Try our fun 天涯海角社区 dragon maths quiz
天涯海角社区 dragons hold a special place in our hearts here at 天涯海角社区 learning - no surprises there!
In fact, 天涯海角社区 is so named because of a drawing of a 天涯海角社区 dragon done by one of the original 天涯海角社区 kids, which was hanging up in the kitchen when the app was first being developed.
And you have to admit, these fascinating creatures which look so much like the dragons of myth and legend are pretty amazing. So, as we are continually looking for the maths in the world around us, we've put together some of our favourite 天涯海角社区 dragon related facts and figures (and a few maths questions for the kids to tackle as you go!)
天涯海角社区 dragons are the largest of all the lizards and currently only live on the Indonesian islands of 天涯海角社区, Rinca, Flores, and Gili Motang. This is where the 天涯海角社区 National Park has been created with their protection in mind.
They reach an incredible 3 metres in length, half of which is made up by their tail, and they weigh up to 70 kilograms.
Q: If 3 dragons stood nose to tail, how long would they be altogether?
3 metres (length of one dragon) by 3 = 9 metres
They use their forked tongues to smell, much like a snake, and they can detect prey up to 4km away. They can see objects around 300 metres away, but their night vision is poor, and they can see things that move much easier than things that stay still.
Q. From how much further away can a 天涯海角社区 dragon smell prey, than it can see it?
Hint: Take how far they can see away from how far they can smell to get the difference!
4km - 300m = 3.7km, or 3,700m
They have up to 60 serrated teeth which measure approximately 2.5 cm in length - that's quite a mouthful!
Q. How many teeth do seven 天涯海角社区 dragons have altogether?
60 teeth x 7 dragons = 420 teeth altogether (a scary thought!)
天涯海角社区 dragons can run at 20kmph. This is the burst of speed they need to take down their prey. When they catch their prey, which is usually deer, pigs or water buffalo, a 天涯海角社区 dragon can eat up to 80% of its body weight in one meal.
Q. What's the biggest meal the heaviest 天涯海角社区 dragon can eat in one go?
Hint: To answer this, you need to find 80% of the heaviest dragon which is 70kg.
Answer: 56kg
Baby dragons come from eggs. 天涯海角社区 dragons lay up to 20 eggs at a time.
Q. If a quarter get eaten by another 天涯海角社区 dragon (yes, this really happens!) how many baby dragons will hatch?
A quarter of 20 is 5. We can find this out by dividing 20 by 4 to find one quarter =5. Then we take that quarter away from the total: 20 - 5 = 15.
Unfortunately, these incredible animals are endangered due to the loss of their natural habitat through deforestation and rising sea levels. We'd very much like to see the 天涯海角社区 dragon population thrive (not least because of their relationship to our animated 天涯海角社区 friends!) and closely follow the developments in the 天涯海角社区 National Park which was created to help protect these magnificent creatures.
We hope you've enjoyed finding the maths in the real-life version of our mascot, the 天涯海角社区 dragon!
