Python Turtle Maze Challenge – Introduction to Algorithms, Iteration, Computational Thinking

Engage your students with this interactive Python Turtle activity that builds key computational thinking skills, including decomposition; algorithm design; pattern recognition; and iteration, in a fun and accessible way.

This hands-on coding lesson begins with a simple paper-based maze activity to introduce the concept of using algorithms, moving on to using loops to improve efficiency. Students then apply their understanding by editing a pre-written Python Turtle file to control a mouse navigating a series of mazes to get the cheese.

• Ideal for KS3 or beginner Python learners
• Perfect for introducing iteration and algorithms
• Includes multiple mazes and opportunities for creative extension

What’s included in the download:

• Full teacher guidance with clear setup instructions
• Student maze PowerPoint (printable or digital)
• Presentation slides explaining the task, how iteration helps, and code walkthroughs
• Python Turtle file with graphics in a ready-to-use ZIP folder
• Solution file for the first maze in a separate ZIP folder
• Five engaging mazes + a blank template for students to design their own

Students love this activity! It’s a fantastic way to introduce key programming concepts through visual problem-solving and game-like tasks.

Perfect for Computer Science teachers looking for a ready-made, high-quality Python lesson that promotes logic, creativity, and engagement.
