The Big Countdown Collection - 6 Books

Question: do you know how many different insects there are in the rainforest? Answer: 30 million. How about the number of grains of sand on Earth? Well, that's 7 quintillion and 500 quadrillion (obviously...)

The six books in this collection will help children count down the world with an amazing mix of numbers, facts and stats - ranging from the highest to the lowest.

Using infographics and photographs, the books will help children visualise and understand numbers and build their skills in data handling. They cover a range of topics including science, nature, biology and the solar system.
