Users may have noticed that site has not been updated for some time! Apologies for this, but we are working on a new website project with the help of a web designer. Details should be published here when this site becomes available. In the mean time please continue to use any of the resources you can find here!

Thanks - Thinkmathematics

Our Mission
- thinkmathematics.com is designed for teachers of mathematics around the English speaking (for the moment)world. As experienced teachers of mathematics we recognise the need to constantly review, inform and improve our practice. As such it has become our mission to develop rich ideas, activities and resources designed to promote mathematical thinking and engagement. The contents of this website are the fruits of this process. We would not pretend or aspire to a comprehensive collection preferring to concentrate on the quality rather than the quantity of resources. Each resource can be used exactly as it is or taken, bent and twisted to suit the needs of the teachers and students in question. We hope you find useful activities and we welcome your feedback jnoble@thinkmathematics.com
