okay to get confused! Practice with a clock or draw a timeline. You can also break time into smaller parts, like 10 minutes at a time.
