Instructions
On each homework assignment, please write (i) your name, (ii) name of course, and (iii) homework number. You are allowed and encouraged to work together on homework. Yet, each student is expected to turn in their own work. In general, late homework will not be accepted. However, you are allowed to turn in up to three late homework assignments with no questions asked. When doing your homework, I encourage you to consult the Elements of Style for Proofs.
The following framework assumes that we will be in a remote setting. If we happen to return to face-to-face classes, we will adjust in a natural way. With a few exceptions, homework assignment will consist of two parts.
Part 1: Prior to the start of class, you will need to capture your handwritten work digitally and then upload a PDF to BbLearn. There are many free smartphone apps for doing this. I use TurboScan on my iPhone. Submitting your work prior to class allows me to see what you accomplished outside of class.
Part 2: During class, we will discuss most of the problems that are due that day. While we are discussing them, you should either annotate your work and/or take notes on separate paper. It’s expected that most of the work you did prior to class will need to be refined. It is your responsibility to process this in some way. Annotating your work or taking notes will increase the chances that you are processing the work in a meaningful way. If you choose to annotate your work, please use a different color than what you originally used to complete your assignment. After class, you will need to capture your annotations/notes digitally and then upload a PDF to BbLearn.
Assignments
Unless otherwise indicated, submit each of the following assignments via BbLearn. I reserve the right to modify the assignment if the need arises. These exercises will form the basis of the student-led presentations.
