Everymind's Pre-Euclid - Harris

This is an introduction to the ideas of Euclid Book I, suitable for anyone of any age who wishes to cure an ignorance of Euclid. All you need are a ruler, compass, protractor, and an imagination. There are 317 problems and, while the focus is on Book I, in-roads are made on Books II, III, IV, VI, and XI. The book is suitable for use in schools, as, going on to Euclid from here, all the fundamental ideas would be in the students' minds, ready to be made rigorous.
