How can I help the student already studying high school geometry?
Perhaps your student is already studying geometry in high school and is having problems. Of course you cannot change how he/she was taught in the past. Since this is such a common problem, many publishers have come out with textbooks that emphasize “informal” geometry and geometry concepts, instead of proofs. You could use one of those books, and simply forget about the proving. Yet other books include proofs, but not in the same quantity or same emphasis as in previous years. These include for example Harold Jacobs Geometry: Seeing, Doing, Understanding. The link goes to my review of this book. And even with good preparation, high school geometry and the proofs can still be difficult. All in all, there is no quick and easy answer to the difficulties in this course. Remember that even math teachers in schools struggle with this problem of getting students to understand and construct proofs. Maybe the explanations on Ask Dr. Math: FAQ About Proofs can be of some help.
