Debug the algorithm lava cave puzzle for 3rd to 5th grade: a cave map and three algorithms, each with one bug to find and fix. Answer key included. Part of our Hour of Code holiday activities collection.
How do I use this resource?
Have students trace each algorithm on the map with a finger or pencil before circling the bug. Partners can then write a new buggy algorithm for each other.
What students will practice
- Gives 3rd grade students seasonal counting, vocabulary, and fine-motor activities themed around Christmas and Easter.
- Builds early counting and matching skills alongside coloring and cutting practice that strengthens pencil control.
- Works as low-pressure seasonal filler for the days around a holiday break, not core skill instruction.

What is the Debug the Algorithm: Lava Cave?
⌄
Page 1 has three movement rules and a cave grid with lava squares and Gems A, B and C. Page 2 has three algorithms of 3, 5 and 7 steps to reach each gem, each with one wrong step, and lines to write the bug and the fix. Answer key included.
Can I use the Debug the Algorithm: Lava Cave at home and in the classroom?
⌄
Yes. We made it for 3rd Grade to 5th Grade holiday activities, and it works the same at home or at school. Families print it for one child and keep it where they will use it every day. Teachers print a copy per student or one for the whole room, whichever the day needs.
How many 3rd Grade to 5th Grade Hour of Code resources are there?
⌄
4 printable resources, all free to preview. Downloads are included with a ClassWeekly free trial, and every page prints on standard 8.5 x 11 paper.
What age are Hour of Code resources for?
⌄
These are written for 3rd Grade to 5th Grade students, roughly ages 8-11. Many teachers also use them a grade up for review or a grade down as an extension, so use the preview to judge the fit for a particular child.
Can I use these Hour of Code resources for homeschool?
⌄
Yes. Nothing here assumes a classroom of 25, so they work the same one-to-one at the kitchen table as they do in a 3rd Grade to 5th Grade classroom, a learning center, or a tutoring session.
