Make coding fun and accessible with these engaging Mouse Robot Coding Challenge Cards for K–3! Perfect for introducing early computer science skills, this resource helps students practice sequencing, loops, and basic algorithmsusing a hands-on mouse robot (such as a Code & Go Mouse) or as an unplugged activity.

These challenge cards guide students to think like programmers as they plan, test, and improve their code. Whether you’re teaching in a computer lab, STEM class, or classroom center, these activities build strong problem-solving and critical thinking skills in a developmentally appropriate way.

What’s Included:

• Coding challenge cards with visual paths and goals
• Activities focused on sequencing (step-by-step directions)
• Introduction to loops/repeating patterns
• Opportunities for debugging and fixing mistakes
• Printable, low-prep format

Skills Covered:

• Sequencing (ordering steps correctly)
• Loops (repeating actions)
• Algorithms (planning directions)
• Debugging (finding and fixing errors)
• Early coding and computational thinking skills

How to Use:

• Students use a mouse robot to follow the path on each card
• Plan the code before running the robot
• Test and adjust (debug) as needed
• Can also be used as an unplugged coding activity without a device

Perfect For:

• Kindergarten, 1st grade, 2nd grade, and 3rd grade
• STEM centers or rotations
• Computer lab / technology class
• Early finishers or enrichment
• Sub plans (easy, low prep!)
