## 50 Amazing things kids need to know about mathematics

### Anne Rooney

*We don't normally review childrens' books on Plus, but when this colourful volume landed on our desk we couldn't resist. It appeared to do exactly what we try to do all the time: reveal the beauty and fun side of maths and show how it comes up everywhere, as a natural language in which to talk about the world. So we passed it on to two expert representatives of the book's target audience, which is 7 to 11-year olds. Here is what Thomas (12) and Amelia (10) Beauchamp of Walkley, Sheffield thought about the book.*

We think that *50 Amazing things kids need to know about mathematics* is a very good book because it puts into context how maths is used in everyday life such as how to create a code and how to lose a day. Each section consists of two to four pages explaining the history or background of the mathematical idea, a *see for yourself* section which gives you experiments to try — for example how quickly you can work out the sum of the numbers from 1 to 700, or writing your age in binary, base 6 or base 8 — as well as interesting facts or philosophical questions — for example if the number of pirates has decreased as global temperatures have risen, does this mean that the rise in global temperature has killed pirates or the lack of pirates causes global warming? Or neither of these?
The contents and index makes information easy to find and it is a really good book to dip into and find a fascinating fact.

It is a very good book and one we would recommend to anyone who was interested.
