Logic Gates & Truth Tables Unlocked

Year 10 Technology Understanding Boolean Logic Building Computational Thinking

What Are Logic Gates?

Electronic switches that process binary inputs Make decisions using 0s and 1s (False and True) Building blocks of all digital devices Control the flow of electrical signals

The Six Essential Logic Gates

Truth Table Construction Challenge

Work in pairs to complete truth tables Start with simple AND and OR gates Check your answers with your partner Raise your hand when you need help

AND vs OR Gate Comparison

{"left":"AND Gate: Output is 1 only when ALL inputs are 1\nOR Gate: Output is 1 when ANY input is 1\nAND Gate: Like multiplication in binary","right":"OR Gate: Like addition in binary\nAND Gate: Requires unanimous agreement\nOR Gate: Requires at least one agreement"}

Quick Check: What's the Output?

If Input A = 1 and Input B = 0 What would be the output of: • An AND gate? • An OR gate? • A NAND gate?

Design Your Own Logic Circuit

Create a circuit using at least 3 different gates Draw your circuit using proper symbols Complete the truth table for your design Explain one real-world application
