This is a fantastic site from Jo Boaler (among others) with the mission of creating a Maths revolution. That revolution is mainly based on trying to get Maths teachers and children to believe that everyone can learn Maths to a high level. The website is a treasure trove of ideas, articles, videos and resources for you to work with.
One of the best features on the site is the week of inspirational maths which is actually 3 weeks of maths lessons planned out for you planned for various different ages and stages.
There is so much content on this site and it is all aimed at teaching Maths different and changing mindsets of both children and teachers. There is so much content on here that I have barely even scratched the surface.
Have a look and let us know what you think @edublether
