• carry out at least  80% of the "Participation Activities" (the orange ones) in each section of the reading
• complete the following "Challenge Activities"—for every challenge activity you cannot pass at least one test for, please take a screen shot of your final attempt after 20 minutes and submit that here (make sure your photo includes the challenge number)
  
  • Challenge 6.1.2: Basic function call
  • Challenge 6.2.2: Function call in expression
  • Challenge 6.4.1: Function with branch: Popcorn
  • Challenge 6.5.1: Unit testing
• post one or more questions to the class Piazza board with the "gi 14" tag (if there's already a post for a question you had, there's not need to add another one; feel free to post anonymously)
