Practice Materials

Parsons Problems

These problems present the complete code for a program, but in a mixed-up order. Your task is to arrange the pieces correctly to "write" the described program. These problems are a great first step in learning because they allow you to focus on the semantics of programming rather than the syntax.

• 4.12. Mixed-up Code Questions
  • Problem 1
  • Problem 2
  • Problem 3
  • Problem 4

"Solutions" for these four programs are included in the Code Walkthrough section below.

You are welcome to complete additional problems from this section.

Debugging Problems

Fixing programs that are "almost" correct but not yet functional is a crucial skill. As teachers, we often assume students will develop this skill by debugging their own work. However, it can be beneficial to provide explicit practice in debugging. The following problem is designed to give you semi-guided practice in debugging.

1. Bad code for Odd/Even produced by an AI.

The solution for this program is included in the Code Walkthrough section below.

(Paired) Practice Programs

Each week, I will provide you with several practice programs (non-graded) that I encourage you to attempt, with your partner, before tackling the graded assignments.

• Conditionals Paired Programing Activity

Additional Textbook Activities

These are great for some additional practice. You should complete these on your own rather than with a partner.

• 4.12. Mixed-up Code Questions
  • Remember that you can change them from Parsons Problems to Active Write Code.
