Activity 01
Boolean Logic Card Sort
Provide students with sets of cards representing simple statements (e.g., 'The sun is shining', 'It is cold'). Students then use operator cards (AND, OR, NOT) to combine these statements and determine the overall truth value, sorting the results into True and False piles.
Explain how everyday decisions can be modeled using simple True/False conditions.
Facilitation TipDuring Truth Table Builder, have pairs alternate roles: one fills values, the other checks for patterns in AND, OR, and NOT outputs before moving to the next row.

Activity 02
Decision Tree Construction
Challenge students to create a simple decision tree for a real-world scenario, such as choosing an outfit or planning a weekend activity. They must use Boolean operators to define the conditions at each branch point, illustrating how logic guides choices.
Construct a scenario where the 'NOT' operator changes the outcome of a logical statement.
Facilitation TipFor Logic Scenario Cards, limit each small group to three scenarios so they focus on quality debate rather than rushing through cases.

Activity 03
Truth Table Creation
In pairs, students construct truth tables for the AND, OR, and NOT operators. They then extend this to create truth tables for simple combined expressions, such as '(A AND B) OR C', reinforcing systematic evaluation.
Analyze the fundamental role of Boolean logic in computer operations.
Facilitation TipIn Decision Relay, keep the relay short—three to four stations—so students stay engaged and errors get immediate peer correction.

Start with physical props: cups labeled True/False, colored cards for AND/OR/NOT. Move quickly to written truth tables, since research shows visual mapping reduces misconceptions about operator precedence. Avoid long lectures; instead, use frequent quick-checks to surface errors early. Emphasize that Boolean logic is about clarity, not opinion, so students learn to defend their reasoning with evidence from truth tables.
Students will correctly define True and False, operate AND, OR, and NOT, and explain outcomes using truth tables and real-world scenarios. They will recognize inclusive OR, understand NOT as statement inversion, and justify decisions with Boolean expressions. Mastery shows in clear reasoning, not just correct answers.
Watch Out for These Misconceptions
During Logic Scenario Cards, watch for students who treat OR as exclusive, saying 'only one snack can be chosen.'
Prompt groups to test both 'apple OR banana' and 'apple OR apple' with props, showing that True OR True still yields True, reinforcing inclusivity through concrete cases.
During Truth Table Builder, watch for students who apply NOT only to single letters, not full expressions like NOT (A AND B).
Ask pairs to mark where NOT applies to the whole expression in their tables, then re-evaluate outputs to see how inversion changes the outcome.
During Logic Scenario Cards, watch for students who say Boolean logic only applies to computers.
Ask groups to replace 'computer' references with daily actions, such as traffic lights (AND for green safety) or recipes (NOT for 'no salt'), then justify choices aloud.
