Welcome to piLEARN, an educational resource with a focus on mathematics. My name is Martin Hansen and I've taught at Shrewsbury School since 1988. The school is boarding, coeducational, with 700 pupils. The purpose of this website is to make available to students and parents the tried and tested teaching resources that I've developed during my twenty-six years at the school. They continue to evolve; fresh material is added frequently, usually immediately after being used with students. I also like the idea of giving something back to mathematics; all who pass through are welcome to take away whatever they find useful and interesting.
The teaching materials presented through piLEARN have been prepared with the idea of a paperless school in mind. The PDF-downloads are designed to be annotated on screen as the reader progresses through the chapters. To do this as a highly motivated and organised adult, an iPad is ideal. I hesitate to claim that affordable computing technology has yet reached the stage where this is a practical proposition for classroom learning with pupils. That time will come.
The illustration above is of the main teaching block at Shrewsbury. It's an iPhone photo I took and passed through various RISC OS software packages on a Raspberry Pi computer. All who have done maths at Shrewsbury School will have sat in the classrooms in this building.
