👩‍🏫 Teacher’s Guide

Objective
Students will use boolean logic (AND, OR, NOT) to evaluate simple true/false statements and connect it to conditions in programs.

Teaching Notes

• Use truth-table style examples but keep small and visual.
• AND means both true; OR means at least one true; NOT flips true/false.
• Connect to real life: AND = needs both, OR = either option.
• Relate to if statements: conditions often use boolean logic.

🧒 Student Worksheet

Concept and Helping Material

Boolean logic uses true and false. In programming, AND means both conditions must be true, OR means at least one is true, and NOT changes true to false (and false to true).

Computer Vocabulary and Definition

• — A value that is true or false.
• — Both conditions must be true.
• — At least one condition is true.
• — Changes a value to the opposite.
• — A rule that can be true or false.

Computer Prtactices

• Truth practice: Fill in results for 8 simple AND/OR/NOT examples.
• Real-life logic: Write 3 AND rules and 3 OR rules from daily life.
• Condition building: Create an if rule using AND (if key pressed AND score>5).
• Logic cards: Sort statements into AND, OR, or NOT groups.

Reflection

• What does AND mean in programming?
• Where might you use OR in real life?
