# How to Teach Kids About Telling Time With a Sundial > Discover how a simple homemade sundial can help children truly understand time — with hands-on activities for ages 3–12 that connect maths, science, and everyday life. Source: https://holidayeducationist.com/en/blogs/how-to-teach-kids-about-telling-time-with-a-sundial --- Sundials might feel like ancient history, but they are one of the most powerful hands-on tools you can use to help children *truly understand* how time works. Before clocks, before smartphones, humans looked at shadows — and that simple idea can unlock something magical for young learners. This post walks you through how to use a sundial (real or homemade) as a springboard for teaching children about time, the sun, and the world around them. --- ## Why Sundials Make Time Concepts Click for Kids ![child pointing at sundial garden](https://hebe.b-cdn.net/pexels_photo_8297526_b084e6d1b7.jpg) Most children learn to tell the time by memorising clock positions — which is useful, but it can feel abstract. They learn *where* the hands go without really understanding *why* time moves forward or what it represents. A sundial changes that completely. When a child watches a shadow move across a dial over the course of a morning, they are experiencing time rather than just reading it. This kind of embodied, sensory learning sticks far better than rote memorisation. ### Time as a Physical Thing Young children are concrete thinkers. They understand things they can see, touch, and observe. A sundial makes the passage of time visible in real time — the shadow literally moves as they watch. That slow, steady drift from one mark to the next gives children a felt sense of duration that a digital clock simply cannot provide. ### Connecting Maths, Science, and Everyday Life Sundials sit beautifully at the intersection of early science (the sun's movement, shadows, light) and early maths (numbers, sequencing, estimation). If you are looking for ways to connect these subjects naturally, a sundial lesson is one of the best cross-curricular activities you can do outdoors. --- ## What Age Is Right for Sundial Learning? ![young children outdoor science activity](https://hebe.b-cdn.net/pexels_photo_12719277_5df5773aa0.jpg) The good news is that sundial activities can be adapted for a wide age range. - **Ages 3–5:** Focus purely on the wonder. Watch the shadow move. Talk about "morning sun" and "afternoon sun." Use simple language like *"the shadow is pointing here now — where will it point after lunch?"* - **Ages 5–7:** Introduce the numbers on the dial. Connect the sundial reading to an analogue clock. Ask the child to predict where the shadow will be in one hour. - **Ages 7–10:** Go deeper. Discuss *why* the shadow moves. Introduce compass directions (the gnomon — the upright part — typically points north in the northern hemisphere). Talk about time zones at a very basic level. - **Ages 10–12:** Challenge them to build a more accurate sundial, research the equation of time, or compare sundial readings with clock time across different seasons. The key is to meet children where they are and let curiosity lead. --- ## How to Make a Simple Sundial at Home or in Class ![child making paper sundial craft](https://hebe.b-cdn.net/pexels_photo_36692184_4adf566a3e.jpg) You do not need to buy anything special. A homemade sundial is a brilliant craft-meets-science project that takes about 20–30 minutes and costs almost nothing. ### What You Need - A paper plate or piece of thick card - A pencil or a straight stick (this becomes the gnomon) - A ruler and marker - Access to a sunny outdoor space - A clock or watch for reference ### Step-by-Step Instructions 1. **Push the pencil through the centre** of the paper plate so it stands upright. 2. **Take it outside** on a sunny day and place it on a flat surface. 3. **Every hour on the hour**, mark where the shadow falls and write the corresponding time (e.g., 9, 10, 11). 4. **Do this across several hours** — ideally from mid-morning to mid-afternoon. 