Looking for a meaningful project to go with the Code.org AP CSP Algorithms unit? If you have noticed that Code.org does not really include a full project for this unit, this resource fills that gap with a structured, student-friendly assignment that helps learners apply algorithmic thinking in a clear and practical way.

This resource gives students the chance to do more than just answer lesson questions. They first analyze two different algorithms for the same task, decide which one is more efficient, and explain why. Then they move into a second task where they design their own real-life algorithm in pseudocode using sequence, selection, and iteration.

It works especially well as:

• a unit project
• a performance task-style practice activity
• an assessment for the algorithms unit
• an extension after Code.org lessons
• a review activity for AP CSP algorithm concepts

What students do:

In Part 1, students complete an Algorithm Showdown Worksheet. They compare two algorithms for finding a book in a library and explain which algorithm is better for the situation. This helps students think about efficiency, tradeoffs, and how the structure of a problem affects which algorithm should be used.

In Part 2, students complete a Real-Life Algorithm Design Worksheet. They choose one of three everyday scenarios and write their own pseudocode algorithm. The scenarios require students to apply algorithmic thinking to planning, sorting, or decision-making rather than simply copying a search pattern.

What is included:

• Part 1 student worksheet
• Part 1 teacher answer key
• Part 2 student worksheet
• Part 2 teacher answer key with sample pseudocode
• 10-point rubric with 4 performance levels

What to like about this resource:

The Code.org Algorithms unit teaches important concepts, but many teachers want a more complete culminating activity for students to show what they understand. This project gives you that extra piece. It brings together:

• algorithm analysis
• efficiency
• pseudocode
• sequence, selection, and iteration
• real-world application

Instead of giving students another basic worksheet, this resource asks them to think, explain, and create.

Why it works for students:

Students often understand an algorithm better when they can compare two approaches and then build one of their own. This activity helps students:

• explain which algorithm is better and why
• practice computational thinking
• write step-by-step logic in pseudocode
• connect classroom concepts to real-life situations

The structure also makes it accessible for a wide range of learners because it moves from guided analysis to independent creation.

Great for:

• AP Computer Science Principles
• Code.org CSP
• algorithms and programming units
• middle school advanced CS classes
• intro programming and computational thinking courses

Low prep for teachers:

Everything is ready to print and use. The included answer keys and rubric make grading straightforward, and the project can be used across one or two class periods depending on how much writing or discussion you want students to do.

This is a strong addition to the Code.org Algorithms unit when you want students to complete something more thoughtful, applied, and project-like at the end of the unit.
