Some Truth, Some Validity, Some Opinion: Lessons from an Old Mathematics Teacher to New Mathematics Teachers

By: David A. Crothamel

David A. Crothamel has taught mathematics for thirty-eight years from the seventh grade level up to calculus. Throughout his many years of teaching, he has seen many times teachers skip over proof of the techniques. Students then tend to memorize how to get an answer without knowing the methodology behind it. Crothamel would like this book to be used as a guide for students to navigate the “whys” of some of the mathematics they study.
