Debugging Logical Errors is a Grade 5 Computer Science resource focused on algorithms and problem solving. Students examine why a program or solution can follow an organized sequence yet still produce the wrong result, then use tracing, testing, and reasoning to locate and correct the mistake.

Build Practical Debugging Skills

The resource develops students' ability to identify logical errors in sequences and flowcharts, trace steps to find where results first differ from what was expected, and use testing to check whether a correction improves the solution. Students also distinguish a logical error from a solution that is working as intended. The reading passage reinforces key ideas such as incorrect conditions, wrong flowchart branches, tracing, expected results, actual results, and careful testing.

What Students Practise

• Dialogue-based reasoning about debugging and logical errors
• Matching related debugging concepts and ideas
• A cloze exercise focused on tracing, reasoning, sequences, flowcharts, branches, and conditions
• A labeled diagram activity connected to debugging steps
• Reading comprehension about logical errors, tracing, testing, sequences, and flowcharts
• Multiple-choice questions requiring students to apply debugging concepts
• True-or-false statements that check understanding of logical errors and debugging
• Short responses explaining tracing, conditions, and careful testing
• An extended response asking students to explain a complete debugging approach

Useful for Classroom Practice

Use this Grade 5 computer science worksheet during an algorithms and problem solving lesson, as independent practice, or as a review of logical errors and debugging. The questions move students from identifying concepts to explaining how tracing and reasoning can reveal the first point where a solution goes wrong. The flowchart-focused tasks also give students practice following arrows and checking decision conditions when a solution takes an incorrect branch.

Teacher Support Included

A separate Teacher Guide PDF is included with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes. This gives teachers additional support for introducing the debugging process, discussing common reasoning errors, and guiding students as they test and correct solutions.

This resource provides focused practice with logical errors, debugging, tracing, testing, sequences, and flowcharts while keeping students focused on the reasoning behind a correct solution.
