Logical decisions and branching algorithms are the focus of this Grade 4 Computer Science resource, helping students connect everyday yes-or-no choices with how computer programs follow conditions, choose paths, and produce outcomes.

What Students Practice

Students identify conditions and decisions in algorithms, explain how a yes-or-no condition creates branching paths, predict outcomes by following logical instructions, and design a simple decision-making algorithm. The reading and questions introduce key vocabulary including algorithm, condition, branching, logic, path, action, and outcome.

Student Activities

The resource combines a dialogue, matching activity, cloze passage, labeled diagram, reading passage, multiple-choice questions, true-or-false assessment, short-answer questions, and an extended response. Examples include deciding whether a game player has a key, determining what a robot should do when its path is blocked, interpreting a battery warning condition, and identifying the decision shape used in a flowchart.

Included Teacher Support

• Student worksheet activities covering algorithms, conditions, logical decisions, branching paths, and outcomes.
• Teacher Guide PDF with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes.

Classroom Use

Use this computer science worksheet for direct instruction, independent practice, review, or assessment within an Algorithms and Problem Solving lesson. The reading passage gives students a clear model of branching through a locked-door game example, while the later tasks ask them to apply the same reasoning to robots, weather reminders, batteries, numbers, and everyday decisions.

The extended response moves beyond recognition and asks students to construct a branching algorithm for deciding whether to take a filled water bottle on a school trip. Students describe the condition, explain both possible paths, identify the final outcome, and explain how both paths could be tested.
