I've renamed this thread to just "Mathematics Resources" and stripped off the subtitle of "How to lie with statistics" so we can use it for other things...
At school, mathematics is mostly about arithmetic and algebra: adding fractions, solving equations and calculating percentages. These topics are important to understand the formal language that underlies mathematics, but they can appear very dry and boring, with few applications in real life.
But mathematics is so much more, and everybody should understand concepts like prime numbers, graph theory or differential equations. They are of fundamental importance in technology and for understanding of the universe we live in, and they are incredible exciting and beautiful. Mathematics is an essential part of our culture, just like Mozart and Shakespeare.
Mathigon is a collection of educational resources for children, the general public and teachers. These range from interactive eBooks to slideshows, videos, animations and lesson plans. With colourful design and using many new technologies, Mathigon shows how exciting and entertaining mathematics can be.
