Maths hiding in garden: sunlight hours

Record sunny and shady times in different places.

Quick answer

Maths hiding in garden: sunlight hours helps us understand how long different parts of our garden get sunshine, which helps us plan where to plant flowers, vegetables, or play.

Learning outcome

By the end of this page, you will be able to measure and record how many hours different parts of your garden get sunlight. Success signs:
  • You can use a clock or timer to check how long a spot in your garden is sunny
  • You can draw a simple chart to show which parts of your garden get the most sun
  • You can explain why some areas of your garden are sunnier than others
  • You can use maths to decide where to put your plants

Why this matters

Understanding how much sunlight different parts of your garden get is important for growing healthy plants. Some plants need lots of sun, while others prefer shade. When you know which areas get sunlight and which don’t, you can:
  • Plant sun-loving flowers like sunflowers in the sunny spots
  • Grow shade-loving plants like ferns in the shady corners
  • Plan where to put your garden bench or play area
  • Learn about time, measurement, and data in a fun, real-world way

How it works

To find out how many hours your garden gets sunlight, follow these steps:
  1. Choose a sunny day with clear skies
  2. Mark different spots in your garden with small flags or stones
  3. Use a clock or timer to check how long each spot is in the sun
  4. Record your results in a chart or table
  5. Compare the data to see which spots get the most sunlight

Examples you can see

Let’s imagine you are a gardener measuring sunlight in your garden. You have three spots: the big sunny patch, the shady corner, and the area under the big tree. Spot A – Big sunny patch
  • Start time: 8:00 am
  • End time: 6:00 pm
  • Sunlight hours: 10 hours
Spot B – Shady corner
  • Start time: 10:00 am
  • End time: 2:00 pm
  • Sunlight hours: 4 hours
Spot C – Under the big tree
  • Start time: 11:00 am
  • End time: 1:00 pm
  • Sunlight hours: 2 hours
You can draw a simple bar chart to show this data: How many hours each spot gets sunlight

Try it as a mini adventure

Adventure: The Sun-Spot Survey You are a garden detective on a mission to find the perfect spot for a new flower bed. You need to check how many hours each part of your garden gets sunlight. Step 1: Choose a sunny day and gather your tools: a notebook, a pencil, and a clock or phone. Step 2: Pick 4 different spots in your garden and mark them with small stones or flags. Step 3: At 8:00 am, check if each spot is sunny or shady. Step 4: At 12:00 pm, check again. Step 5: At 4:00 pm, check again. Step 6: At 6:00 pm, check one final time. Step 7: Record your findings. For each spot, write down how many hours it was sunny. Step 8: Draw a simple chart to show your results. Step 9: Decide which spot is best for sun-loving plants and which is best for shade-loving plants. Step 10: Explain your findings to a grown-up.

Common mistakes

  • Mistake: Not checking the time carefully
    Why it happens: Children may rush or get distracted by playing.
    Fix: Use a timer or set a reminder on your phone to check the time regularly.
  • Mistake: Confusing morning and afternoon sun
    Why it happens: Some children mix up the times of day.
    Fix: Use a clock and write down the exact time each check happens.
  • Mistake: Forgetting to record data
    Why it happens: It’s easy to forget to write things down.
    Fix: Make a checklist to help you remember to record each spot.
  • Mistake: Thinking all spots get the same amount of sun
    Why it happens: Some children don’t notice how the sun moves or how shade changes.
    Fix: Check several times during the day to see how sun and shade change.

Parent and carer guide

As a parent or carer, you can help your child learn about sunlight hours by:
  • Choosing a sunny day and going outside together
  • Using a simple clock or phone to check times
  • Encouraging your child to draw a chart or table of their results
  • Discussing why some spots get more sun than others (e.g. trees, buildings, hills)
  • Using the data to help plan where to plant flowers or vegetables
  • Practising counting and time-telling skills in a fun, practical way
What to say:
  • “Let’s see how many hours each part of the garden gets sun.”
  • “Can you count how many times you checked each spot?”
  • “Which spot do you think is best for sun-loving plants?”
  • “How can we use this data to plan our garden?”
What not to worry about:
  • It’s okay if your child makes small mistakes in timing
  • They don’t need to be perfect at counting hours
  • It’s more important to enjoy the learning process than to get exact numbers
