Welcome and Review
- Ask students for any final questions before passing out the quiz.
Quiz
Debugging Activity
- Explain to students that you will now be exploring how to read analyze and respond to errors in code.
  - Present students with a longer piece of code that will produce an error (e.g. code). Ask them to read through it and predict what will be printed out.
  - Remind students that when reading through code we go line by line, as if we are the interpreter.
  - Run the code, display the stack trace, and have students analyze the error message reported.
  - Explain that, much like in Snap, debugging is the process of tracking and fixing errors in your code.
- Indentation Errors:
  - Errors the students are most likely to have seen
    - "IndentationError: unindent does not match any outer indentation level"
  - Ask student why these errors are caused and how they find/fix this type of error? Suggest using the tab key to indent and the shift-tab to remove an indent as ways to avoid the error.
  - Present an additional tool by running: python3 -m tabnanny input.py where input.py is the python source file having the unident error. The output will help you find the error.
- Direct students to work through and complete this web tutorial on debugging

Make sure to provide extended time on the quiz for any students that have that requirement in an IEP or 504 plan.
