Screencasts for Use with this Book

Dr. Robert Talbert, a colleague of mine at Grand Valley State University, has developed a collection of over 100 screencasts for use with this textbook. These screencasts are an excellent supplement for students to use, especially for those instructors teaching their course with an inverted or flipped classroom model.  Click here to access these screencasts.

Version 1.1
There are no changes in content between Version 2.0 and Version 1.1.  The only change is that the appendix now contains solutions and hints for more exericses.  In addition, the study guides for the book have been revised to contain a list of exercises to complete.  All exercises in these lists have solutions or hints in the appendix.

Version 1.1 of the book is still available.  Click here to download Version 1.1 or click here to purchase it at Amazon.com.


Introduction to Mathematical Proofs Blog

I have just started a blog dealing with the introduction to proofs course.  With this blog, I plan to share my thoughts about introduction to proofs courses, information abut the book Mathematical Reasoning: Writing and Proof, and information about other free resources for this course including other free textbooks.