5. **Once you have four or more marks**, your child has a working sundial they made themselves. The act of returning every hour to mark the shadow is itself a wonderful lesson in patience, observation, and the rhythm of the day. ### Tips for Success - Choose a day with consistent sunshine — partly cloudy days make it tricky. - Make sure the plate does not move between readings (tape it down or mark its position with chalk). - Let the child write the numbers themselves — it reinforces numeral recognition and fine motor skills. --- ## Linking the Sundial to Clock Reading ![parent child comparing clock sundial](https://hebe.b-cdn.net/pexels_photo_38368165_700cc23876.jpg) Once your child has built or observed a sundial, you have a perfect bridge to reading analogue and digital clocks. ### From Shadow to Clock Face Hold an analogue clock next to the sundial and show your child that both are doing the same job — measuring how far the day has moved. The shadow on the sundial and the hands on the clock are both telling the same story. This connection is especially powerful for children who find clock faces confusing. Suddenly the clock is not a mysterious object with arbitrary rules — it is a mechanical version of something they have already understood outside. If your child is working on analogue clock skills, our post on [How to Teach Kids to Read Analogue Clocks With Ease](/en/blogs/how-to-teach-kids-to-read-analogue-clocks) pairs really well with this activity. ### Practise Estimating Time Ask questions like: - "The shadow is halfway between 10 and 11 — what time do you think it is?" - "It was 9 o'clock when we had breakfast. How many shadows ago was that?" - "Where will the shadow be when it is time for dinner?" Estimation is a key early maths skill, and sundials make it feel like a game rather than a worksheet. ### Extend to Seasons If you keep the sundial in the same spot across different seasons, children will notice that the shadow's length and angle change. Summer shadows are shorter at midday; winter shadows are longer. This opens up wonderful conversations about the Earth's tilt and why seasons happen — a topic explored further in our post on [How to Teach Kids About the Seasons (Fun & Easy Ways)](/en/blogs/how-to-teach-kids-about-the-seasons). --- ## Outdoor Games and Activities to Reinforce the Learning ![kids playing shadow games outdoors](https://hebe.b-cdn.net/pexels_photo_5275457_abe0328558.jpg) Once children are familiar with the sundial concept, take the learning further with these playful extensions. ### Human Sundial This is a class favourite and works brilliantly in a school playground or garden. - Use chalk to draw a large circle on the ground. - Mark the hours around the edge. - One child stands in the centre as the "gnomon." - Ask: *"Where is your shadow pointing? What time does that match?"* Children love being part of the instrument — it is memorable, active, and genuinely accurate on a sunny day. ### Shadow Tracing At different times of day, trace a child's shadow on the ground with chalk. Return to the same spot later and compare. Ask: *"Is your shadow longer or shorter now? Why do you think that is?"* ### Time Prediction Challenge Before going back inside, ask children to predict where the shadow will be when they come back out after lunch. Check together and celebrate how close they got. This builds scientific thinking — forming a hypothesis and testing it — in the most natural way possible. --- ## Practical Takeaways for Parents and Educators ![teacher outdoor lesson sunny day](https://hebe.b-cdn.net/pexels_photo_8922635_549b782718.jpg) Here is a quick summary of the most useful ideas from this post: - **Start with observation, not instruction.** Let children watch the shadow move before you explain anything. Curiosity comes first. - **Make the sundial together.** The craft process is part of the learning — do not skip it in favour of a ready-made version. - **Return throughout the day.** Multiple check-ins reinforce the concept of duration and help children feel time passing. - **Connect it to a clock.** Always bridge the sundial experience back to the clock face so the learning transfers to everyday life. - **Ask open questions.** *"What do you notice? What do you wonder? What do you think will happen?"* These questions build scientific and mathematical thinking. - **Revisit across seasons.** A sundial is not a one-day activity — it rewards children who return to it over months. - **Keep it low-pressure.** If it is cloudy, try again another day. The best outdoor learning is flexible and joyful. For families building broader time-telling skills at home, the [123 for Kids](/en/apps/123-for-kids) app is a gentle way to reinforce number recognition alongside these practical activities — helpful for younger children who are still cementing their number knowledge before tackling clock reading. --- Time is one of the most abstract concepts young children have to grasp, and yet the sun has been showing us how it works for thousands of years. A simple sundial — even a paper plate in the garden — can give your child a tangible, memorable foundation that makes every clock they ever read a little easier to understand.
