I start student teaching in August. I will be teaching High School Geometry. Given that it has been 9 years since I took geometry does anyone have a suggestion for a good textbook that I could use to refresh?
I don't think high school geometry can be permanently forgotten, especially if you majored in maths.
I have this book at home and it is wonderful, although in french: Livre Mathematiques mise a niveau - J. Lapointe, M. Sainte-Marie - - Librairie Eyrolles
I definitely know more geometry in general than the high school level students. But my issue is that college level geometry was extremely different from what I remember in high school. It has been almost 10 years or so since I took high school geometry. That is why I am trying to find a book.
Go to the syllabus documents and review what material the students have to learn. Then go to a library and find books that cover that meterial.
