Pattern Rules and Predictions is a Grade 3 computer science worksheet resource focused on algorithms and problem solving through numeric, visual, and action patterns. Students examine how patterns change or repeat, identify the rule that organizes a sequence, and use that rule to predict what happens next.

What students practice

• Identify rules in number patterns such as adding or subtracting the same amount.
• Recognize repeating parts in visual patterns using shapes and colors.
• Follow action patterns and connect repeated steps to simple program behavior.
• Use evidence from several parts of a sequence to make a reliable prediction.
• Explain how pattern rules can help people organize information and anticipate the next step in a program.

The reading passage connects pattern thinking to computer science with examples including 2, 4, 6, 8, repeating shape sequences, and a robot that moves and turns in a repeated cycle. Students then apply those ideas to pattern rules, predictions, and simple program steps.

Practice that moves from recognition to explanation

The worksheet uses a varied sequence of activities so students encounter the same core ideas in different ways. A pattern-focused dialogue introduces the topic, followed by a matching activity and a cloze passage that reinforces vocabulary such as pattern, rule, and prediction. A labeled diagram provides a visual task, while the reading passage gives students a clear computer science context for pattern recognition.

Multiple-choice questions ask students to identify rules, continue sequences, recognize repeating action patterns, and explain why patterns are useful in computer science. True-or-false statements provide quick checks for concepts such as repeated actions and evidence-based predictions. Short written responses require students to explain why programmers should check several parts of a pattern, determine a rule and next value, and describe a repeating action sequence. An extended response asks students to connect pattern recognition and rule finding to predicting what happens next in a computer program.
