The dinosaur footprint measurement question prompts
Adult prompts and extension questions for measure footprints, estimate stride length and compare dinosaurs.
Quick answer
By measuring dinosaur footprints, you can estimate how big the dinosaur was, how fast it walked, and even compare its stride to other dinosaurs!Learning outcome
By the end of this page, you will be able to measure footprints, estimate stride length, and compare different dinosaur sizes and walking speeds. Success signs:- You can use a ruler or measuring tape to measure the length of a footprint
- You can estimate how far a dinosaur walked between footprints
- You can compare footprints to understand how big different dinosaurs were
- You can explain how footprint size relates to dinosaur size
Why this matters
Dinosaur footprints help scientists learn about the animals that lived millions of years ago. When you measure footprints, you're doing the same kind of science that real palaeontologists do! You can find out how fast a dinosaur walked, how big it was, and even whether it was a baby or a grown-up. This kind of measurement helps you understand the world around you and how maths connects to nature and history.How it works
To measure dinosaur footprints, you need to:- Find a footprint (or draw one on paper)
- Measure the length from the front to the back of the footprint
- Measure the distance between two footprints (this is the stride)
- Compare the measurements to understand the dinosaur's size and speed
Examples you can see
Let's imagine you found a footprint in the sand. It's 15 centimetres long. That's about the size of your hand! If the footprint was made by a baby Triceratops, it might be smaller than a grown-up one. If you find two footprints that are 30 centimetres apart, that's the stride – how far the dinosaur walked between placing its feet. Here's a table showing how footprint size relates to dinosaur size:| Dinosaur Type | Average Footprint Length | Estimated Size |
|---|---|---|
| Compsognathus | 3 cm | Small chicken-sized |
| Velociraptor | 10 cm | Small dog-sized |
| Triceratops | 30 cm | Large rhino-sized |
| Tyrannosaurus Rex | 60 cm | Large car-sized |
Try it as a mini adventure
Adventure: Dinosaur Footprint Detective You are a palaeontologist on a dig site! Your mission is to find and measure footprints to learn about the dinosaurs that lived there. 1st time: You find a footprint that is 20 cm long. What kind of dinosaur might have made it? 2nd time: You find two footprints that are 40 cm apart. What does this tell you about how the dinosaur walked? 3rd time: You find a footprint that is 50 cm long. Is this bigger or smaller than the first one? 4th time: You find a footprint that is 15 cm long. How does this compare to the biggest footprint you found? 5th time: You measure a footprint and find it's 12 cm long. How many of these footprints would fit in a 1 metre ruler? 6th time: You find a footprint that is 30 cm long. What do you think the dinosaur's stride might be?Common mistakes
- Mistake: Measuring the width of the footprint instead of the length.
Why it happens: Children might think the footprint is a rectangle and focus on the width.
Fix: Always measure from the front to the back of the footprint, not side to side. - Mistake: Confusing stride with footprint size.
Why it happens: Children may think the stride is the size of the footprint.
Fix: The stride is the distance between footprints, not the size of the footprint itself. - Mistake: Thinking bigger footprints always mean bigger dinosaurs.
Why it happens: Children might not know that baby dinosaurs have smaller footprints.
Fix: Explain that footprints can show the age of the dinosaur too. - Mistake: Not measuring from the same point on each footprint.
Why it happens: Children might measure from different places on the footprint.
Fix: Always measure from the front of the footprint to the back.
Parent and carer guide
You can help your child by:- Setting up a footprint measuring game in the garden or sandpit
- Using a ruler or measuring tape to measure the footprints
- Discussing how footprints can tell us about dinosaurs
- Asking questions like "How do you think this dinosaur walked?" or "Is this footprint bigger or smaller?"
- Encouraging your child to make their own footprints and measure them
Practice questions
- What is the best way to measure a footprint?
- How do you measure stride?

- Footprints tell us about size, speed, and age of the dinosaur
- It might be a medium-sized dinosaur like a Velociraptor
- Longer strides usually mean faster walking
FAQ
How big were the biggest dinosaurs?
The biggest dinosaurs were over 12 metres long and weighed more than 50 tonnes. Their footprints were often over 60 centimetres long!
Can I find dinosaur footprints in real life?
Yes! Many places around the world have fossil footprints. Some are in museums, and others are in natural parks where you can see them in the ground.
What is stride length?
Stride length is the distance between two footprints. It tells us how far a dinosaur walked between placing its feet.
How can I make my own dinosaur footprint?
Use clay or sand to make footprints. You can use your hands or toys to make different sizes of footprints.
Why do some footprints look different?
Different dinosaurs had different foot shapes. Some had three toes, some had two toes, and some had claws. These differences tell us about their walking style.
