Project Inspiration
Why do a project? The idea of a Mathematical project or investigation is something that always really excites a lot of Maths teachers, but often Maths Studies students need a little bit more persuasion to get excited. There are a number of things that can be done to in this attempt to persuade. Some are inspiring and others simply pragmatic but all are worth sharing in the hope that some will do...

Hi there, the link to the Exponential Growth video no longer seems to work. Do you have a title we could search for or an alternative link please. Thanks, Malcolm

Hello, The transfer time in New York is 1h30 and in Papeete 1hr (from the exam style questions). Should this say LA instead of Papeete?
