Flowcharts and process modeling help Grade 7 Computer Science students turn algorithms into visual steps they can trace, interpret, test, and improve. This worksheet focuses on how standard flowchart symbols represent actions and decisions, how arrows guide a process, and how branching paths determine what happens next. Students also investigate logical errors that can make an algorithm incomplete or difficult to follow.

From Symbols to Decisions

Students explore the building blocks of a flowchart, including ovals for beginnings and endings, rectangles for actions or processes, diamonds for decisions, and directional arrows for the sequence of instructions. A cloze passage reinforces this vocabulary, while matching and diagram-labeling activities give students opportunities to connect symbols with their purposes.

The reading passage, How Flowcharts Model Processes, demonstrates these ideas through a classroom tablet permission scenario. Students follow two possible outcomes: issuing a tablet when permission is granted or displaying a message when permission is needed. The example makes decision branches concrete and shows why both routes should lead to a clear ending.

What Students Practise

• Recognising standard flowchart symbols and explaining their functions.
• Tracing instructions, arrows, conditions, and alternative decision paths.
• Interpreting algorithms that represent everyday procedures and simple computing tasks.
• Identifying missing arrows, unreachable steps, unclear conditions, and unnecessary repeated actions.
• Evaluating how testing and revising a diagram can improve its logical completeness.

Multiple-choice questions and true-or-false statements check students' ability to interpret flowchart logic. Short-answer prompts ask them to explain decision branches and investigate inaccessible steps. An extended-response task challenges students to design a school library flowchart that checks book availability, describes the possible paths, and explains how to test and improve the process.

Included in the Resource

• Computer Science worksheet covering flowchart symbols, process sequences, decisions, and logical troubleshooting.
• Dialogue, matching, cloze passage, labeled diagram, and reading comprehension activities.
• Multiple-choice, true-or-false, short-answer, and extended-response questions.
• Separate teacher guide PDF with learning objectives, teaching tips, discussion questions, and common mistakes.

Classroom Uses

Use this Grade 7 algorithm worksheet during an introduction to computational thinking, as guided practice after teaching flowchart conventions, or for independent review of branching logic. The reading passage provides a shared example for class discussion, while the written responses encourage students to justify their reasoning rather than simply identify symbols. The library-system design task can support an individual written assignment or a follow-up discussion about how to represent a process clearly.

Designed for general Computer Science instruction, this resource gives teachers a focused way to assess how students read and evaluate visual algorithms before moving on to implementing processes in programs.
