π Topic Summary
Unplugged activities for teaching Boolean logic involve engaging learners in understanding logical operations (AND, OR, NOT) without using computers. These activities often use everyday objects, scenarios, or physical movements to represent true/false conditions and logical operators. By manipulating these objects or scenarios, students can visually grasp how different logical conditions combine to produce specific outcomes, building a solid foundation for computer programming and digital electronics.
π§ Part A: Vocabulary
Match the term with its definition:
| Term |
Definition |
| 1. AND |
A. Inverts the input; if the input is TRUE, the output is FALSE, and vice versa. |
| 2. OR |
B. A logical operator that returns TRUE if at least one input is TRUE. |
| 3. NOT |
C. A value representing truth or falsehood. |
| 4. Boolean |
D. A logical operator that returns TRUE if and only if all inputs are TRUE. |
| 5. Expression |
E. A statement that evaluates to TRUE or FALSE. |
Answer Key:
- π 1-D
- π 2-B
- π 3-A
- π 4-C
- π 5-E
βοΈ Part B: Fill in the Blanks
Complete the following paragraph using the words: TRUE, FALSE, AND, OR, NOT.
Boolean logic uses the values _________ and _________. The _________ operator returns true only if both inputs are true. The _________ operator returns true if at least one input is true. The _________ operator reverses the input.
Answer Key:
- βοΈ TRUE, FALSE, AND, OR, NOT
π€ Part C: Critical Thinking
Imagine you're creating a filter for a website that shows only items that are both 'Available' AND 'On Sale'. Explain how Boolean logic is applied here, and why using the 'OR' operator instead of 'AND' would change the results.
